There are plenty of Tutorials on starting and stopping a locomotive, but it would be good to have more tutorials for understanding signals/track signage etc - Particularly for American Signalling. I downloaded the Northeast Corridor pack but have only played it about 3 times, as I do not understand the meaning of some of the signals, in particular on approach to New York around the bridge area the signals are circular "flower" type signals, I have looked on You Tube and other places but cannot find a definition of what they mean. It doesn't stop me from completing the scenarios, but I dont like "winging" it to see what wil happen!! If there are manuals explaining the signals, I do not know where they are.
