I realized that I get no response when contacting signaler on the two free roam switching scenarios for both SPG and Sherman Hill. Works when I do timetable services though. Is this a well established bug or am I missing something?
It's not a bug: you have the freedom of the switchyard - all manual - but you can't venture past the exit signal onto the mainline. Secondarily, "contact dispatcher" works based on your train having a path to its objective. But in the free-switching scenarios there are no objectives and no paths.
You know, I’d just about come to that exact conclusion right before reading your reply, and realized it was foolish of me to think otherwise… I actually wanted to find a way to assemble long trains and now realize I can just switch to the adjacent track to make room when pulling out of the siding, instead of trying to continue onto the main line past the red light. Thanks for your reply.
