From what I've read, the Newfoundland Railway was not signalled. The station master at each station would give the engineer a train-order to proceed to the next station. With often only one train per day, it would have been difficult to run into another train so this was not an issue.
So what is the best way to simulate this in Trainz? No signals at all, will the AI still function? Invisible signals to "fake" it in a way
