Love the JNR Kihas! I have over 40 of various types. The Kiha 40s are a classic, the tomix models really captured the look of the prototype. Good luck installing the air horn covers on the front though, its a trick to get them in!
One does, the other is a trailer. I have another, double cab version that's white (I think) with a stripe. I don't know what it is about them, but I love them!
