See what happens.
Hopefully, in the interests of guaranteeing socially distanced seating as far as possible, efforts will be made to get the booked type of train on as many workings as possible tomorrow.
One wonders, given the requirement for social distancing, how order of priority will be determined for northbound trains from King's Cross to Leeds / Newcastle / Edinburgh in the morning if numbers of passengers are unable to leave London tonight.
Could a situation arise where people booked on early morning northbound departures from King's Cross are denied access to give priority to people who weren't able to travel today?
