It should be a national scandal that these cuts are being driven through on 90-100% passenger numbers (on the back of the most unreliable service for decades).
There seems to be little real scrutiny of the Government over this.
I said ages ago that if we renationalised the railway, the Government would be less likely to invest in the railway but seek to cut costs - and that's exactly what is happening now. Sure, we haven't got true nationalisation, but not far off.
Covid obviously wasn't planned for in any predictions, but as workers are increasingly being asked back into the office OR have got sufficiently bored of working from home, the numbers of people returning to work is growing all the time. At the moment, more flexible working is seeing a drop on mostly Monday and Friday, or people being able to travel after the morning peak, but even that is likely to balance out in time.
Also, people who go to work/start travelling to work after 0930 may opt to return to an early start to get more time in the evening, and so on.
I do believe that Covid gives the Government the necessary ammunition to carry out the cuts though, and some will be brutal.
Perhaps now we can see how people accepted the Beeching cuts, being convinced that the car was the future of travel, as now they accept the cuts on account of a perceived reduction in usage that will likely recover if given time.
Once people go back to the office more often than not, season tickets will become popular again, and peak tickets will be sold more when people don't wait until off-peak to travel. That may not happen immediately, but I think we'll see a shift within the year.
Oh, and also what I've said before, a reduction in fraud with e-tickets and the like (refunds and short faring, or only buying a ticket when seeing staff etc) may also see a positive uplift. As TOCs and the Trainline each start to use their data to clamp down, I don't think we can underestimate the scale of the problem.
