Changing London Underground is not a choice - it is essential, and we will not be diverted from moving with the times
Due to the popularity of Oyster just one in 20 journeys made on the network now involves a visit to a ticket office.
Some ticket offices now sell fewer than ten tickets per hour.
In these circumstances it is essential that London Underground (LU) adapts and, as Mike Brown sets out in his message to Londoners, the staffing changes that are being made come with the guarantee of:
The RMT and TSSA leaderships intend to strike nonetheless, even though only around 35 per cent of TSSA members and less than a third of RMT members voted for a walkout.
Mike Brown, LU Managing Director, said: 'I regret that our passengers may face difficult journeys and we are doing everything possible to avert the strike.
'In refusing to talk to us for nearly a week, and demanding that we withdraw all proposals for staffing changes before talks could progress, the leadership of the RMT and TSSA have seemed intent on disruption.
'But changing London Underground is not a choice - it is essential, and we will not be diverted from moving with the times.
'The union leaderships have tried to scaremonger, citing safety issues, but they did not put a single safety-related issue to us during our talks at the conciliation service, ACAS, nor have they responded to our request that they set out their specific safety concerns.
'Londoners will doubtless, like me, be hoping that the RMT and TSSA leaderships finally see sense.
'I urge them to call off this pointless industrial action and meet with us for talks.
'We will not withdraw our proposals, but we will listen to any specific safety concerns.
'I urge the trade unions to work with us to deliver a 21st century Tube fit for our customers and fit for London.'
The Mayor and Transport for London have also today detailed the efforts being made to help people get around the Capital and keep London moving during the strike.
Ninety-three per cent of Oyster customers made their journeys by public transport despite last month's strike.
The union leaderships had predicted the 'paralysis' of London, but in the event LU was able to operate over a third of its normal services, and carry over a million people.
Over a hundred extra buses, capacity for over 10,000 more journeys on the river, and marshalled taxi ranks have been organised.
Planned roadworks are being delayed or curtailed where possible, and TfL will be working to keep road traffic flowing around key transport hubs.
Volunteers will once again be positioned at Tube, bus, and rail stations to assist Londoners with their journeys and provide maps and other useful information.
Londoners who own a bike are encouraged to cycle to work.
Cycle parking facilities are being made easier for newcomers to access, and a Cycling Journey Planner will be available on TfL's website.
The Barclays Cycle Hire scheme - which saw record usage during the last strike - will be available to members, and TfL's contractors will be working to ensure that bikes are redistributed as effectively as possible.
Normal services are also expected to run on London Overground, Docklands Light Railway and Tramlink.
Should the strike go ahead, LU will work to operate as many services as possible, but passengers are advised that significant disruption is possible and that alternative travel options and staggering journey times should be considered where possible.
