HydroFlex on the main line: No 799001 passes year (p88, July 2019 issue), the Clayfield level crossing en-route from Evesham to University received grant funding Long Marston on 25 September 2020. Philip Sherratt through the Department for Transport’s First of a Kind (FOAK) competition in conjunction with Innovate UK towards the start of main line testing. The trial has seen Class 319 EMU No 319001 rechristened as No 799001. On board the train space within one of the four carriages houses batteries, a hydrogen fuel cell and hydrogen tanks. The two batteries are supplied by Denchi and work in hybrid with the fuel cell from Canadian firm Ballard, which is controlled by software written by the University. The hydrogen tanks are supplied by Luxfer.

AUTOMATION Dr Stuart Hilmansen, Reader in Railway Traction Systems at the University of Birmingham, told Modern Railways work over the last year has concentrated on automating functions within the train to reduce human input, including further development of HYDROFLEX TAKES the university’s control software. An important factor in moving trials from Long Marston onto the main line was technical robustness TO THE MAIN LINE and reliability improvements.

As for rolling stock, the Strategy document says ‘The single most urgent requirement for new rolling stock is on the High Speed network’ to provide extra capacity. The document proposes four new bi-mode sets capable of reaching Rye and Eastbourne via the Marshlink, plus eight new electric sets. The main line fleet benefited from 17x4-car Class 377 sets cascaded from Southern in 2017; this resulted in an upgrade for the Maidstone East line.
