I was able to get the switches and track set up today. The switches are really smooth! My MTH Premier Allegheny went through it like butter! I was able to get my American Flyer 1681 Hudson to run through them. This engine had a lot of sparking and the e-unit would cycle. I was able to lock out the e-unit (with some effort) and it would run through the switch. I also tried my old Marx Nickel Plate Road engine, and it ran through fine without cycling the e-unit. These are the 900mm switches, which are roughly O72. I think I need to get rid of all of my other switches, Ross, Gargraves, Atlas and Fastrack!
Here are pictures of the switch installed.
Here are the trains running through it.
