What is intended to replace them is unclear. Using the former Thameslink Class 319 electric units ( now in the Manchester area on the newly electrified Manchester Liverpool routes) would face problems in maintaining current schedules on the Glossop route because of its rising gradient. Despite a recent extensive refurbishment by Northern they are older trains than the 323 units and they do not possess regenerative braking.They are also 4 coach trains and would be too long for some stations on the Glossop route.
We are currently working with the High Peak and Hope Valley Community Rail Partnership to argue the case for the Class 323's being retained in the Manchester area and in particular on the Glossop line. We hope those of you concerned about the possible loss of these trains will also contact the DfT to urge they be retained.
