That is not what I understood @gunrunnerjohn to say at all. I herd him say he has a 3 switch configuration with Ross switches and doesn't have a problem, and that there is no reason O22 switches cannot be in the same configuration as long as they are serviced to ensure that the decades old internal internals are intact and capable of carrying power all the way through just as I had discussed earlier. Following @Mannyrock, you will see the type of equipment he is running is actually prone to one of Ross' downfalls is that they do not deal with sliding shoes of engines and operating cars passing through Ross Switches. The design of the Ross Switch will cause the engine / car to uncouple when the slider shoe crosses the center rail of the switch. Operating cars with slider shoes will activate when going through a Ross Switch. Sure, you can modify the the Ross switches and such. Another thing to note is that @Mannyrock is using O gauge profile tubular track - Ross switches are O27 profile. Not insurmountable, but again, not as plug and play as the bulletproof standard O22 style.
Again, this is a potential issue for any type of switch with any track system and not unique to the O22 nor does Ross eliminate it. Looking at the generations of equipment @Mannyrock is operating, they were all manufactured at the time when O22 was the gold standard and tested/designed to navigate them.
True, Ross, Curtis, Atlas, I've power routed many of them with some success.
