When are the railroads going to install ATC on the engines.
When they can get the money to do so.When are the railroads going to install ATC on the engines.
PTC (I assume that's what you mean here) is not yet in place on this stretch of track.I am sorry but after such a bad crash I don't like jokes. How good is PTD if accidents happen.
This is the kind of stuff that makes me wish the internet hadn't ever been invented.Perhaps your right but if the engineer has to touch a lever every 30 seconds perahaps the carnage will stop.
Correct. That is what will happen.Excellent. I would like to add some chaff with another question. The famous "overspeed" switch. I've asked the question before about how P42's can operate on the SWC if the max speed for the rest of the fleet is 79. That question was answered with a box that allows up to 90 MPH. But then my question becomes, if (in SWC territory) the max speed is 90 MPH, the P42 will obviously stop the machine if that number is exceeded for more than a moment or two. In theory, then, are there parts of that route that are limited to, say, 25 MPH in a yard where the loco won't care if the train hits 90 MPH because that is the limit set?
The specific PTC in question on the NEC is the combination of the coded track circuit based signal enforcement together with the ACSES based civil speed enforcement. In that setup, yes, speeds on curves, which are civil speed restrictions, will be enforced.I've heard over and over in this forum how it's nearly impossible for an engineer to overspeed a train - that it will put the train into emergency when the train goes too fast. The regulatory PTC isn't fully implemented yet, and my understanding is that is supposed to keep trains from colliding or fouling a red zone. Will PTC (or any variation of it) prevent overspeed around a curve, or how about even speeding through a temporary slow order?
We have had that much faith in our Engineers (both for signal enforcement and civil speed enforcement) since the inception of railroads, and it has been remarkably safe operation even in spite of these occasional glitches. The automation systems are basically being put in place to reduce the chances of such accidents, which is already very low, to even lower level and possibly eliminate them altogether.Many of these have been in place without PTC, though with the various entities involved the standardization is probably non-existent. Even without PTC, there should have been some sort of safety mechanism to prevent the train from overspeeding through that curve. Or, do really have to have that much faith in our driver?
At present I don't know what signal indication is given at Shore for an eastbound train. It is probably a Clear, which leaves it to the Engineer to obey speed limits as documented in the employee timetable.
