Buffalo E7 Kagayaki PC Mouse

On the way back from Shimoda to Tokyo, I happened upon a delight in the shopping magazines found in the a seat-pocket on the Odoriko. I'd actually already scoured Osaka and Tokyo for this delight, but all shop assistants (Yodobashi, Bic Camera, etc...) had never even seen the product.

Little did I expect to find it in, what we declare in Australia, as home-shopping dodgy magazines. But, there it was... and a friend in Japan managed to order it for me then and there on the train! It then arrived only a few days after I returned to Oz.

Under those delicious 'older gentleman' dark chocolate KitKats is a Buffalo USB Mouse. It's a standard form-factor with fantastic markings. Buffalo have taken the time and painted them in line with the E7 shinkansen.

DSC09393 DSC09391 DSC09392

Further than this, they've even put a serious amount of effort into the packaging.

The artwork on the outside of the box is a lightly water-coloured scene of the Shinkansen bolting somewhere north.

I love it that they've made the box out of plastic. The mouse is centrally on display, with all appendages neatly concealed in the base of the packaging.

DSC09394 DSC09396 DSC09397

Opening it felt like unfolding origami. The intricate design perfectly fit the coiled cable and documentation.

DSC09398 DSC09400 DSC09404

Once out, I found it to be smoother than I had expected. It has a very glossy finish and is slippery to the touch. Fortunately, the sides are covered in a rubber panel, which provides a nice level of grip.

DSC09405 DSC09407 DSC09408

The best part about this mouse is that the scroll wheel is legit. The wheel is clicky and can be pressed without rotating. I've used newer mouses in the past that had very light-touch wheels that even had momentum if you spun them too quickly. This wheel has the exact friction point I've been looking for.

Power Mac 7200: PCI USB Cards

USB has been around for a long time, it seems. Longer than I'd originally thought. For fun I wanted to try and get this relic of a PowerPC into the less-than-stone ages and, well, plug things in without having to reboot. USB would provide this and I had a few devices to try out.

There's information on what OS' support USB here at lowendmac. My mileage varied... but I actually think it was because of faulty/old hardware rather than software incompatibilities.

Belkin F5U220

20151025 111909The card shows up in System Profiler but there is no power on the USB bus. I plugged a $10 HP Mouse in and the LED/Laser didn't glow. It seems this card is only good for Beige G3s or higher? Or could this card just be faulty?

OS 9.2.2 had installed and loaded the USB extensions... so it seemed that it wanted to do something with the card, but failed.

Adaptec Duo Connect PCI Card AUA-3020

20151025 111955This card comes with 2 FireWire and 3 USB 2.0 Ports. I plugged it into the PCI slot and booted up. I had already installed OS 9.2.2 with the previous USB card in, so the USB extensions were all there. Plugging in the same HP Mouse saw the light glow underneath. It worked!

Right-click just acts as normal click, so it effectively becomes a one-button mouse. I'm sure you could install something like USB Overdrive to make the buttons and scroll wheels more functional.

Opti FireLink BG-3800-00 UH-275

20151025 112011This is another PCI USB 2.0 Expansion card. Most USB tutorials for these older-style PowerMacs mentioned this chipset, usually recommending it. I found one on Ebay for under USD$10.

It worked perfectly on installation. No configuration necessary. The mouse lit up and was functional straight away.

OS9.2.2 and USB Keyboards/Mice

20151025 111849The USB cards will apply power to the bus very early in the boot process, but the devices wont actually work until the last icon on the desktop is loaded. It's still recommended to use your ADB equipment (or at least keep it for emergency purposes.)

Both the HP USB Mouse and Apple Keyboard (from a future iMac) worked perfectly fine.

LITE-ON DVD Drive

20151025 150659I plugged in my portable eSAU108 DVD/CD Writer. On the Adaptec Duo, I only got a flashing red light on the unit. It seems that the card does not output enough power for the device to function correctly. On the UH-275 USB Card, the drive worked perfectly.

