I'm afraid I can look back to the time when rail staff all pulled together to run as complete a service as possible in poor (but not unprecedented) weather. For example, in the bitter winter of 1962/3 we visited from Somerset relations in The Wirral, about 1/2 mile from the 3rd rail electric line. Where you got
for months, apparently. So they just ran ecs all night. We could see the arcing lighting up the sky from the house, and were told it was "normal" in winter evenings but now they were running all night (my Somerset mother, incidentally, told us children that it was the Northern Lights in the sky, until corrected ...). Such an operation wasn't even regarded as heroic, it was just sort of expected that they would do so, done on overtime. Not only the train operation, but the signalboxes needed opening as well of course. The next morning, the peak service ran precisely to time. No trains out of action. No need to get the car out, which is what everyone has to do today.
Now we have this wonderful excuse of "Waaaah, we had a problem at Lewisham some years ago, someone got criticised, haven't done anything about it so let's just start shutting things down". Sorry, those of you directly involved, but that's just how it comes across. Have you seen the snow around this morning in outer London? There's hardly enough for a snowball.
Are you suggesting workers are not doing all they can to run some semblance of a service?? I can tell you for a fact there are 100's of people across the network doing just that...driving through challenging conditions to get to problem areas to fix what ever has gone wrong. To suggest otherwise is out of order...but we all know you are blinded by your rose tinted glasses.
