I am trying to add signals to my route, the vast majority will come from the Peak Forest route as the route is based in the late 1950's. There are some additional signals I would like to use that are not part of that route i.e. UQ_ground signals. These are only available on another route and I cannot seem to be able to add these without using the signal blueprint that comes with the other route and then the signals don't appear to work together. Is there a way to use signals from different routes?
