This is the Cross City Line which runs from Lichfield Trent Valley in Staffordshire, through Birmingham city centre, and on to Bromsgrove in Worcestershire. It is an extremely busy line in normal times, but now only runs twice an hour, and is super-spacious.
Twice an hour? Our bus to Cambridge is once an hour (way before Covid-19) and NOTHING in the evenings or Sundays. BTW, nice photo :-) Nothing special, but you will look back on these odd days! My brother-in-law lives in Lichfield.
@g3xbm Thank you. You're right, there's nothing special about the photo other than the fact that I probably wouldn't have captured this shot if it hadn't been for Covid giving me a reason to go for a good walk every day. As you say, a sign of the times.
