Glad you’re safe. The newest pictures show it is a disaster. I too hope casualties are minimal. Good luck on your trip home tonight - hopefully something will be worked out for all the return evening commuters.
One confirmed fatality.
If the valve that vents the high pressure air that keeps the brakes off was boogered so it couldn’t dump pressure,
When the train brakes are applied during normal operations, the engine operator makes a “service application” or a “service rate reduction”, which means that the train line pressure reduces at a controlled rate. It takes several seconds for the train line pressure to reduce and consequently takes several seconds for the brakes to apply throughout the train. In the event the train needs to make an emergency stop, the engine operator can make an “emergency application,” which immediately and rapidly vents all of the train line pressure to atmosphere, resulting in a rapid application of the train’s brakes. An emergency application also results when the train line comes apart or otherwise fails, as all air will also be immediately vented to atmosphere.
In addition, an emergency application brings in an additional component of each car’s air brake system: the emergency portion. The triple valve is divided into two portions: the service portion, which contains the mechanism used during brake applications made during service reductions, and the emergency portion, which senses the immediate, rapid release of train line pressure. In addition, each car’s air brake reservoir is divided into two portions—the service portion and the emergency portion—and is known as the “dual-compartment reservoir”. Normal service applications transfer air pressure from the service portion to the brake cylinder, while emergency applications cause the triple valve to direct all air in both the service portion and the emergency portion of the dual-compartment reservoir to the brake cylinder, resulting in a 20–30% stronger application.
The emergency portion of each triple valve is activated by the extremely rapid rate of reduction of train line pressure. Due to the length of trains and the small diameter of the train line, the rate of reduction is high near the front of the train (in the case of an engine operator-initiated emergency application) or near the break in the train line (in the case of the train line coming apart). Farther away from the source of the emergency application, the rate of reduction can be reduced to the point where triple valves will not detect the application as an emergency reduction. To prevent this, each triple valve’s emergency portion contains an auxiliary vent port, which, when activated by an emergency application, also locally vents the train line’s pressure directly to atmosphere. This serves to propagate the emergency application rapidly along the entire length of the train.
I am in this beautiful station at least twice a week.
NOT TODAY!
The commute back thru Penn is going to be a total mess!
FoxNews now reporting, at least one fatality, many critical.
One fatality, extreme confusion. Everyone is now off of the train. per Faux News. That was no ten to fifteen mph. No way.
Yes, and I have believed authority figures my entire life such as De Blassio...
All that information went right over my head. Is there a back up system that would stop the train if the conductor was incapacitated? Any built in fail safe and/or back up system?
Our older son is a union carpenter working in Manhattan and he takes the NJ Transit line into the city. I texted him a heads-up that his travel plans coming home will be severely disrupted.
He starts work at 5 am so I was not worried about his well being.
Just a guess, but NJ Transit will probably provide bus service to other stations.
Joining you in prayer.
That picture shows the train didn’t hit the building, which is an architectural classic, probably a hundred years old. All the stuff that fell on top of the train is a hundred year old roof over the trains. Structurally far less serious than hitting the actual building. Mostly old I-beams, glass and plaster.
That’s correct.. those Jehovah Witnesses are always standing right there... at the top of the stairs from the PATH below.
What a disaster !
I know the station very well, have traveled through it for over 20 years.
It looks like the train came in fast, but not insanely fast. The track involved was in line with the northern-most entrance doors to the waiting room, near where the ticket booths are. From what I can make out in the pix, the train jumped the end of the line and one car crossed the platform. It removed a support beam and that resulted in the partial roof collapse. It seems the car miraculously stopped inches short of the wall/entrance to the waiting room.
WOR radio now reports 3 confirmed fatalities.
