That's one the areas that does my head in. Newcastle is my perennial example of this actually! Just taking drivers you have driver depots for Northern, TPE, LNER and XC.
TPE drivers sign Edinburgh to Leeds, all LNER drivers sign Newcastle - London with a link that signs Newcastle to Edinburgh, XC drivers sign Derby to Edinburgh (via Leeds and Doncaster). Northern of course also signs parts of these routes as well (Morpeth to Darlington primarily). So you have four sets of TOCs with drivers who all sign parts or indeed sometimes basically identical parts of the ECML from Leeds/Doncaster to Edinburgh.
Yet because they cannot share resources they all have to make their own arrangements and depot establishments so that's extra costs right there from having to employ more drivers, to having more HR, etc etc. Plus if there's disruption they cannot cross cover so even if TPE have a driver sat around without a train because their train is stuck somewhere south of York and LNER have a unit in Newcastle but no driver because their driver is also stuck down south then nobody goes anywhere because the TPE driver cannot drive the LNER unit (which is of course even more farcical here because the units would be almost identical, I imagine the conversion course from an 802 to 800/801 is very very short).
It's this sort of maddening inefficiency that's baked into the system at the moment that you'd hope GBR would be tackling because there must be some fairly easy wins to be had at driver depots like Newcastle. Merging the four depots and then redrawing the link structure seems like it would be an absolute nailed on easy win for improving productivity, efficiency, value for money, reliability, etc. It might even make the job slightly more appealing as you could have much more progression. Join up as a trainee pootling around the North East but eventually you could end up driving trains all the way to Inverness! Whereas right now you want to do that you have to leave Northern and join LNER. Which means Northern gets to spend all the money training the driver but LNER will eventually be the one to benefit when they jump ship for a different challenge.
You could probably even reduce the overall headcount (through natural wastage and a temporary recruitment freeze) and still have a more flexible and useful depot establishment! Same issues of course exist on the guard side of the equation at Newcastle.
Crackers that anyone thought that this was ever going to be a sensible way to run a railway.
I agree - and without getting into too much of an argument about driver wages, it's a clear waste of staff who are on a reasonable salary - if you can only drive XC then your day is limited to either one return trip to Derby (around six hours) or two (around twelve hours) - but if you could do other jobs too then you could do a Newcastle - Derby - Newcastle and also a Newcastle - Carlisle - Newcastle too (around six hours for the Derby trip and around three hours for a Carlisle trip - which may be just right in terms of a ten hour working day - I'm sure someone will be along to correct me on the diagram durations etc, but you get the point that I am making - more flexibility would allow staff to be better utilised over a working day
Time and time again we've seen the "Provincial" TOC stretched because staff have been poached by the "Intercity" TOC (which requires lower subsidy and can afford higher wages), creating a transfer market where people only seem to move "up" but not back down again (and the "Provincial" TOCs have to increase their salaries to compete with the better remunerated "InterCity" ones)
But I don't know how much of this is:
1. The fault of privatisation
2. Unions wanting a better deal for their members, ensuring that staff require to maintain various competencies for route/traction knowledge, which makes it harder to allocate staff willy-nilly (sensible precautions re safety, sure, and I appreciate that modern stock is a lot more specialist and require more training on each traction type than BR days)
3. The natural consequences of a busier network with significantly more trains (i.e. there were so many staff and so many services that it was more natural that they'd be specialists on certain routes/ traction
Obviously privatisation will get the blame for most things on this Forum, but there are clearly examples within one TOC (and within one TOC depot) where staff didn't have the kind of "all round" knowledge that might have been commonplace in the 1980s (when there were fewer diagrams/ fewer staff/ fewer differences between the different types of stock)
I've mentioned before just how inefficient some staffing can be - there are a number of staff duties of awkward length or that involve the staff "sitting on the cushions" for long times/distances - e.g. the need for XC to run one daily service from Aberdeen to England takes around twelve hours and must be both an awkward length of round trip from Edinburgh to Aberdeen and back whilst also requiring a lot of the Craigentinny staff to be trained on it to ensure reliability - whereas if ScotRail operated that stretch of the journey they could interwork it with other Edinburgh - Aberdeen duties - I think I saw before that the GNER/ LNER (etc) diagrams for Inverness saw staff work an Edinburgh - Aberdeen service then sit on the ScotRail "cushions" to get to Inverness where overnight accommodation was provided so that the staff would then work the southbound Chieftan from Inverness to Edinburgh the following morning? Seem a lot of complication when you have ScotRail staff who could work the Inverness section and not need a room for the night on company expenses. Correct me if I'm wrong, of course, but that's how I was told it was operated.
