Shepherd's Bush station on the Central Line is closed until mid October for modernisation. What are they actually doing?
This factsheet goes over the details. Basically the plan during the closure is:
- Demolish the existing building
- Remove the escalators and install new ones while the building isn't in the way
- Build a much larger new building, with a large entrance facing east the bus and Overground station, rather than the narrow entrance facing the street.
- Get started on refurbishing the platform area
Missing from the current plans is the installation of lifts and any other below ground works.
This page describes a possible scheme where two new shafts will be dug down to the existing horizontal ventilation tunnel, which will be enlarged for passenger use. The west shaft will connect to the station building and contain a lift, while the east shaft will contain a new set of emergency stairs. A second lift will connect this shaft to the platforms, coming out between them, part way along. You can sort of it see how this works
in this picture [hosted by Always Touch Out], though not really.
This news article says London Underground "admitted they now had no plans" to install lifts, and the blurb
on TfL's site goes no further than saying they're "evaluating a congestion relief and step-free access scheme". On the other hand,
this article says the new shafts have already been created. So I've no idea what's going on.
One thing to note is that, as far as I can tell, there are no plans to enlarge or significantly alter the existing escalator, stair and platform arrangements during any of these works, beyond basic refurbishment.
(btw I don't buy the conspiracy theories on this. If TfL's claims about needing to close the station to replace the escalators are even slightly true, then making it coincide with the station building being out of the way and getting it done before the shopping centre opens is such a forehead-slappingly sensible plan I'm shocked they ever proposed anything else)
