The preferred route for High Speed 2 would see the high-speed line running parallel to the East West Rail between and Claydon. It is proposed to construct an infrastructure maintenance depot between Calvert and Steeple Claydon within the chord linking the former Great Central Main Line and the reinstated Oxford to Bletchley line. The depot would provide the facilities for railborne maintenance equipment needed to service the line. The preferred site, called 'Thame Road', and a fall-back site, 'Great Pond' were announced in December 2010. The nearby Calvert Waste Plant has also been identified for heat and power generation.
