This from Network Rail...
Network Rail will be keeping the rail lines serving London's airports open around the clock tonight to help get stranded air passengers home.
Weekend engineering work on the Anglo-Scottish routes - the east and west coast main lines - has also been cancelled to enable more direct services to run.
Paddington, Liverpool Street, Victoria and Gatwick - some of Network Rail's, and the UK's, biggest and busiest stations - will also stay open around the clock tonight.
Network Rail is also talking to retailers at these stations about extending their opening hours to assist late arriving passengers.
Good effort!
