In the world of model Railways Railroad signals are usually the last thing a modeller will add to the layout.
When I designed Harburn OO I built in what signals I wanted and how I wanted them to function. That being not prototypical but to give a visual aspect to train movement.
There are many ways to wire and control your signals DCC or DC and how to use Rocrail to control them.
I am no expert in Rocrail and am sure there are many out there who are so feel free to like comment subscribe.
