Porterbrook to convert Class 350/2 EMU into bi-mode


AN ENGINEERING assessment undertaken by Porterbrook has indicated there is a case for the conversion of a Class 350/2 EMU into a battery/electric bi-mode.

The units are one of the most reliable in service, and Porterbrook says with addition of the latest battery technology, the ‘BatteryFLEX’ – as its been dubbed – would be able to match, or outperform, diesel trains on non-electrified routes.Porterbrook has modelled energy and power demands for routes such as the Windermere branch, where a BatteryFLEX unit would eliminate diesel use on non-electrified lines, while maintaining the ability of these highly reliable trains to operate using overhead electrical wires.

Modelling of Class 350/2 performance over the West Coast Main Line also shows these trains can match or outperform rolling stock, particularly on local services.
