London Underground says it will launch a new 'Night Tube", which means trains on some lines will run at the weekend for 24 hours:
- Central Line
- Jubilee Line
- Northern Line
- Piccadilly Line
- Victoria Line
The overnight service is due to start in 2015.
Londoners can expect to be caught in the crossfire as union leaders declare war over today's massive cuts to London Underground.
The RMT claims London Underground is about to announce a programme of ticket office closures and the introduction of driverless trains.
