I am on a train travelling to a booking, the trains are running. At a main line station some delays due to mechanical failures,passenger medical emergency, only one train I heard cancelled due to staff shortage.
I haven't travelled by train for 2 years, so can't comment on how normal this is. I set off allowing plenty of time.
I only found out about the ASLEF action yesterday, I had looked up strike action before accepting the booking and kept an eye on it last week.
