Rail passengers are facing a fourth consecutive day of travel disruption on Friday as RMT union members launch a fresh 48-hour walkout.
The strike at Network Rail and 14 train operators means only around 20% of normal services will run with trains starting later and finishing earlier.
The walkout is again hitting key TfL services in London with severe delays to Elizabeth Line trains running between Paddington and Reading and Liverpool Street and Shenfield.
The London Overground, Circle, Hammersmith & City, and District lines are also severely affected while the Bakerloo line and Overground are part suspended.
Meanwhile Rail Delivery Group (RDG) has offered train drivers a 4 per cent pay rise over two years, after Aslef union members striked on Thursday.
If accepted, the proposal would mean the base salary for the average driver would increase from £60,000, to almost £65,000 by the end of 2023, RDG said.
Aslef told the Standard it has not seen the offer, sent on Friday evening, and will not be responding until next week.
Prime Minister Rishi Sunak revealed he has invited union leaders for talks on Monday.
“We want to have a grown up, honest conversation with all union leaders about what is responsible, what is reasonable and what is affordable for our country when it comes to pay,” he said during a visit to a London school on Friday morning.
