This part:
Attaches to the locomotive frame via a screw in the hole at the top. The other end slides into the square hole in top of the crosshead as seen here:
Problem is, it keeps sliding out. When this happens, It jams against the top of the crosshead and jams the locomotive up.
The frame is in good condition and straight.
The cylinders (which the crosshead guides mount to) also seem fine.
Still, it keeps popping out and binding the locomotive up. Any suggestions? I've tried bending the area on the crosshead that holds it upward (only slightly) but it only seems to work for a short while.
Also, the trailing truck seems to "bounce" down the track. It stays on for the most part but does derail from time to time. It doesn't seem to hold the rails very well. The wheels spin freely, seem in gauge, and the truck swings freely. Any idea why this might happen?
