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. In particular, work has focused CLASS 799 MAKES DEBUT RUN ON COTSWOLD LINE on the amount of power provided HYDROFLEX, THE UK’s first Secretary Grant Shapps travelled and the University of Birmingham, by the fuel cell and batteries full size hydrogen train, made on the train and announced that which have together invested to avoid the possibility of an its debut on the main line on the Tees Valley would host the more than £1 million in the project. over current event.