Further research indicates that the drive has a smart USB power detection feature. The LED will flash red if it needs to suck power from two ports. So it seems the Adaptec correctly limits the power, whereas the UH-275 can push out more milliamps.

USB Overdrive

Downloadable from here, I assumed this would give me left-click and scroll-wheel mapping... instead it just stopped the HP Mouse from working at all. I gave up on it pretty quickly.

Does the USB get passed through to the DOS Card?

No. Even worse... if you have a 2-button mouse on the USB, the second button does absolutely nothing on the Windows side. It makes perfect sense but can be really confusing when you still have to command-click to get a context menu.

Shimoda, Izu Peninsula – August 2015

I'd never been to Japan in summer and therefore never been to the beaches. This area just west of Tokyo is stunning. The only issue at this time was a typhoon off the coast, preventing us from swimming. Fortunately we did get to get our feet wet.

JR East runs the line from Tokyo through to Izu, half way down the peninsula. From Izu, the Izukyu Corporation runs the Izukyu Railway which takes you right down to Shimoda. Fortunately, the JR (Super View) Odoriko services run on the private lines and will take you to the very end.

Odoriko Service

These are great trains, fast and efficient... clean too. If you happen to get a Super View, then the scenery is fantastic. They book out in summer though, so be quick. When booking you'll be able to choose the mountain side or ocean side. The ocean side seems popular, but the mountain side is fantstic also!

DSC08906 DSC08916DSC08918

DSC08915DSC08907 DSC08914

The beer on tap was a nice touch!

Shimoda Station

Once at the station, it's the end of the line and most passengers disappear off to seaside resorts for well-deserved getaways. I hung around for a little to soak in the view.

DSC08919 DSC08922 DSC08923

DSC08925 DSC08926 DSC08929

The corner before the approach to the station provides a nice view of an evening. As per usual, the Japanese scenery is lush and green. An easy choice to model a railway on!

DSC08937 DSC08958 DSC08965

DSC08970

DSC08975 DSC08983 DSC08998

I even happened to find an exact model of my car! This is the first functional instance I've seen in Japan. Not bad for ~30 years old.

DSC09007

Toyota MR-2

Back at the station, the yard had a few interesting things to see. There was an inspection vehicle resting on tracks perpendicular to the actual line. Do they use a crane to get it on?

DSC09026 DSC09028 DSC09029

DSC09046 DSC09049 DSC09051

Not the best lighting, but most days were spent out at the beach! Still, the yard was quite picturesque with nice sized EMUs waiting for their next gig.

DSC09054 DSC09057 DSC09062

Marine Odoriko

On the last day, the plan was to ride this home. It's the Odoriko service run by the N'EX consist. Has a special headmark and all. Turns out that I got Hyperdia wrong and we turned up to find the old-school 185 series (not complaining!) to take us back... so much charm. Fortuantely, on the day before I managed to see the Marine Odoriko shunting for its next service.

The photos are of poor quality... I'd not had my camera on me. But you can just make out the 'anchor' headmark on the front.

Shimoda Train 7341 Shimoda Train 7031 Shimoda Train 7398

And that was a wrap. Great location for a beach holiday!

Century Southern Hotel, Shinjuku – August 2015

It was to be one night in Tokyo, whilst in transit from Hakone to Izu Peninsula. What's the quickest path? Probably a change at Odawara or Atami? Suuureee... but there's also an express train to Shinjuku from Hakone and an Express to Shimoda from Shinjuku. So, why not do it in luxury?

Hotels in Shinjuku aren't cheap... so you might as well make it count. Turns out that Odakyu has a hand in this hotel and this hotel has some stunning rooms! Check out the view from the Panorama room I stayed in!

Hakone Tozan Railway – August 2015

I've always wanted to visit this place. I have models of one or two of the trains, but didn't really know of the actual railway. It turns out that the Hakone Tozan Railway is one of the steepest non-rack railways in the world. It's really worth going to check it out.

