How interesting. I don't see why the reversal would matter as they reverse in normal times. Are they just doing it for consistency across the day,? Although even that would seem odd, as the staff will lose their competency to go to Gatwick Airport if they don't have any staff running trains there soon.Presumably this is a combination of low demand, the need to provide a guard, the issue with the reversal at Redhill and the use of Turbos between Reading and Bedwyn.
The government wanting TOCs to run more trains is a nice idea but if the TOCs don't have the staff, due to the pandemic, they just can't.
[Edit:: I reread the other thread again it sunk n that it's due to the stock use to run to Gatwick Airport being pinched and I assume other stock just left to gather dust near Paddington].
Yet despite all this GTR seem to be relatively unscathed and able to run a Saturday service. They do have a lot of DOO. I wonder if that helps?
