The last 4 Gargraves switches I received had the center section redesigned from a solid coffin shaped piece to separate rails. This has caused multiple shorting issues when running 6 wheel trucks or cars with wider wheels, and uncoupling / shoe problems with cars with shoes. Below is a correspondence with Mike from Gargraves, and pictures of what had to be done to modify them to work reliably.