Getting there

The Odakyu Railway will get you all the way from Shinjuku Station to Hakone-Yumoto station. If you're on JR, then take the shinkansen to Odawara station and transfer. I was coming from Osaka and caught a Hikari to Shizuoka and then a Kodama to Odawara.

DSC08634 DSC08642 DSC08645

The best bit about this is that you get to wait and watch all the Nozomis and Hikaris bolt past.

DSC08657

DSC08646 DSC08650 DSC08662

Once at Odawara, you'll need to take the Odakyu railway to Hakone-Yumoto. The Hakone Tozan Railway used to operate all the way to Odawara station on its standard gauge line. The dual-gauge portion has since been truncated back to Iruida Station.

Hakone-Yumoto Town

This little river town is picturesque and serene. The river is quite wide in the center of town and makes a lot of noise due to some shallow waterfalls.

DSC08760 DSC08776 DSC08761

DSC08774 DSC08780 DSC08781

DSC08789 DSC08798 DSC08799

I stayed at Hakone Suimeisou and loved it! Great staff and great location! It had a good view of the sweeping curve into the station. Also a very short walk.

Climbing the grade

The Hakone Tozan Railway, as soon as you depart west from Hakone-Yumoto Station, starts climbing steeply. As you can see in the photo previously, there's a sharp right-hand turn as you pass over a local road.

DSC08811 DSC08811 DSC08816

It doesn't get any less steep. Further up the mountain are three switchbacks and numerous stations. The scenery is superb. The first station is Tounosawa, which happens to be the railway that this blog is based on. I've been following it for years and it was great to finally see the area that provided the inspiration.

Switchbacks

To prevent incidents, switchbacks are used to traverse the grade. Each switchback consist of an inclining path, a declining path, a double crossover (or two sets of points) and two roads for each passing consist to pause.

Chokokunomori Station (Hakone Open Air Museum)

The main goal was to get up to the Hakone Open Air Museum and check out the sights (they even have a Picasso Gallery.) This was an easy task, as it's a short walk from Chokokunomori Station. The first afternoon, after arriving, I tried to rush there, but would've only had 20mins to check the place out, so instead I checked out the railway.

DSC08701

DSC08668 DSC08670 DSC08671 DSC08672 DSC08681

It's a beautiful area with beautiful curves and great angles for photography. The lush forests around make for perfect backdrops and I love it when you have to try really hard to take a shit photograph.

DSC08699 DSC08709 DSC08711

DSC08723 DSC08727 DSC08729

The mix of old and new rolling stock is also amazing. Anyway, the next day I made it into the museum... the view of the railway from inside was actually quite cool!

DSC08858

DSC08843 DSC08865 DSC08873

Back to the old rolling stock... the windows open... take advantage of this!

DSC08824 DSC08831 DSC08746

DSC08817 DSC08820 DSC08826

Back to Tokyo

From Hakone-Yumoto is easy... the best part is that, when choosing which Romance-car to take, the departure board actually has a picture of which series EMU is to be used. They really do cater for the train nerds. There's also a cool cafe in the station with a great view.

DSC08879 DSC08881 DSC08882

Another place to go back to...

Osaka – Imamiyaebisu – Nankai Rapi:t

Staying in Tennoji this time around meant that I was close to the main trunk like of the Nankai railway. The closest station was Shinimamiya which is a shared JR/Nankai station. It allows passengers to transfer from the loop line to the Nankai service. From here you can proceed north into the heart of Namba or south towards the Airport, Koyasan or Wakayama.

DSC08598Between Shinimamiya and Namba is one station: Imamiyaebisu. This station exists on the two east-most lines and is only really served by local trains. Its location provides a great view in both directions, from both ends of the platform.

The two tracks to the west are for anything other than local trains. The expresses will pass along these lines at moderate speeds. Most express services still stop at Shinimamiya, so they wont be full tilt.

