If closing the doors isn't in the driver's JD then they don't close the doors. The train ain't going to move very far with all the doors open is it?
Opening the doors is also not in their job description at most tocs that operate with guards . So the train will be running but the doors wont be opening at any stations
The guards role was traditionally a safety one, therein lies the conundrum for the modern railway.
And the guards role can be retained as a safety critical role whilst also encompassing other duties . Guards never used to perform revenue duties , now apart from tocs with non comercial guards guards will engage in revenue duties .
Most people accept there is a very small possibility of a freak set of circumstances that may conspire to create more danger to the train. Unfortunately, statistics, facts and safety cases are not on the side of the retention of guards to prevent accidents.
Funny that because recently there have been a number of incidents at the platform train interface that have led to or had the potential to lead to death or serious injury . Including one which is resulting in a guard being prosecuted
What statistics are you privy to with this reference anyway ?
Firstly, most guards, during their career will (thankfully) never carry out emergency protection. This only occurs in very exception circumstances when then controlling signalbox cannot protect trains.
You are right most guards or drivers for that matter will not carry out emergency protection . However many guards I know including myself have given that all important 1 on the buzzer which has stopped a potential serious incident from occurring and quite possibly saved someone from death or life changing injuries .
In other words, in monetary terms, providing guards does not offer good value for money/greater safety on todays railway, in fact may even diminish it in an overall context. They may have more of a commercial case taking on other roles.
So me in my role as a guard
Collecting 3-4 times my annual salary in fares , as well as loading wheelchair passengers on and off the train , stopping a serious PTI incident from occurring ,Summoning police assistance when a number of drunk football fans decided to start smashing a train up . Is not providing value for money to my TOC .
lets think about just the claim arising out of a serious PTI incident , how much would that cost the TOC in relation to my salary ?
At the very best the safety/performance gain is very marginal, easily countered by enhanced DOO as a result of providing pass-com communication to controllers as well as all staff (safety critical or not) could carry panic alarms with GPS co-ordinates or mobile triangulation. Dwell times tend to be increased with guard operation, and the need for guards to operate doors takes them away from commercial duties.
Care to substantiate your claim that dwell times increase with guard operation . Just today I managed to reduce dwell time at a station by signalling to a passenger to step behind the yellow train and away from the train whilst It departs .Not something a driver in a cab would be able to do as easily .
More to the point railways are a very controlled environment, signallers are in charge of safety of the line. Conversely, the bus industry has one person in charge of boarding, fare collection, driving, on roads that for the most part do not have controllers. Although like the railways do have a service controller to assist during incidents. Even so, the bus industry has a very similar level of passenger safety to rail.
Few guards on this forum can post a situation where they have become involved in full train protection, because it is a very rare occurrence. This is why DOO-P works in the heavily trafficked London and the SE, with little or no degradation in safety standards.
.
Railways are very controlled when everything is running smooth , however to the untrained passenger when something has gone drastically wrong they can be a very dangerous environment .
This is why your bus industry is wrong , nobody needs a qualification to walk down the road , which is what busses run on . But you do need to be qualified and examined for your competency to work on or near a railway line .
As for DOO-P working in heavily trafficked london .How will it work on rural branch lines with masses of unmanned stations with old stupidly low platforms and being miles away from anywhere .
