Discontinuous third-rail idea for West of England line

‘Islands’ of third-rail electric power are being assessed for the West of England line between Basingstoke and Exeter.

Network Rail and South Western Railway have been working for two years on plans to remove diesel trains on the long-distance route.

They have involved train manufacturers and rolling stock leasing companies in studies to fit battery power to either Class 450 Desiros or new Class 701 Arterio trains, able to recharge on sections of discontinuous third-rail track.
