hi -everyone -got one of these from two jags -cleaned the wheels and the axles where the bronze contacts are and it now runs very well -however I think that having the contacts without any shields next to where the wheels are lubricated is a bit iffy-but it certainly runs well and is well put together -really chunky -but does anyone know what scale these are because if they are 1-28 it would make the loco 14 ft tall which seems a bit much -also does anyone know what class of engine this was actually based on or is it a kind of make believe -regards to all
