We are proposing an upgrade to the Brighton Main Line, to provide more reliable, more frequent and faster services for the 300,000 passengers who rely on it each weekday, and to provide the capacity needed for future growth.

The Croydon Area Remodelling Scheme

The Croydon Area Remodelling Scheme (CARS) is the largest and most complex part of our longer-term Brighton Main Line upgrade proposals.

CARS would remove the most operationally challenging bottleneck on Britain’s railway network, located in the ‘Selhurst triangle’, the junctions north of East Croydon, and through East Croydon station.

The bottleneck at Croydon causes delay and knock-on delay across the network every time an incident occurs and it means there is no capacity to run more trains to meet future passenger growth, leading to overcrowding in the years ahead unless action is taken.

We propose to unblock the bottleneck to provide more frequent, more reliable services across the Brighton Main Line and its branches.

To fully deliver our proposals we would need to obtain powers, through a Transport and Works Act Order (TWAO), to work outside the railway boundary.

We are currently in the process of preparing an application for these powers, referred to as the East Croydon to Selhurst Junction Triangle Capacity Enhancement Scheme (“the Scheme”).

First public consultation

From 5 November to 17 December 2018, we held our first consultation on the Scheme.

For our first round of public consultation we held 11 public events in the Croydon area, over 20 passenger engagement events across the route and people could also view and comment on the proposals on-line.

A total of 840 people responded to our consultation. Of the 840 responses, 70% came from Croydon and South London residents, while the remaining 30% came from across the route and some from further afield.

Consultees were asked whether they agreed or disagreed with the concept of unblocking the railway bottleneck at Croydon. Over 90% of people who responded either agreed or strongly agreed with the proposals. 7% were undecided and 2% disagreed or strongly disagreed with the proposals.

Some of the most common comments were;

  • to progress as quickly as possible
  • more information please
  • concerns over disruption during construction, both to the train services and the
  • road network; and
  • strong support for Norwood Junction station redevelopment.

Next steps

We are continuing to work through detailed feedback from the first public consultation which has already resulted in some changes to our designs. These designs are still developing, and we will now formally consult on our proposals to unblock Croydon bottleneck in 2020.

Our proposals are unfunded, as are other elements of our Brighton Main Line strategy. While we develop our plans, we will also be making the case for investment in this vital growth corridor.

To unblock the Croydon bottleneck and provide more reliable, more frequent and faster services we are developing proposals to provide:

An expanded and enhanced East Croydon station

A rebuilt station with two additional platforms, a larger concourse with improved facilities for passengers and better connections with the town centre and other transport links, supporting the ongoing regeneration of central Croydon. These new station works would also be designed to allow for new offices and homes to be built next to the new station in the future.

‘Selhurst triangle’ remodelling

We would improve track layouts north of East Croydon station and remodel the junctions at the ‘Selhurst triangle’, by removing the existing junctions and building new flyovers and dive-unders.

Lower Addiscombe Road/Windmill Bridge reconstruction

To remodel ‘Selhurst triangle’ junctions and provide more platforms at East Croydon station we would need to expand the railway north of East Croydon station. This would require the current bridge over the railway to be rebuilt to provide space for additional tracks.


More reliable journeys

By improving track layouts, remodelling the ‘Selhurst triangle’ and constructing new tracks and two new platforms at East Croydon station, we would remove the bottleneck which causes delays and disruption, improving the punctuality of services.

Faster journeys

More tracks and remodelled junctions would also mean we would be able to speed up some services through the area.

More services

Once we deliver our proposals to unblock the Croydon bottleneck to improve the reliability of existing services, we would then be able work with train operators to consider running more trains.

A boost to the regional and national economy

As the main route connecting the capital with Gatwick Airport and the south coast improving the Brighton Main Line will provide a significant boost to the regional and national economy.

An expanded and enhanced East­ Croydon station

We would increase concourse space, provide new entrances and transform passenger facilities.  The work would allow areas next to the station to be developed in the future.
