And I repeat, the fleets until recently were sized for ordinary business, therefore they should not be withdrawing them without replacement.
They still are sized for ordinary business.
On the East Midlands route, they brought in 360s, which transferred Wellingborough passengers and added more capacity at Bedford and Luton, which allowed the HSTs to be withdrawn.
The question I have is why relief services weren't contracted from St Pancras, they clearly would play a useful role in moving people compared to the random recent examples where NR has shelled out for spot hires and carried next to no-one.
There was no doubt plenty of capacity on the 700s downstairs at St Pancras. One of the problems with adding more services on the MML is finding a reasonable path for a relief between 125mph Meridians, 110mph 360s and the Thameslink services.
As you say, the designated relief trains put on recently have often ended up empty. It is a difficult call to get additional capacity in the right place at the right time.
So how was the railway able to keep large amounts of stock for peak demand back in the days of BR? Why was it seen as politically acceptable then and not now? These were in the days of Thatcher, no less.
Isn't that just rose-tinted spectacles on just what spare stock was available for peak demand?
One part of it was running locomotive hauled trains on NSE routes for weekday peak demand which could then be used for relief trains at the weekend. That obviously stopped in the early 1990s just because that stock was replaced.
Unfortunately, as you know, you can't just stick a locomotive on the front of a 700 and run it to Sheffield.
