In June 2011, Peter Dearman of Network Rail suggested that the third-rail network will need to be converted into overhead power lines in the future. He stated, "Although the top speed is 100mph, the trains cannot go over 80mph well and 25% of power is lost from heat". Agreeing that conversion would be expensive, he also said that the third-rail network is at the limit of its power capability (especially as trains become more advanced in technology). The July 2012 Department for Transport High Level Output Specification for Network Rail Control Period 5 includes the conversion of the power supply on the South West Main Line between Southampton Central and Basingstoke from 750V DC third rail to 25kV AC overhead as part of a scheme to provide improved rail freight capacity from Southampton Port. The specification also requires that this conversion is considered as a pilot scheme in order to develop a business case for full conversion & modernisation of the Southern Region rail network.
