Double-track mainline, movement by signal indication, automatic train stop system in use.
Yard tracks on both sides of the mainline.
Yard crew on light engine moving westward on yard track with 5 crewmen ran past the fouling point of Tk. #2.
Train #2 ("National Limited" - 2 units [59-A & 59-x] & 13 cars) approaching at 80 mph on Clear signals; engineer observed the home signal go from "Clear" to "STOP" and made emergency brake application. Speed at impact (sideswipe) was 75 mph; both units and 10 cars derailed. No fatalities and only 13 employees and passengers injured.
Query: would PTC prevent this type of incident?