The only real drawback of the area is the ability for services to block your view and the overpass just to the north providing unwanted shade. First world problems, really. There were even other photographers there when I visited.

Southbound View

DSC08583 DSC08585 DSC08589

Nice sweeping curves and no issues getting full consists in the frame. Nankai has some basic liveries and a lot of stainless stock. Fortunately they like mixing it up quite a bit.

Northbound View

DSC08591 DSC08604 DSC08612

Northbound is just as nice... quite a straight stretch until the final right-hand curve into Namba. And then ... the consist I was waiting for approached.

DSC08623 DSC08625 DSC08626

DSC08628 DSC08629 DSC08630

The Nankai Rapi:t is the express train to Kansai International Airport. If you're staying in Namba, or don't have a railpass, then take this train when you arrive... it's fantastic.

10Sep/150

Osaka – Super Rail Cargo

I've tried before, but always failed. The Super Rail Cargo is an express EMU freight service that runs in the middle of the night and is a hard one to photograph. Turns out though, that Japan doesn't do daylight-savings. Therefore, in summer, in the wee hours of the morning, one has a good chance of seeing this thing on the move.

One service leaves Tokyo whilst the other leaves Osaka, around the same time, nearly every night of the week. I've never tried to hunt down the Tokyo end, as it's sorta out-of-the-way down past Shinagawa. Fortunately, the Osaka side passes through Umeda, on it's way towards (and along) the Tokaido Main Line.

The Stake Out - Fukushima Station

This train runs from Ajikawaguchi yards, along the Yumesaki Line, joins the Loop Line at Nishikujo, passes Noda and then heads north where it branches off the loop at Fukushima. It's even at road-level and there's a level-crossing, so you get an advance notice of anything approaching.

I used my freight timetables as posted here to know when it might arrive. It was my last morning in Osaka, a Tuesday, and I wasn't going to miss it this time.

I was staying in Tennoji and awoke at 4am. There were no train services at that time, so I found a taxi and asked to go to Fukushima Station. The driver alerted that there was nothing to be gained in going there, but I actually stated that I hoped to take a photo and he chuckled and agreed that it was OK.

DSC08472 DSC08482 DSC08483

DSC08484 DSC08490 DSC08493

It was around 4:40am and indeed still dark.. but I was very happy to have the sun rising.. although on the wrong side for a good shot. There were lively characters coming out of Karaoke venues or bars, but also people making their way to work.

DSC08498 DSC08499 DSC08502

At 5:05am, the booms triggered and an EF66 with a short rake appeared. It seems this would be ▲59 making it's way from Suita. I think I still had my polariser on at this point, not really knowing the best way to shoot in low light. Hence the photos are quite dark.

DSC08504 DSC08506 DSC08507

A loop line service came through at 5:12am... meaning that I could've slept in a little later and taken it from Tennoji. There was no way I was going to risk that timing though.

Either way... The gates then activated again and the M250 came through!

DSC08510 DSC08513 DSC08514

DSC08515 DSC08516 DSC08517

DSC08518 DSC08520 DSC08522

Not the best photos... but for the first time I saw the actual service in flight; whilst I had a camera ready. Success!

4Sep/150

Osaka – Umeda and Hirano – August 2015

The goal was simple... there's a freight train that runs from Umeda to Hirano and there's enough time to catch it at Shin-Osaka, bolt to Hirano and catch it again. Of course... this would be correct... if Umeda Freight Yard still existed. Little did I know that, whilst waiting at Shin Osaka station, the yard had been demolished some 3 years earlier!

The timetables I posted here were initially wrong. Wherever I had 'Umeda' should have actually been 'Osaka'. I thought 'Osaka' (from the freight train timetable) meant 'Umeda'... but it actually meant the yard right next to the Shinkansen depot out past Senrioka!

Shin-Osaka Station

I waited here for a while to see the freight head through to Umeda. Instead I got to see the standard array of express trains. Mixed in with these was a freight heading to Ajikawaguchi which caught me off-guard. You can find the timetables for Suita to Ajikawaguchi here.

DSC08163 DSC08170 DSC08172

The Ocean Arrow/Kuroshio in pictured above actually left 5 minutes late. That last picture shows the driver hanging out the front of the train with the stationmaster discussing something that was preventing him from leaving. What I didn't capture was the guard bolting down the platform with a few sheets of paper that must have been the timetable/run-sheet that you see paper-clipped in the cabin. It seems the driver was issued with the wrong one, as he swapped the one in the train with the one the guard delivered. The train then departed.

DSC08173 DSC08174 DSC08176

DSC08181 DSC08184 DSC08186

DSC08188 DSC08190 DSC08195

DSC08202 DSC08203 DSC08206

It was 30 minutes past the time that the train was meant to arrive and I decided to cut my losses. These trains are usually very close to clockwork and the Ajikawaguchi train had passed... so it was time to go.

Transit to Hirano

I took the Haruka Airport Express to Tennoji (thanks Rail Pass!) and then a local to Hirano. It was a quick trip. Of course, the goal was to pass the freight yard to see if there was any activity. Instead I was presented with the following...

DSC08211 DSC08213 DSC08214

I think I let out a big 'Ohhhhh....' at that point and had fellow passengers look oddly at me. Everything clicked. I was glad I'd left, but unhappy that I'd waited so long at Shin-Osaka. This is Japan... if the train doesn't arrive 5 minutes after schedule then move on.

Hirano Station

This is a little station on the line to Nara. I've posted the freight timetable for this yard here. It is located two stations east of Tennoji and you must take a local service on the Yamatoji Line to get there. The stop between Hirano and Tennoji is Tobushijomae and is located on the south-west corner of the freight yard I sought out. Stay on the left side of the train between these two stations and you'll get a good view of what's about to depart.

The yard has three staging roads immediately next to the passenger lines, but at ground level... the passenger lines are elevated. In these roads you'll find made up trains that have just been delivered, or are about to depart. Trains that arrive are staged here whilst either the engine that brought them runs around or the yard worker takes them away. There is a shunt road that runs right up beside Hirano station for this purpose.

DSC08313 DSC08220 DSC08225

I ventured out to Hirano on a Wednesday. As I passed the yard, I saw an EF66 about to carry out this very task. I got to the station in time to see it shunt right up next to the platform. It proceeded back into the yard and everything was quiet. There are occupation indicators line-side on the freight shunting roads that show you if anything is approaching. They'll flash if the track is occupied and stay lit if nothing is happening. Note that the flashing indicates that the road is in use. The train on the road may not come all the way up to the station. The points are situated a fair way back west and the shunting will only reach the station when long consists are being worked.

DSC08226 DSC08234 DSC08236

I followed the timetable and realised that there was an inbound freight due. From the city-bound platform, you can see the triangle to the east where the freight trains come from. It didn't take long before a freight came in, 5 minutes early. This was dragged through by an EF210. After this, there was nothing scheduled for a few hours... of course, I stupidly only looked at inbound traffic.

DSC08242I was out of time and had to head back... completely failing to look at the outbound traffic timetable. As I left at 1pm on a local back to Tennoji, I passed an EF81 on its way to Suita. Totally pissed off, I was. EF81s are a favourite and I've taken a shot of one very similar to this one before... years before! In Umeda Yard! This poor old thing has been hanging around Osaka just waiting for me to return!

I returned to the apartment only to find that everyone else was still shopping... so... knowing that Hirano was 10 minutes from Tennoji, I ventured back to see the ~2pm services (one inbound and one outbound.)

DSC08269 DSC08271 DSC08280

An EF210 came in, 10 minutes early... and then the EF66 I'd seen earlier proceeded to Suita with a short rake of flats.

DSC08286 DSC08288 DSC08291

DSC08293 DSC08295 DSC08296

There was now nothing due until after 5pm, so I decided to call it a day and visit Den Den Town. I'd come back later to catch the EF81 in action.

