Plans to axe the ticket offices and redeploy staff to ticket halls and platforms were confirmed last year by Mayor Boris Johnson and Mike Brown, Managing Director of London Underground
Both the Mayor and LU say the closures are necessary to modernise the service for Londoners and reflect the ongoing move away from paper tickets to Oyster and contactless fares.
The RMT union opposes the cuts on safety grounds and warn disabled passengers may find themselves unable to complete their journeys due to a lack of staff, claims denied by LU.
Last week the union announced Tube staff would hold a 48 hour strike from 9pm on Monday April 28th followed by a three-day strike 9pm on Monday May 5th.
The strike is expected to cause widespread disruption to passengers.
Earlier on Thursday LU bossed urged the RMT to engage in talks to resolve the differences between the two sides.
Passengers are being advised to check TfL’s website for details of services and to plan alternative routes if the strike goes ahead.
