Of course, at least in CTC territory, an improperly lined switch would have turned signals red, thus preventing this accident.
The only “electric” brakes that I know of on a train are the electric over air systems, but they still depend upon the air to do the physical work of setting the brakes. If they had a dead engine, then maybe the air just bled off. From what I read, this was a one man crew. Kind of makes you wonder if a second person was on the crew the correct securement tests might have been conducted, thereby preventing the tragedy.
CTC doesn’t stop a train, or prevent one from moving. All CTC does is give both authority to occupy the main train, and provide correct train spacing. Now with PTC (Positive Train Control) a restrictive signal would slow and stop a train down if the engineer wasn’t responding to the signals. But this accident was about a stopped and parked train. Neither CTC or PTC would have worked in this case, plus being a shortline RR, I can imagine that the track control was TWC (Track Warrant Control). TWC is just another type of ‘authority’ to occupy a main track.
ECP brakes are a new braking system that is not in wide spread use. ECP brakes allow for faster sets, and releases as an electrical signal is sent to each rail car to set/release the brakes, instead of using air to send the signals. ECP is another expensive beta technology that is being tested on a limited number of equipment.
