Contentiously, Waterloo-Exeter and Salisbury-Romsey-Southampton locals to GW, with all the 159s and 158s as well as the Salisbury depot transferred. Seems a bit strange to have this diesel microservice pattern on an electric TOC, while if these went to GW, it might allow more through working, eg the Dunbridge and Dean service could run through to say Swindon as a Trans Wilts route, or some Waterloo-Exeters could continue on to say Plymouth, Paignton or Barnstaple.
Might also make it easier to run the Waterloo-Exeter fast from Honiton to Exeter Central if all run in one franchise, with the small stops running as an additional hourly Honiton-Exeter local?