Hirano Station, 2nd Attempt

My second attempt was carried out on a Friday. I based my plan around the 1pm depature of the EF81. Arriving at 12, I hoped to see at least one service... but absolutely nothing came through. The yard had zero workers and zero locomotives... just a few rakes of half-built consists. As I passed the yard on the way in I could see that nothing was happening, but I waited in vain anyway. Fail.

What was worse? The platform indicators were showing 'Pass' on the nearest platform to the yards. I'd not seen a pax go through here at all... so I sat, staring at the indicator... waiting for that "Train approaching" sign. Hours. Nothing. Oh well... they must program the slots in and not cancel them.

Hirano Station, 3rd Time Lucky

This time I attacked the station on a Monday. As I passed the yard on the local train, the EF81 was not there. It had been there waiting to depart the first time I'd visited and so I was worried. This time there were other locos in the yard, but none ready to head out.

DSC08411 DSC08412

I got to the station, parched. There was nothing due for about halfa so, despite the platform board showing a 'Pass', I ventured to the city-bound platform for a beverage. There are no vending machines on the outbound platform. Lo'and'behold, my favourite EF81 bolts past just as I'm on the other side, inserting coins. I leave half the coins inserted, grab the camera and got a few photos... school kids nearby were wondering why a photo was more important than a drink...I smiled.

DSC08413 DSC08420 DSC08422

DSC08424 DSC08427 DSC08431

Not to be fooled again.. I proceeded back to the outbound platform and caught the next freight coming in. Turns out there was also a young railfan there doing the exact same thing.

DSC08439 DSC08440 DSC08447

Passing time was easy... there was a local every so often and expresses interspersed.

DSC08457

DSC08448 DSC08449 DSC08451

DSC08463 DSC08466 DSC08471

And then it happened... the EF81 came through and the world was at peace.

Akihabara Washington Hotel

This is the first post of my most recent trip to Japan. It was the first time I'd been there in Summer and I was not expecting the weather to be so damn nice. Yes, humid, slightly, but not quite tropical-humid... somewhere half-way towards out-back humid.

Anyway, the trip started in Tokyo. I usually stay on the west-side of the Yamanote Line, but this time I stayed east. Akihabara to be exact. The good thing about the east side? The Shinkansen lines run on this side, terminating at Tokyo Station.

Akihabara is north of Tokyo, so only the 'northward' Shinkansen run through. Well, the north-west-ward also run through too now. Fortunately, the shinkansen tracks are all above ground until just after Akihabara station, so there are several vantage points if you search for them.

One vantage point is the Akihabara Washington Hotel. It is actually so well known for it that they have an actual room dedicated to trains; including a model railway! (Note the single bed.)

Checking in

When booking the hotel, I left a comment requesting a room that could see the Shinkansen. I received an email response saying that this was not a problem. Upon check-in, I neglected to remind them and was first given a room staring into another office building to the south.

I returned to the counter and politely asked if my comment still existed and if there was any chance of a room looking over the tracks. The receptionists kindly oblidged... although I did hear a snicker between the two girls that the "gaikokujin ha densha wo mitai, heya kara." I couldn't tell if it was my bad Japanese or if I was a train nerd.

Room with a view

Second time lucky! The room had a great view of the Kanda River and a shrine on the opposite bank. To the right were the Shinkansen tracks heading to Tokyo. There is also an elevated flyover of the Ueno-Tokyo Line.

DSC07853 DSC07860 DSC07868

DSC07862 DSC07872 DSC07896

From here ... it's going to just be pictures. There's a vending machine on every floor... so a few beers and a bit of train watching was had.

DSC07897 DSC07904 DSC07906 DSC07914 DSC07922

Stay here, it's awesome. Just remember to check that your room has a view!

