We are delighted to announce that Northern have chosen T&RS Engineering to undertake maintenance optimisation of their Class 156 fleets based at both Allerton and Heaton depots. Our proven process will ensure that Northern will introduce a new exam regime that meets with their operational requirements and delivers improved availability. Our process will also provide a maintenance regime that focuses on improved fleet reliability and reduced visits to their depots for exam work. This announcement follows our successful implementation of maintenance optimisation on their Class 319 fleet earlier this year.
