District Line commuters in south west London are facing delays all of today because of strike action by some Tube drivers.

Aslef Union members will walk out for 24 hours (April 13) in a dispute over a driver’s treatment involved in safety incidents who has been ‘reassigned’ to a station staff job.

Transport for London (TfL), as a result, says there would be ‘minor delays’ to journeys all of today across the District Line.

Nigel Holness, London Underground’s (LU) director of network operations, said: “The safety of our customers and our staff is our top priority.

"In this case, a driver was offered an alternative role on our stations following a number of safety incidents in their first few months of driving.

"With so many incidents in a short space of time, despite several weeks of training and assistance, it was simply not safe for this employee to continue in a role as a driver.”

London Buses, London Overground, and South Western trains are currently accepting valid tickets on any reasonable routes.

Aslef’s Finn Brennan claims LU is ‘refusing’ to speak with the union following the row.

He said: “Instead of recognising the concerns of our members, and reps, LU management are refusing to acknowledge that they have failed to follow their own procedures, threatened a disciplinary hearing to make a driver 'agree' to be redeployed, and now refuse to talk to this union.”

But Mr Holness claims the situation ‘is not as the union has described’ because no disciplinary action has been taken against the employee.

He added: “Our action is in line with the safety policies agreed with our trade unions.”
