the growth in traffic, the overall level of services over the classic routes be broadly retained. By the time of RUS publication, this had been agreed by DfT and Southeastern as regards the Hayes, Sidcup, Bexleyheath, Greenwich and Chislehurst slow lines. The timetable will still need to be revamped to accommodate the HS1 services from Medway and east Kent. Thameslink route The RUS recommends 14tph through Blackfriars towards Farringdon: 4tph, 2 clockwise, 2 anti-clockwise round the Wimbledon loop 2tph non-stop from East Croydon via Herne Hill 4tph from the Catford route 1tph from the Medway area, 1tph from Maidstone, both via Bromley South and (not stopping) via Catford 2tph from Kent House. Because of scarcity of dual-voltage rolling stock, some shoulder peak trains may run at less than 8-car formation. Medium term In the medium term the RUS recommends widespread train and platform lengthening, combined with station improvements to relieve congestion, all concentrated particularly into the near-medium term. The withdrawal of the South London line Victoria-London Bridge local service is recommended, to be replaced by the East London Line Phase 2 Extension (ELLx2) and a Victoria-Bellingham service. Other services patterns will change a number of times in the period according to the availability of infrastructure. Medium term, 2010-12 The main recommendation in this period is for train and consequent platform lengthening, to 10 cars on most Southern Central suburban routes and 12 cars on most Southeastern suburban routes into London Bridge. The lengthening works are required before reconstruction works begin at London Bridge. These in turn have implications for power supply and deporting. This period also corresponds with the delivery to completion of Thameslink Key Output 1, which will facilitate 16tph at maximum 12-car length. This will include an expanded interchange with the London Underground and a new entrance on the south bank of the River Thames. Brighton Main Line (BML) services to Thameslink will all run via Herne Hill (not London Bridge) with peak direction services as follows: 2tph Brighton, 2tph Three Bridges via Redhill, all running non-stop from East Croydon 4tph Wimbledon loop 2tph Kent House 2tph Sevenoaks, 2tph Orpington, all stopping via Catford 1tph from the Medway area, 1tph from Maidstone, both fast via Bromley South East London Line Phase 2 Extension (ELLx2) The SLRUS recommends early implementation of the ELL branch from Surrey Quays to Clapham Junction. It would serve the South London Line (SLL) stations
