Lionel 2642 Pullman truck and Ross switches don’t get along.

Its the sliding shoe hitting the guard rail (which then derails the truck and trips the breaker).

Try this: put a track pin in the end of the guard rail, and bend the end sticking out down until it touches the tie. Essentially, you're making a ramp to push the shoe up and over the guard rails on the switch.

If you dont need it, removal of the shoe would also probably do the trick.

I've found putting a dab of Goo on the upper side of the shoe and on the area on the truck where the the shoe will make contact with it; then heat the area with a blow drier until the Goo bubbles; finally push the shoe into the truck holding it there for 15 - 20 seconds. The shoe should now clear the guard rail -- problem solved! If you should ever want to return the shoe to its original position just remove the Goo with the tip of a hobby knife or something similar.

Thank you guys!

That solved the first problem. The last truck seems to have a lot of slop in the wheelsets, they are are making contact on switches. Ill have to see if any of spare wheelsets are better.

Which Ross switch are you having an issue with?  072, 054, curved?

It is an 072 wye, but everything else works and has worked for years. Even the other tinplate Pullman wheelsets are ok , Just that last wheelset. I am guessing the fiber disk is wore down allowing the width of wheels to be too narrow.
