I have cars with coil couplers triggered by sliding shoes, and when they go though my 3 in a row Postwar 022 switches from one main line to the other, they do not uncouple.
This video shows 7 Postwar oil tankers with coil couplers and sliding shoes gliding at moderate speed through three 022 switches in a row, and there is no uncoupling or derailments:
I think it was Don who said he keeps his 022 switches a little loose (not totally cemented in place). I do the same, and I also keep them level and aligned properly in order to minimize derailments.
I am very pleased with the long term performance, durability, reliability, fixability, appearance and affordability of Lionel Postwar 022 switches with fixed voltage plugs. Arnold
