Is that 41 years working on trains, or travelling on them?
In my 41 years I've been - amongst others - a Shunter, Goods/passenger Guard, conductor guard, station supervisor, TOPS clerk, enquiry and reservation clerk, T.T.I. (precursor of revenue protection), operations instructor (shunters, guards, signalmen) guard's inspector, area inspector (precursor to MOM) assistant station manager, station manager, relief manager, platform operations controller. There are several others but I think that I've made my point in that I really do know what I'm talking about.
Well, Guards do have enough first aid training to put a bandage on a head. It's not rocket science. If there was a Neurosurgeon or A&E consultant on board, it is pretty-much all they could do in that scenario.
A driver collapsing scenario is not endangering the train to a large extent - it will delay it, but that's a different scenario. That's what the various safety systems in the cab are there to mitigate, and the decision was made many years ago that one Driver was all that was needed.
I agree that some of the traditional Guard roles have gone (as some Drivers roles), but the basic role of "Guarding the Passengers (from themselves)" is still there, and still required. I do agree, this message is not getting across as well as it could, through a combination of misleading statements from Management, and inerta from the travelling public.
It's more from a p155 poor communication from the RMT who made the usual union mistake in harping on about how much the company and it's management were earning/being paid. The public aren't interested in that, all they want to know is why the fuss about taking away a member of staff that other trains and TOCs can manage without is being made. I haven't mentioned that the entire LUL network is run DOO. Richmond to Barking isn't a short hop and neither is Epping to Ealing Broadway.
Most of a Guards duties are low-key, and for this reason, are not recognised - indeed, on a lot of trains, are not needed. However, once they are not there, then they will be missed.
Personally, I think that if Guards agreed to work for minimum wage, this desire to remove staff from trains would not be happening - it is cost-led (backed up by McNulty), and how many posts on this thread are indirectly objecting to our wages?
