Tested with direct connection to motor pickups and 2 of the wheels on one side are running very well, but the other 2 are not…rather mostly free-turning. It might be like this on purpose? I dont know. Note this isnt meant to pull other cars, so the current traction level is more than enough for this to run. Missing wires from powered to non-powered bogie, and lights etc. Loco will run as-is, since the wheels pick up from the track. Note currently the powered bogie is LOOSE as its mount is broken. Will need to be repaired!!!! Sold as seen, thanks! A nice little project. May be missing detail bits!
