Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment he has made of the resilience of the (a) software on the Siemens Class 700 trains and (b) signals across the Thameslink route after the power supply problems on the rail network on 10 August 2019.

The major power outage on 9 August 2019 caused significant disruption to rail services and customers. The industry is reviewing what happened, to learn lessons from how the incident was managed so that their response can be improved for passengers in any future disruption, irrespective of the cause.

I am happy to update the Honourable Member on the findings of this review once it is complete.
