Doodlebugs seem to be popular in HO, I'll bet that VW (could you call it a rail bus) would be a big seller just because it's so odd. Thanks for posting...

But hey, you could have all kinds of fun with that.
If it was pulling a military supply train the cab would be a Hummer complete with upper gun mount.
If it was a 70s style bullet train, it would be the nose of a 75 Charger or a 72 Chevelle SS.
A modern day bullet train would have a Lamborghini or Ferrari front.
Those would all be cool!!
