Next project - Railbus

 The starting point will be Sylvanian families tram, picked up for £5 in a local charity shop.  Comes with control consoles and a couple of seats (spare seats are available online).

The cab ends are suitable, but the sides not so....

It will have some running gear using a chassis with 25mm diameter wheels off an old Marklin(LGB) toy train diesel which cost me ~£60 from Ebay.
