221132 Emergency Stop

Title says it all really. Not my video but I came across this on youtube.
I thought it was a pretty amazing clip and hopefully you'll agree!

i should guess the reason why you can see the smoke so much is because it is a cold day, and those brakes will be hot!!! and the smell will be like burning rubber, it actually looks like steam but thats just what i think, been in this heartstopping situation myself and it's not pleasent at all.

 

[schenker]

I guess a good mixture between steam and smoke. It is pretty reassuring
to see how effectively EMG stop can actually bring the train to a full stop.

Sounds a bit unhealthy on the pull away or is that just me?

 

[westcoaster]

sounds like the rear coach is just idleing, also at about 1:38 you can see some tpws grids if that signal had gone back to red as said, then these would have set of as well.

I am thinking all those p-way guys are there for a reason, track fault, track circuit fault, points problems, which all could have caused that signal to go back to red.

Love the way it said signal failed more like the driver SPAD.

 

[westcoaster]

Trust me if that driver had of had a cat A spad that train will of not been moved till a new driver has relieved the other.

There are 4 types of spad

Cat A caused by the driver not stopping at the red.

Cat B caused by signal reverting to danger because of technical faults, not receiving correct signal aspects I.e green to red caused by human error, track circuit failure.

Cat D runaway stock iirc, or stock not stabled correctly

The other one has slipped my mind but if O L LEIGH comes by here I'm sure he might know.

I read back some of the older comments, The guy who uploaded the video thought
I was due to a cable being cut that caused the red.

 

[The Snap]

So the previous aspect must have been green or double yellow for the driver to be proceeding at the speed he was doing?

I bet he sh*t himself when he spotted the next signal was red! :roll:

The missing one you are looking for is "Cat C" - Signal Passed at Danger wher the signal was replaced to danger in an emergency in accordance with the rules.

Quick SPAD category aide memoire:

Cat A: The driver was an arse.
Cat B: The signal was broken.
Cat C: The signaller was a c***.
Cat D: The train ran away downhill.

Basically, Cat A is the driver's fault. Failed to correctly respond to cautionary aspects, going too fast, all that sort of thing. Cat B should be self-evident. Cat C is because the signaller deliberately put the road back in front of the driver but the driver couldn't stop in time. Cat D is, as Westcoaster surmises, a runaway or similar.

I've had a Cat B myself and it was probably one of the most frightening moments of my life. The signal was on a bend so had been provided with a banner repeater. All preceding signals were green and as I approached the bend I could see the banner repeater was "off". Went over the AWS magnet and got a "clear" indication. In the second or so it took to get from the magnet to seeing the signal it had reverted to danger. I was doing the full linespeed of 60mph at the time and was a good halfway up to the next signal before the train pulled up.

I nearly had a Cat C also because the signaller had put the road back but not in accordance with the Rules. The signaller is supposed to contact the driver, explain the situation and request that the road be taken back before reverting the signal to danger. The only exception to this is if it's an emergency when he can revert first and answer questions later. On this ocassion it wasn't an emergency but he'd just flung the road right back at me while I was sat at a station where the 8 car stop board is right up at the signal. I almost went by the bugger before spotting it and throwing out the anchor and coming to a stop with the first of the TPWS grids underneath the coupler.

The first part of your Cat C explanation is actually the second part of CAT B (CAT B has two items).

CAT A - A signal passed at danger where preceeding aspects were displayed correctly to give the driver suffcient time to stop normally.

CAT B - A signal passed at danger do to either....

A) Failure of level crossing or signalling equipment
B) Signaller error

CAT C - A signal passed at danger where the signal has been replaced in an emergency in accordance with rules.

CAT D - As said previously, deals with runaways etc etc. Though if the move is being propelled and not within regulations it will be treated as a CAT A.
