What is more important PPM or safety?
Obviously its a balance, it would be more safe to run trains at 10mph but that doesn't mean we should do it!

If the OBS is the way forward then it should be legally required for one to be on every train or it doesn't run.

I have heard rumours that social media is being looked at by Southern.

If some people switch from cars to trains because of improved reliability and punctuality then any slight worsening in train safety would be outweighed by fewer car accidents.
Great logic,
So if a passenger is injured/killed on the railway we can just turn around to their family and say they would've been equally worse off if they'd stuck with travelling in their car instead.
Yep, instead of making society a safer place where practical we should aim to continue to injure/kill just as many as we do now, purposely reducing safety on the railway to keep the populations injury rate static.

If making the railways more reliable takes people from a less safe mode of transport to a greater then there would be an overall gain, providing that the changes don't make the railway less safe to the degree that there is no net gain. There is an unwritten assumption to this effect in what he said.
What it does not suppose is that he would say anything of the sort to the family of a passenger who was injured or killed; nor does it follow that he wishes to purposely reduce safety to keep the injury rate static - in fact that's the exact opposite of his proposition. This is a well-known logical fallacy known as a straw man and you managed two of them in a short post. Congratulations!
But the change in percentage of either metric would be negligible, if identifiable at all. Practically it seems like a non argument, logical or otherwise.
Ah, to you or me that might be true. To the DfT...

No, there is no balance.
PPM can go piddle up a rope if achieving it isn't safe.

How safe are we talking? One in a million chance of something going wrong? One in a billion? There is no way that the railways can be absolutely safe, with zero chance of something going wrong.
No. But we can run them as safe as possible. There is a reason in the UK something like a trap and drag or crossing collision is really the most serious incidents we ever see. There is a reason we don't see crashes like the recent ones in Germany and Spain. Or the regular runaway and derailments in North America.
You could claim the we, as an industry, are obsessed with safety to a fault. Feel free to think that. You could suggest why keep a second safety person on the train when one is (barely) adequate. We can't prevent every possible accident. We can mitigate against them. The second safety trained person on a train is exactly that mitigation. It means when something goes wrong it is more unlikely that the people who know what they are doing are incapacitated.
I ask again. Southern want DOO on the Brighton Mainline. You've been in a crash, linespeed and direction of travel is unknown to you. The driver is dead, the fire is taking hold, the signaller has no idea anything has happened. When is the next train coming? Which direction? Which rails and cables carry a fatal 750V? Which don't? Which rails can move and crush your feet? Where is the nearest position of safety? Are you confident you can get off alive, alone?
Excellently put.
If only the RMT put that out as a potential scenario then they might get somewhere.
Put barriers on cinema doors and everything else you say can be made to fit cinemas, except that there is less potential for people to do stupid things and kill themselves in a cinema
But I really do think my post regards to the conductor costing pence per journey per passenger was a very poignant point and is something that the unions should look into in more detail (If I do say so myself)

I think for the customer, the most important thing to them is that the train runs on time above all else.
Hence they might feel shortchanged without a guard and the service that brings (but most will likely not give two thoughts). However if the train is delayed or cancelled, they will be downright angry as it impacts their plans and they expect their trains to be on time. I don't believe the presence of a guard or OBS will offset to them the anger or inconvenience of a delayed or cancelled train.
There is a hierarchy of customer demands on a journey and I would say 'running on time' is at the top of that hierarchy.
So your saying we should have never been allowed to run trains for a 100+years pre CSR (introduced primarily for DOO) on this and other lines where in your given Scenario the second staff member assuming they're not injured could have easily been at least a mile or more away from the nearest point to communicate information to the signalman anyway![]()

Just watch the latest Red video, the one that's now banned.
That's the biggest anti-DOO propaganda out there, promoted by the powers that be, right up until they realised what they'd done.

What, the unknowing driver suffering a self evacuation after a fire when a kid was killed by a train on the adjacent line?
Ladies and gentlemen, DOO.
The issue is that whilst the cost per passenger mile might be extremely low the number of passenger miles is extremely high and therefore the end saving is significant.

OK, so the average punter is aware of detonators and TC clips then? They're all trained in emergency protection?
Perhaps they should be told then?Of course the average punter does not know what these are. As the average punter doesn't on all the services that already run DOO or with a Guard
As I mentioned in a previous post the cost to Southern of employing guards in salary benefits pension employers NI etc I expect is around £21 million pounds even if it was double that figure, it pales into insignificance when considering the subsidy paid to the railways is nearly £5 billion. Plus also it was rightly pointed out guards make money in ticket sales.
Not disagreeing with you at all. The problem appears to be the DfT believes they can get someone cheaper to do the ticket sales bit and they don't need someone to do the safety related bit. Yes I know initially the OBS won't be cheaper as they'll be converted conductors, but in time they will be cheaper.
Incidentally on this note has there been a reduction in revenue protection officers over the years? Used to see them maybe once or twice a month, now never see them.
