TESTING of the first 'Turbostar' multiple unit to be converted to run on hybrid power has been taking place at the Ecclesbourne Valley Railway heritage line in Derbyshire.
The battery-diesel set, owned by Porterbrook and tagged 'HybridFLEX; is undertaking a programme of tests between Duffield and Wirksworth, before returning to Chiltern Railways.
The tests will allow engineers to fine-tune the software ahead of live main line trials.
