I'm still trying to set up my first layout but had a question about the location of block isolation points. As an example it really would be easiest to locate these with a fiber pin at the center of diverging tracks out of a switch. However, I had previous advice to move them back an inch or so from the O-31 Lionel tubular switches I use. I'm guessing this is to not interfere with that switch's anti-derail function or speed of the train/shortness of the switch or both. Is this generally true? Does the same hold true with larger switches like Ross O54 and O72 that I use elsewhere?
