Sunday 20th September 2015 saw the start of the new direct award Great Western franchise, which will run until April 2019 (subject to an option for the Department for Transport to extend for a further year). On the day the franchise started the franchise operator, First Great Western, was re-named Great Western Railway.
Great Western Railway has produced a document setting out an overview of some of the key features. You can see this document here. Propositions for the Avocet Line can be found on page 45, and the document contains a lot of information about new trains, the proposed cascade of existing units to other areas, and a summary of planned timetable changes.
