I just bought a Rivarossi 0-4-0 and the loco's wheel flanges are too deep for code 83 track. As these date back to the 1960s has a fix for this been found? I'm thinking of running power through two files and let the wheels spin and grind off some of that depth. Also the tender is brass and has a 'Japan' sticker on it. Is this original? I’ll post up some pics on the recent purchase thread.
