US signaling (NORAC): Wayside and Cab Signalling on MBTA's Purple Train (TSW | tutorial)

Discussing NORAC signaling rules, the general concept of cab signaling and the Speed Display Unit (SDU) on the F40PH-3C before running a purple MBTA train down the North East Corridor.

Full MBTA service from Boston South Station to Providence in Dovetail Games' Train Sim World 2: Boston Sprinter, with a tutorial (12:22) discussing the NORAC version of US railroad signals, including the concept of a Cab Signaling System (CSS) using a Speed Display Unit (SDU), and a close look at the implementation of those concepts in the game.

I have this beautiful locomotive. This is an excellent implementation of this loco. In the beginning, the ammeter didn't operate correctly but suddenly they corrected it. Love this loco. Also, the sounds are excellent.

The yellow DS signs warn you of an upcoming "dead section". A dead section is an area of catenary with no voltage flowing through it. The black DS sign shows where the dead section actually begins.

Excellent tutorial. Thanks for putting in the effort. Too bad there are so many signalling issues on this route.
