that hadn't been decided and at any rate wouldn't happen until
2013-2016 due to platform length issues. Ms Greening didn't reply to
my email querying this.

That would be quite some accomplishment! Even now, the platform at
Bayswater is only just long enough for a C stock train, and that's
stopping slightly beyond the platform edge!
If she gets another carriage added, the trains will have to run
non-stop from High Street Kensington to Edgware Road!
