Southern Pacific Switching Layout

[FCIN]

The only thing I did to my Peco turnouts was lay them down, and let the trains ride through them. Not a SINGLE instance of them causing ANY sort of problem.
But then, I only have 40+ turnouts....If I were to have twice that, maybe one would give me trouble....

NMRA compliant..?? I would ask the NMRA to change their specs to fit the characteristics of Peco turnouts....

Agreed! Never have had to make any modification to a Peco turnout and have been using them for many years now. Never had a derailment in one of their turnouts, unless a car had wheels that were out of gauge, and that was very rare. After having used both the electro-frog and insul-frogs, I just prefer the insul-frogs because of the simpler wiring. Plop down the turnouts and track, connect one set of power feeders to it and I'm off and running! Sure has made testing out potential track arrangements very enjoyable.
