TfL certainly has a lot of looming issues. But I'd have thought it could
redeploy some of the 315s displaced from the Shenfield line as a very
short-term GOBLIN replacement fleet. Presumably Bombardier would have to
fund this, as it's months late with the new Aventras, and it currently
maintains the 315s anyway.
