I just aquired a few Athearn Rubber Band drive locos. On some of the units there is nothing holding the trucks.One would thinl there would be a spring clip holding them in place , but there does not seem to be any provision for a clip.The others which I believe to be later has the trucks held with a screw.Was this a factory change or a modification by a previous owner.
Are replacement bands available or are any other bands available that will work.
