Chiltern Railways - Chiltern Railways Project Evergreen - H

 

 

Evergreen is the name given by Chiltern to the major infrastructure works that the company has committed to over the 20-year duration of its franchise to improve routes and services. This has been divided into three distinct phases.

 

 

The main focus of phase 1 was the redoubling of the Chiltern Main Line between Princes Risborough and Bicester North, with work taking place during 1998, as well as between Bicester North and Aynho Junction during 2001. Furthermore, several stations were subject to reconstruction works. Haddenham and Thame Parkway was rebuilt to have two operational platforms instead of a single platform; a new platform was also installed at Princes Risborough. Finally, the line speed limit was raised following appropriate infrastructure improvements.

 

 

Phase 2 commenced shortly following the award of Chiltern's 20-year franchise period in August 2000. The most extensive works undertaken was the realignment of the route through Beaconsfield, which permitted line speeds to be increased to 75 mph (121 km/h). Further improvements in this phase included the enactment of signalling improvements between High Wycombe and Bicester, as well as between Princes Risborough and Aylesbury, two new platforms were constructed at London Marylebone on land formerly occupied by the carriage sidings, while a new depot was constructed at Wembley.

 

 

The Department for Transport, Chiltern Railways and Network Rail agreed in January 2010 to a £250 million upgrade of the Chiltern Main Line.
