New night bus services could be introduced with the arrival of the 24-hour tube in September, while other routes could be cut back.

Transport for London (TfL) is consulting on introducing 20 new night buses at weekends, following the same route as the day service, to help passengers travelling to and from London Underground stations.

But some routes could be cut back at weekends, where TfL claims the night tube, running every ten minutes, will reduce the need for extra buses.

Plans for new weekend services include the 34, from High Barnet to Walthamstow Central via Arnos Grove, and the 307, from Barnet Hospital to Brimsdown, via High Barnet, to run every half an hour.

The 114, from Mill Hill to Ruislip Station, and the 183, from Golders Green to Pinner, will also run every half an hour.

Proposals have also been laid out to cut three weekend night bus routes in Barnet.

The N20, from Trafalgar Square to High Barnet, could drop from every ten minutes to every half an hour.

The 134, from Tottenham Court Road to North Finchley, could be reduced from every 12 minutes to every 15 minutes, and the N5, from Trafalgar Square to Edgware via Golders Green, could be reduced from every ten minutes to every 15 minutes.

Andrew Dismore, GLA member for Barnet and Camden, expressed concern about the proposals.

He said: “TfL’s current plans will cut night bus services to Camden and especially Barnet. This will affect those who depend on the service for less expensive reliable and safe transport to and from unsociable shift work.

“Many of these night time workers are amongst the lowest paid in London and to force them to use the underground at the tube’s higher fares is very unfair.

“Reductions in the 134, N5 and N20 will result in these workers taking more expensive tube journeys and walking further at night.

“I am therefore writing to TfL objecting to these short sighted and unfair cuts which favour those on higher incomes who are in the West End to enjoy themselves over those who need to work there as cleaners or hospitality staff, for example.”

Mike Weston, TfL's director of buses, said: “The introduction of the night tube will see journey times for customers cut by an average of 20 minutes, with some reduced by more than an hour. At the same time, night buses will continue to run frequently across London complementing night tube services, giving passengers more choice.

“Our proposals include the introduction of up to 20 brand new suburban night bus services that will expand the transport network in outer London.”

The public consultation will end on July 1 and can be visited here.
