Lima HO NS Koploper
I purchased one of these from Schaal Treinen Huis in Amsterdam after travelling on one to Groningen. The Koploper reminds me a lot of the JR West Thunderbird (683 Series).
The review? It runs like a dog due to it only having a single motorised end carriage (fortunately with all-wheel pickup) and the lighting shines brightly though the shell.
As you can see, the train I bought included an add-on carriage and all packaging. The price tag was on-par with what I'm seeing on eBay nowadays. The train was in a glass cabinet on display when I bought it and I didn't realise that the base package only contained one coach. I have since found and purchased another coach from eBay and will attempt to extend this set. You can also see in the comparison shot of the two passenger cars that they are slightly differing in colour. Unfortunately, this is just a side-effect from purchasing second-hand; I have no idea what their story is and if the main set was left in the sun too long...
Either way, it's a great looking train set.