Simple Short Circuit Protection

My vintage power supply from Japan did not have short-circuit protection. I couldn't deal with this, as the brass models were also ancient and shorting out all over the shop. A little googling presented me with Homemade Circuit Projects: Short Circuit Protection. This article has a nice 'mechanical' short-circuit protector. A relay is energised to begin the power output and, on short, is tripped, cutting the supply.

There are no integrated circuits whatsoever inside this power supply, so I thought I'd go the mechanical way.

The circuit

A relay is used to allow power from the source to the output. This relay is initially de-energised. The momentary push-button, when activated, will provide power across the coil in the relay, energising it. There is a secondary feed to the relay's coil which goes via its switched output. As the relay switches, this secondary power is activated and the current then also flows across the coil. This provides a sort of infinite loop where the power through the relay contacts infact keeps the relay energised.

A short on the output causes a drop in voltage. This voltage is required to keep the relay energised, so a drop will actually de-energise the relay and cut the output power. The push-button will need to be activated once more to re-energise the relay.

Circuit placement inside the power supply

This circuit needs to be placed after the bridge rectifier as it requires DC power. It also needs to be placed prior to the direction switch, as the polarity needs to be constant and one-way around. This leaves us with the choice of putting it before or after the throttle potentiometer.

I had originally placed it between the rectifier and the potentiometer. I wanted the continuous voltage, otherwise I'd only be able to energise once the throttle was more than zero. Unfortunately, in this position I found that it only tripped when the throttle was at maximum. It seemed that the potentiometer was capable of absorbing the short if any resistance was provided. Prolonged exposure to a short would no-doubt heat the coil of the potentiometer and cook it.

Moving it to the other side of the throttle worked perfectly. Even at throttle setting '1' it would trip. Of course, it would only energise when on throttle '1' or higher. I considered adding more components to allow a secondary source to trigger the relay, but found that I could adjust my usage of the power pack. Now when wanting to drive trains, one must shift to low throttle, hit the trip switch and then throttle further.

Required Components

Based on the diagram above, you'll need 2 100uf electrolytic capacitors at 16v or higher, a diode capable of the amperage/voltage, and a relay. The relay should be DPDT if you also want the status light.

As above, you can twist the diodes together in parallel to make them suffer higher currents. I used 1A diodes and wanted to make sure they could cope with the 2A transformer... but then I got bored and twisted 4 of them together. You can then see my prototype hookup to see if it all worked.

Status Light

I wanted to know when the switch was in trip mode. I didn't want to have to pull my multimeter out each time to work out where a fault was when no power was available. To do this, I used the second side of the relay to provide a 12v source to the led inside the momentary switch. This would light in the normally-closed position. As mentioned above, the relay only provided output power when energised (Normally-Open), so I wanted the light on the NC side so as to illuminate when the power was cut off.

The switch indicated that it was rated at 12-volt and 240v. I took this to mean the internal lamp/LED? was 12v and the contacts could switch 240v. I didn't want to risk it though, so I put a 470ohm relay in series to limit the current. The resulting brightness worked perfectly well.

Case Modifications

Adding the switch wasn't going to be easy. The nicest one I could find had a huge barrel. I used the smallest drill-bit I could find and then proceeded up. I hate cutting in to metal... always worried something will go flying and take a limb off. The metal shavings aren't much fun either.

Fortunately my friend has a dremel... so we hacked away with that and made the switch fit. The best location was on the front panel. I do like the finish.

End result

It works perfectly. Setting the throttle to '1' or higher lights the switch... it always starts in trip mode and needs to be activated. Pressing the button switches modes and the relay clicks. The LED switches off and, depending on the position of the direction switch (and the power requirements of the locomotive on the track) the locomotive will start to move.

In fact, it shorted as soon as I tried to apply power to my ED100 on the test track. Turns out an axle had dislodged from its mount hole in the bogie frame and was happily shorting. After a realignment, all worked well. The bogies on these Tenshodo/KTM models have quite a bit of flex. The lateral screw isn't 100% tight and so the bogie frames can skew.
