See you can run more than trains on your rails!
If one hurries on can still get a VW Micro bus for 45mm track, made by Brekina http://www.trainli.com/draisine-yellow-p-965.html
Sales have been disappointing for Brekina, the items may not be re-run.
BTW a really original operation is on the CFV http://en.wikipedia.org/wiki/Chemin_de_fer_du_Vivarais

That has to be a blast!
Just goes to show you that there is a prototype for everything.
I have that Brekina, I have to say that I really like it and can recommend its quality. Its really Eurocentric though…its a little odd looking on an American layout.
