Often, I don't know why we have come to a stop or is running slow. I have to walk at least four carriages in either direction to get to somewhere I can talk to a driver, to find out if they have spoken to a signaller. I have to drop whatever I am doing at that time to do that. If the train has started moving by the time I have got to the Driver/guard comms, (no matter how slowly) I am not going to contact the driver, as that will mean him having to bring the train to a stop again.
Sometimes, when there is disruption, it is fluid, with my main source of information being messages over a Blackberry that may or may not be able to pick up a signal. Those messages may be vague, as sometimes that is all that there is. Sometimes we may have got past the problem before it even comes out on the pager.
I'm not saying communication is good enough, just pointing out to some of the armchair experts that it can be complicated.
Another point is that one persons brush-off is someone else's too much technical jargon.
We are held up due to a track circuit failure ahead. Do I say
1. "Sorry folks, we have a Track circuit failure ahead",
2. "Sorry folks, we are being held because of a Signalling fault" (which it is, a signal is red for no obvious reason)
3. "Sorry folks, we are currently being held by a track circuit failure, what this means is that the automatic system that detects whether a train is on a certain piece of track is showing a train where there should not be one. This has put the signal to red, which means that the driver is not allowed pass it without special authority which can only be given after several different scenarios have been ruled out. This may be due to a broken rail, a member of staff initiating an emergency stop for this train by putting down track circuit clips which initiate an emergency system, it may be due to some large metal object like a bin or a bench blocking the line and completing the circuit, or it may be due to the preceding train on that section of line coming apart and leaving a carriage behind. It might also be due to a lightening strike shorting out the electrics on that system, damage to the signalling cable either by rats chewing it, Network Rail contractors digging in the wrong place, or thieving little gits cutting it to nick it and sell it for scrap. Or it might just be a blown fuse. As soon as I find out which scenario it is, I will be able to inform you"
