ScotRail has begun trialling Hydrotreated Vegetable Oil (HVO) as an alternative to diesel in one of its Class 156 train units. The trial was initiated on 19 February, and is set to run for 12 weeks at the operator’s Corkerhill Depot, with testing carried out in partnership with Angel Trains and Crown Oil.
If successful, ScotRail plans to further investigate the use of HVO as a means to reduce greenhouse gases along railway lines throughout the country, utilising the alternative as a transitionary measure until such time as carbon-neutral fuel sources become more readily available.
