In the October 2019 Modern Railways it is let slip that as part of the Regional part of East Midlands Railway going all-Turbostar that they will take on Class 171s from Southern, with those being replaced on diesel services by Electrostars equipped with batteries. Two questions: 1. Have GTR actually said anything about this? 2. Which Electrostars? With no new fleet actually yet planned for Southeastern and the 379s (which don't currently have 3rd rail shoes and never have, but presumably could have them fitted) possibly not leaving Greater Anglia after all, is there slack in the Southern fleet?
