REeboxx sells a 10-pack of wheels,each with a different axle length so we can really find the appropriate length for the truck we are working with.
Each axle is a different color, with a printed reference code. Makes finding the proper fit a snap!
KD and Proto are one universal length, and work for most cars.
I rebuild/upgrade the old stuff, and even found proper wheel sets for the old Bachmann 28' TOC cars made in the 60-70's.

Just bought the Spectrum 2-6-0/sound....besides lightly oiling the rods and external moving parts of the drive, are there any special things to be done before running it, or any other steam engine?
