Operating cars and coil coupler cars with sliding shoes

I am having a lot of trouble with cars derailing while backing up through 1122 switches. I finally figured out that it was only my operating cars and coil coupler cars with sliding shoes. I don’t know what it is called, but the wide center rail part of the switch is part of the problem. The sliding shoes are catching on it and it is just enough to lift the car enough to allow it to jump the track. Is there any solution to this problem? Can the part of the switch be modified in some way so the shoes will ride over it rather than catch? Or should I just retire all my sliding shoe cars and just use the ones that will work?

Thanks

There is a way to file the profile of the shoes to look more like a ramp at each end(accentuate the bevel more than stock). It may take some experimentation to get the right shape for your “hang-ups”.

The Ross Custom Switches website has a FAQ about fine-tining the switches, but the shoes are so cheap and easy to replace that you’re better off experimenting with the cars instead of bungling up the track.

The filing method Rob suggests is pretty common procedure. Also check that the metal contact head within the shoe slot does not protrude beyond the slot whether it be a worn shoe or the contact has pressed itself beyond. The shoe should spring freely as well. If not, shoot a dab of CRC plastic compatible tuner cleaner/lubricant into the mechanism to try and free it up. The spring may need to be replaced if it is too stiff.
