Dennis,
Using Dispatcher and auto engineers I can run 7 trains on a Pi3, at any one time 3 can be in motion, and the others waiting, so 7 evalutions take place on a sensor change. That is with full signalling that uses the extended dcc packets. The major bottle neck is on the loconet, (I use digitrax) and on the dcc for the signals thru the command station. Excessive ramping demands and stopping by speed profile can be further drains on cpu power. Both can be eleviated by running in 28 step mode.
The number of concurrent trains is not the limiting factor, it's how many events are happening at once and how much time it has to react in. So a 60x60cm nscale trolley layout with 3 cars might bring the pi to it's knees, but a 4 hectare garden railway with 10 trains can be handled with ease.

Dennis,
I agree with the maybe, depends a lot on HOW you're planning to automate. I use JMRI Dispatcher for my layout, and I've had 5 trains scheduled, with 3 active at once, with no issues running on my RPi3.?
