Why is it that the emergency brake is used if a train is in danger of overrunning a station platform? In my opinion it should be a full service brake application as there is no risk to safety of the line.

Emergency brake can be used at anytime the driver feels it is required. Don't be lulled into the word 'emergency'Why is it that the emergency brake is used if a train is in danger of overrunning a station platform?

It's valid to ask why it's a safety of the line incident. What's the hazard here?
What would happen after an event like this?
I witnessed this very thing happen a few years ago at Ashchurch. It was an XC 170, and it finally stopped a good 200 metres past the end of the platform. After a short period of time, the driver changed ends and then drove back into the station where he changed ends again, and with station work done off we all went towards Birmingham.

What is the risk then?There is a risk.
Because there is a risk.
What is the safety risk in this case?There is a risk.
Because there is a risk.
As already stated, the driver has made an error (assuming it isn't a brake failure or poor adhesion - and if it were it would obviously also be a risk) , and is not in full control of the train. If it was a red signal the driver hadn't stopped at, would you be considering that is not a safery risk?What is the safety risk in this case?
Could you perhaps provide a list of what incidents are regarded as safety of the line, and which incidents aren't, then?If it was a red signal, but it wasn’t...
I would hazard a guess that the reason most overruns occur is because the driver forgot to stop. So changing braking technique won't help The moment they realise they panic and throw the anchors onThe fact it says in some guidance that it is a safety issue is a reason for TOCs and indviiduals to treat it as such, but in itself doesn't explain why it is a safety issue.
There's actually a contrary hazard here - treating overruns less stringently than SPADs might lead the driver adopting a different braking technique for station stops where the platform starter is off (or there isn't one) and thereby help to reinforce the significance of the platform starter being on.

Ok, then. Drivers don't forget. They just misread their diagrams.Well you'd reason wrong. Very few overruns are down to total forgetfulness. The vast majority are down to something like misjudging speed or braking ability or an adhesion issue. On plenty of stock an emergency application will brake harder than in full service so will sometimes save the situation. Also, as mentioned, the people who put money in our bank accounts every four weeks say use emergency, so we use emergency.

Why should your opinion count?
In which case you're better off not putting the brake in and misreading your diagram insteadIf you forget to stop then you’re unlikely to remember until it’s too late to even bother braking.

An emergency brake application does not throw people around anymore than a full service application. The worst part is when the train actually stops, as the driver cannot ease off with the brake during an emergency applicationNobody has mentioned the effect of an emergency brake on passengers especially if any are standing. Would this not throw standing passengers around therefore would be a safety issue, but not as great as passing a signal at danger of course when I can see that a driver would want to do all he/she could to stop in time or mitigate the distance past the red to avoid potential derailment or collision? I ask because I do not know what the effect of emergency braking is these days!
If train is not slowing down as fast as desired due to greasy rails does emergency braking help or is it more likely to induce a skid?
