If the emergency brake application causes a derailment, something that can happen, someone in between cars could very easily be ejected or crushed, either of which could lead to their being killed.
I'm aware Alan, but the OP was not talking about an E-brake. They were talking about what sounds like an automatic application of brakes after an air pressure malfunction caused by a tire. To me it sounds tike perhaps the computers detected a malfunction in the air hose and shut down the mortors and/or applied the dynamic brakes.
Knocking out an air hose is an E-Brake application. About the only thing that might be different between the engineer hitting the kill button and dropping an air hose is that the engines dynamic brakes might not kick in with a broken air hose. And I'm not positive about that either, I don't know how the computer reacts in that case.
I understand if there were a derailment, but VentureForth said about their experience on the TE that had someone been in between cars it could have been tragic. I was just curious if something happened in particular during that incident that would have made between cars particularly dangerous. I would think standing anywhere on a train during an emergency stop could be dangerous, just did not understand why VentureForth felt being between cars would have been even more so during the TE incident.
Well the description I read, and you read-- did not sound like an E-brake application. I don't remember ever hearing about a train having a rapid deceleration from speed that didn't make any noise or whatnot. IF this was an E-brake application or an engineer hitting the kill switch then the train was not at speed.
No...the engineer does not have a screen to show where a "big-hole" occurs. The conductor just might be able to tell if the handle is still in the down position after having been pulled.
Oh wow okay thanks I wasn't sure if it has a sensor like the doors in commuter cars do. So they can't tell car 6 back of the car E-Brake pulled. Although I'm not sure what that data would do to help.
Well you hit on a subject that the freight RR's would love to have the answer to. If a 150 car freight train goes into emergency with just a conductor and engineer on the head end it would certainly help the crew in their efforts to get rolling again if they knew just where the problem is located. We had done some research on this for haz-mat handling to determine if an emergency application was caused by a derailment (which could require protective equipment) or train line failure. The RR's backed out when the costs went up when they discovered that every freight engine might have to be equipped with protective equipment.
If they reset the handle nobody will know the difference.
:lol: Of course the cost out stopped the solution from arriving I agree though that its silly to have info for everything except where a train went into Emergency.
On more modern trains were the emergency handle is often just an electrical switch which breaks the continuity of the brake control circuit, its very easy to have that displayed on an in cab display panel.
Some of the freight railroads here are indeed working on implementing ECP brakes, which are activated by an electric circuit rather than trainline reduction in pressure. Slow going, though, and currently limited to unit trains where the train makeup is rarely altered.UP is currently running one such train as a test project. So far everything that I'm hearing is positive.And Neil, stop bragging about your modern trains!
I can't find one thing silly about knowing that this a leaking chlorine car in the downtown of a major city.
Yes, but this is coal service trains that seldom get busted up or switched out. The engineers love them because the brakes set up and release much like an automobile not like the old ways where each car released in turn like a stack of dominoes.UP is currently running one such train as a test project.

Actually the train that I was referring to was an intermodel train that runs between LA and Texas. It just got a small write up in the January 2009 Trains.Yes, but this is coal service trains that seldom get busted up or switched out.

I asked my son, who worked at UP Houston yards (until recently). about this train and he said there was no regular train with these brakes that operated on a daily basis. Must have been a test run. I'll see where it is now but I suspect the Chicago-LA corridor will be the next proving ground.Actually the train that I was referring to was an intermodel train that runs between LA and Texas.

You might as well speed through Hazzard County at 100 mph plus as opposed to pulling the air on ANY train. It is a Federal offense to interfere with interstate commerce and there are a few people in Federal prisons regretting their one pull on the handle.
I am 100% WRONG and Alan is 100% right as usual. Too bad I don't have a fez~ I'd have to eat it. I STUPIDLY ASSumed the train Alan was referring to would run to Houston's Englewood Yard. Wrong, brake shoe breathe!#$%^& The trains do run to FORT WORTH. Now, I'm going into the closet with a bag of Oreos and a gallon of milk. I'm not coming out until the end of October!#$%^&*(I asked my son, who worked at UP Houston yards (until recently). about this train and he said there was no regular train with these brakes that operated on a daily basis.

h34r: h34r:IIRC NS has 6-7 coal trainsets that they use ECP brakes on, I think the hold-up on conversion is pulling an entire set including locomotives for retrofit.I am 100% WRONG and Alan is 100% right as usual.
