Local passengers are currently receiving a very uneven service, especially at major stations like Guildford, Wokingham, Dorking and Reigate but also the small stations. Having a clockface based on even half hourly/ hourly times mean people will be able to turn up and get a train reliably. This will increase local traffic and be better than 1982, especially between Guildford and Redhill.
Not to mention Crowthorne, Sandhurst, Farnborough North and Ash getting a 1tph direct service to Gatwick (assuming Blackwater and North Camp continue to be 2tph). Blackwater, Farnborough North and North Camp are in the Farnborough/Aldershot Built-Up Area, population 253,000 in 2011, the biggest conurbation by far on the route excepting the Reading/Wokingham Built-Up Area, population 318,000 in 2011.
For anyone not familiar with the area, who may be thinking Farnborough surely is the biggest town yet only gets 1tph, the answer is Farnborough North is on the far eastern fringe of the town, has very poor road access and a handful of parking spaces, with no prospect of any improvement. Its (relatively high) usage stats reflect the large numbers of students attending two nearby colleges during term time.
Blackwater and North Camp both have excellent road access and plentiful parking, The former is the railhead for Blackwater, a large chunk of Camberley, Yateley, College Town and the actual north part of Farnborough. The latter is the railhead for North Camp, south Farnborough and Ash Vale.
