The transpennine extended dates of travel now include Wednesday 18th .
Yes, and as I mentioned in entry #20 upthread, this Wednesday I am booked to travel from Manchester to Glasgow on TransPennine. At the moment the National Rail, TPE and Avanti sites are still saying Glasgow Central high level will be closed at least until 23.59 on Tuesday, and the ScotRail site is saying it will be closed at least until Wednesday although it's unclear whether that means up to and including Wednesday or that they are hoping for at least a partial reopening on Wednesday.
But I used the LNER app to book my tickets, and the app has notified me that my journey has been cancelled, and is offering me the option to either rebook my journey or claim a refund. I'm guessing that this means LNER and ScotRail know something that Avanti, TPE and National Rail/Rail Delivery Group don't, or just that the latter three haven't got round to updating their websites yet.
This is probably just speculation, but my guess would be that when the high level station does start to reopen, whenever that may be, it will be a phased reopening with longer distance services being given priority over local services, and maybe Avanti services will resume first?
