Update on the J1-a. While the engine now runs through the S curve mechanically, electrically it's another story. Apparently my wire splice to fix the wire that broke on the real roller created a dead short. The engine no longer runs and trips the Z-4000 breaker. It's now in the repair cradle waiting to be completely disassembled (remove boiler, so I can do a proper splice on that wire and get rid of the jumper from the front roller to the rear.
I post an update about the fix when I do it.
I did get four more tracks powered so 33 down and 5 more to go. The engine servicing tracks are now live.
