We just about started over with this Eng. Took it down to and started rebuilding the drive. Re wire it due to all three run if have found are difference or the running gear is difference. It took three Eng. to get this back together to run like we wanted it to… Over size 24v motor. Had to make a lot of detailed parts and fig out a coupling that will work.
We run track power so had to wire up the tender beside all axles on Eng. built in a back up light by recessing in the tender with markers LED’s built in. Move head and marker light to our specks. Still want to animate the Eng head turning and waving yet. Found a 1- 1/2 v. geared motor to run it using constance lighting from the cab and fire box.
Michael Glivan is building up another drive with bearing and difference block/ motor mounting idea. Most of our brass.
Anyway it a Jewel for us… Looks like we can add about 2 or 3 more pounds in it. It will pull a house and out run any Eng on the tracks if let it. oh need to change out the Sound card batt to a 1.3 ah. or better yet to.
Here is the link of just running it around the short part of the layout a few days ago…

You have a water wheel or something in the background?
