One more passenger train PM'ed.
B&O EM-1 2-8-8-4 and passenger cars. One engine fix and one car fix.
The EM-1's motor was moving but the drivers weren't so it's usually the tubing. Not sure why I left the original black tubing from motor to gears while installing a decoder!
Easy fix. New tubing.
One car derailed. On one curve the plastic diaphragms were touching each other, binding, and derailed the car. Re-drilled/tapped a new hole closer to the end of the car for the coupler.
Not scale but functional.
14 more car wheels cleaned and running well. Looks like I can get about 2 passenger train sets done in a day. Noticed some freight car wheels are, also, dirty. Probably will try a paper towel on the track with a solvent and run the cars over it.
