Thameslink3 is the largest single programme affecting the RUS area, though in reality it comprises a significant number of related projects. The key objective is eventually to increase the frequency and length of the trains which pass between north and south London, and therefore has much wider scope than the KRUS area. It includes very major works at Blackfriars and Farringdon, currently under way as at March 2010, and at London Bridge and its environs, after the 2012 Olympic Games. It will largely separate train services through London Bridge to/from Charing Cross-bound from those to/from Blackfriars. This programme will cause a number of sequential recasts of services affecting the KRUS area.
The programme is divided into three stages:
The last stage will, following the Summer 2012 Olympic and Paralympic Games, encompass the wholesale redevelopment of London Bridge station and enhancement of its approaches at both ends. While the project will, upon completion, enhance capacity through London Bridge, during the works capacity will be restricted. At different stages during the work, a number of services to/from Charing Cross and Cannon Street stations will not be able to call at London Bridge. This will have implications widely throughout the KRUS area.
Train lengthening under the Thameslink programme will affect a limited number of stations.
New services from the KRUS area to north London via the Thameslink route may be possible at the conclusion of the programme, but would replace existing services in the KRUS area.
In general, the works will have the greatest impact on suburban routes rather than the longer-distance routes featuring in the KRUS area.
This is scheduled to commence in 2011 with remodelling of the track layout in the Faversham, Margate and Ramsgate areas. Later the route through the Medway towns will be remodelled.
The anticipated train lengthening will affect mostly the suburban services, but will indirectly affect the main-line services.
The RUS summarises gaps in the following groups:
Interventions to address these gaps are themselves divided into 16 options.
Unless otherwise stated the peak-hour trains comprise those arriving in London between 7 and 10am (high peak between 8 and 9) and leaving between 4 and 7pm (high peak between 5 and 6); the hours on either side of the high peak are known as the shoulder peak.
Gap A concerns the danger of future overcrowding during the peak hours, and possible interventions to alleviate this problem. This issue manifests itself differently on various routes (Tonbridge line, route via Bromley South, and others).
Gap B concerns the relatively poor connections within Kent and to adjacent non-London destinations.
The main recommendations of the KRUS cover the period to the 2020, just after the end of CP5. Further developments are envisaged later, but at this stage only very much in outline.
A continued increase in passenger numbers, especially at peak times and particularly on the Thames Gateway, Medway and Tonbridge routes are anticipated. After the CP4 and CP5 interventions, there will be very limited opportunities to expand capacity on the existing network.
Two possible major developments are identified:
