Was that a deliberate swerve, or did you simply miss the point?Do you think British Rail was subsidized at all?
British Rail didn't have a 12-person board presiding over 200 staff working out who was to blame for delays, so that TOCs can send money back and forth between them. 75% of train delays are because of other trains being delayed.
So if a train in the South Wales valleys was delayed last Tuesday, that means someone is working out if that was because a GW train was late, which delayed a freight train, which delayed the TfW local from Barry Island, and it was all because points failed at Swindon, and was that because the private signalling contractor was at fault?
Under BR my guard on the delayed Manchester train could happily announce it was "due to the incompetence of the staff at Euston" and it would still be BR's fault. Whereas now staff are letting trains go without waiting 2 mins for one TOC's connecting train because their company doesn't mind inconveniencing the other company's "customers" and they'd rather the other TOC paid out for an hour's delay to passengers. I'm not sure who gets charged for delays when someone throws themselves under a train.
And don't forget it was private contractors' track maintenance failures that were blamed for the fatal Hatfield crash. Thankfully, that has meant the railways do now have an excellent safety record, with the only passenger death in over a decade because of a landslide (though Network Rail admitted contributory failures).
Of course, the obvious success of nationalised railways is the European railways subsidising their fares out of profits made running British franchises subsidised by British taxpayers.
