 In 2020, Network Rail announced that they are planning to upgrade Reigate station, which includes constructing a new 12-carriage bay platform (number 3) on the south side of the station, and extending the existing platform 2 to also accommodate 12-car trains.Currently the track layout just east of the station forces Southern to turn its trains around on platform 2, and since this platform is not long enough to accommodate 8-car sets, Southern services to and from Reigate are limited to 4 carriages in length.The upgrade would enable longer trains to serve the station, and the new bay platform would allow trains to/from London to terminate there instead of occupying the through westbound track, thus improving reliability on the whole line.
