Question on several trains on one layout

It is an alternative operating system, signals are part of an alternative operating system. So which system are you using, or is all just another Mark Newton fairy story about his layout operating..

CTC and systems using signals can include ATP expert. ATP is only one control method DC is good at. DC is also good for most systems using signals, and systems using blocks so your ATP claim is largely another irrelevant argument from an expert who does not have much layout wiring experience or knowledge, DC or DCC.

I thought this thread died weeks ago???

It did, but it takes the f****it long to think of a reply...

A reply which shows you don't know anything about layout wiring or operating methods that work. Your use of foul language confirms your weak argument.
