Platform 2 at Twickenham, a London-facing bay, has had the track relaid, and crossovers now permit direct running into it from the down line, albeit with a few hundred yards of wrong-line running on the up fast and up slow, but I don't think it's been used much, if at all. The recent rebuilding of the station buildings has allowed space at the country end for the bay to become a through line, but, seeing how little the bay is used, I doubt if it will become a through line for the foreseeable future.
