This van used to be an all-rail machine just like this old truck sitting across from it:

For some reason he had his rails wheels taken away, and has been sitting like this for quite some time. I know that today when hi-rails dominate, such a van seems like a rediclous idea, however the GWWD line reaches remote areas that are only acessible by rail in the winter. Futhermore running this van sure beats using their 1921 Railbus or have a coach hooked up to a RS-23. Speaking of which, GWWD 200 can be seen in the background. If you look carefully, you'll also see a green 50' box in the back, there were at least three, with their trucks removed - converted to sheds. I believe they have since been scrapped.
