The stations down the East Lonon Line extension become the responsibility of TfL later this year (October from memory). They are planning on spending considerable money on enhancing the stations. I think Southern were under an obligation to install the ticket barriers in advance of handover to TfL and had to reinforce the floor to do this. So the makeover of the booking hall is a lucky side effect.

Does anyone know why the shelter on platform 2 is unavailable for use - or at least was a couple of days ago?
