Its willingness to spend money on roads rather than railways may prompt Transport Scotland to consider discontinuous electrification, allowing BEMUs to provide intercity services. This may prove to be a useful 'stopgap' solution, but carrying heavy battery equipment is hardly a sensible use of scarce resources.
A Hitachi Class 802 unit had one of its diesel generators replaced temporarily with a 700kW battery. It was able to run on battery alone for 70km and achieved 140km/h (87 mph).
It is important that this promising news on progress with intercity battery trials doesn't tempt the cash strapped Rail Directorate to consider discontinuous electrification to be the answer to financial constraints.
