Question to the Department for Transport:
To ask Her Majesty's Government what estimate they have made of how many passengers suffered delays and cancellations across the Southern railway network as a result of service failures on 2 July.
The Department for Transport does not make estimates of how many passengers are impacted by delays and cancellations.
Govia Thameslink Railway (which runs Southern services) has reported that, on Monday 2 July, 68% of Southern services arrived at their destination within five minutes of the schedule. A major cause of service disruption was a multiple signal failure between Wivelsfield and Hassocks.
