Northern have chosen T&RS Engineering to deliver Maintenance Optimisation on their Class 319 EMU fleet. The maintenance of the fleet, based at the Allerton Depot, Liverpool will be optimised following our proven process to deliver improved fleet availability and reliability. The project will be delivered in two stages, initially on the ‘core’ Class 319 fleet and later in 2017 on the Class 319 ‘FLEX’ units as they are introduced.
