Let's face it, the rail service is in a semi derelict state and has been for as long as I can remember. As someone who used to commute regularly I have lost track of the number of times I have ended up sitting on my briefcase, on the floor, simply because there was no where else to sit. Plus the number of times when the train broke down, rails broke, signals broke or any number of other delays. There seems to be a collective folk memory, much like people telling you " in my day, we had proper summers" of little Choo choos puffing contentedly along pristine tracks all three quarters full of smiling commuters. I don't think it's ever been like that. And with a rising population, greater centralisation of jobs into the major towns and cities it's only going to get worse.
Yes, indeed what was nostalgically regarded as the best commuter pre nationalised Southern Railway had serious passenger complaints almost from the day it was set up. We still haven't solved the morning and evening peak issue rather as you imply, it's just got worse.
Ironic really, with today's ability to properly work at home round the clock and the IT lead shrinking of the old monolithic business enterprises, why do so many still need to flock to node towns every day within a fairly rigid time bandwidth?
The next revolution?
