The outside of this model for 0e is an exact scale copy of GTM Silvolde, one of the few remaining Dutch tram way locomotives from the famous manufacturer Backer & Rueb. The original can be seen in the narrow gauge museum in Valkenburg (Zuid-Holland) in the Netherlands. The inside is based on another tram locomotive I've designed before. It is complete and accurate detailed and it's the part most people don't model this extensively, as it is a very complicated contraption to make yourself. This is a fast and easy way of having your own Backer & Rueb tram driving in 1:45.
I haven't developed a drive for it (yet), so you'll have to be creative yourself. There is enough space inside to add one! The prototype axle distance is 1200mm, which is 26.66 mm in 1:45. The diameter of the wheel is originally 800 mm, which is 17.77 mm in this scale.
