This morning was definitely one of the most interesting experiences I've had on the Subway. As most of you have already heard, this morning at 10:20 AM a Southbound 
train railroad south of 65 Street derailed. Many people were on that train (over 1,000 from what I hear), a few suffering injuries probably from smoke inhalation.
First off, I would like to thank the many Firefighters and other emergency service men who were swift and courteous to passengers evacuating the train. As this was the first time I ever had to evacuate a train that was not at a station, I would say the firemen handled the people extremely well. I would also like to thank the train crew who did not make people panic and made sure help arrived as fast as they could.
I'd also like to thank the passengers who were on that train (or at least in the first car) as I didn't see anyone panic or flip out. Everyone did seem to be frustrated and wanted to get off, but were not out of control.
Anyways, as I was on the train firsthand, I would like to share what happened. Here's what I wrote down after the train went BIE:
10:19 AM The Southbound train leaves Roosevelt Avenue
10:20 AM Right after 65 Street on the fastest part, the train goes BIE (Brakes in Emergency). The lights were flickering and the track kept making banging noises, probably the stop arm reacting.
10:21 AM Smoke appears in the tunnel.
10:24 AM T/O and C/R are on the intercom, and there is a call for handbrake. While I was overhearing the conversation, they were saying how the train may have been pulled apart (though it wasn't). The C/R goes onto the intercom and tells passengers to remain calm.
10:32 AM C/R announces that there will be a rescue train coming
10:36 AM T/O comes into last car and announces that the train has derailed and we'll be stuck here for a while.
10:39 AM The Fire department arrives.
I ceased taking notes after that since I had to stand up, but here is what I remember:
> Two passengers made their way to the front and were sat down and given oxygen.
> They were first going to send the rescue train from behind my train. They then decided they were going to send it on the Northbound express track, except there was a wall in the way.
> Eventually it was decided that they would evacuate via the emergency exit, of which they did.
> I was one of the first people to evacuate and climb down onto the roadbed, where the Firefighters were swift at getting people down the ladder, over the rescue board, then onto the roadbed.
This was the set involved:
SOUTH 5742-5743-5745-5744=5634-5635-5637-5636 NORTH
I overheard that the second and third cars may of had damage, which were 5743 and 5745.
It took and hour to first start moving people out of the train. When the train went BIE, it was like something out of a horror movie. The train stops dead silent and the lights keep flickering / tracks making noises. Then the smoke appears.
Of course, I decided not to bring my camera with me that day since I knew I wouldn't need it. I did have my phone with me and took one picture of inside the train with all the people waiting to evacuate. Almost everyone was taking video with their smartphones, but were told to put them away when evacuating the train.
If anyone says something different happened, tell them to read this since I was there firsthand. It was an interesting experience and will probably never happen again (then again, you never know).
Here is the one crappy photo:
Thought I would give an overview as to what happened since I was there firsthand. If anyone says anything about speed being the factor, that is a likely cause since the train was going as fast as it could past 65 Street down the hill. Then again, I have had many other trains in that area go that same speed and nothing happened, except they slowed down for the timers after.
Once again, a thanks to all who helped and condolences to the people who were traumatized or hurt in the incident. Now hopefully they will clean up fast since it's going to be a mess during Rush Hour...
