I repair the split gears by carefully filling the shoulders until I get an interference fit, for K&S brass tube ( tight ) this pulles the gear shut, but has to be tight enough so it still fits tightly on the axel shaft, or ! you could buy new ones. The axels in the towers are plastic and can snap off, they can be replaced with 3mm steal shaft ( or a nail ) by drilling a hole in the housing for a gentle push fit. The wheels are wrong for two rail track, the flanges are too thick, if the wheel is in good condition, you can machine the back till the flang is 1mm thick and then all is good for two rail points. Or ! buy replacement wheels. (NWSL gears and wheels ) The truck side frames tend to snap off. So this is how I fix that, and modify the electrical pickups.The angle is made from brass or aluminium edging tillers use, or some Plastruct plastic angle. For $30-50 dollars you can get a lot of fun from these models, and it amazing how bullet prof they can be, and with detailing they can look great to.
