Electrification and battery technology are never far from discussions about decarbonisation of the railway. There are a number of solutions, including discontinuous electrification and battery-hybrid technology. We visited Salisbury Traincare Depot, home to South Western Railway’s Class 159 fleet. Richard speaks to Neil Drury, Engineering & Infrastructure Director for SWR about how the operator is thinking about the electrification challenge on its network.
