The Land of Confusion

The opportunity was taken to rename Shepherd's Bush (Met) station to reflect its close proximity to the market, as part of the massive redevelopment of the area. It does also mark the station as being completely separate.

Hammersmith's two stations are treated as an interchange, and thus share the same name albeit being 2 different stations. If memory serves there is both a subway and fairly decent pedestrian crossings providing step-free access between the two.

Edgware Road's two stations are not treated as an interchange, but are quite close and can be accessed safely either by subway(s) or via pedestrian crossings. They share the same name as they are both on the Edgware Road within a short distance of each other. There is not really another name either of them could have without confusing people.

Neither of the stations you mention require the user to jaywalk across any road to reach them safely.

There was, but it's now closed.

Now that Wood Lane is open there's no emphasis on Bush as an interchange, another reason to change the name of the Met station.

Joe S the shopping centre is built around Hammersmith station, with an entrance at either end. To get to Hammersmith Met you have to come outside the shopping centre and cross the road, they are totally different stations.

It's only the Marylebone Flyover that makes the interchange between the Edgware Road stations seem difficult. We really need a London 'Big Dig' to get rid of that section of motorway.

Wood Lane and White City are marked as an interchange, and it's free to change there on Oyster PAYG. Building a bridge between the platforms would have been pretty expensive and only slightly more convenient, which isn't worth it given the likely level of interchange traffic.

Despite its reputation, I've always found changing between the Hammersmiths pretty quick and easy.

It also seems odd to rename one station to avoid having two "Shepherd's Bushes" in the same area, then promptly open another station with exactly the same name, thus immediately replicating the self same situation! (Yes I know one is LU and the other LO.)

Indeed the name for the area is Shepherd's Bush Interchange, you have bus stops in the stone's throw between the two stations. It's a very good spot, I reckon you're pretty much one change away from most of the UK via Tube, Overground or Bus.

And it stank too!

I've only changed between the Edgware Road stations once, from Bakerloo to Met, but part of that interchange was in a subway.

Ok, fair enough, you win. I'll just have to look out for that two line highway next time I cross a station concourse .....

Actually they aren't. The Bakerloo station is on Edgware Road but the SSL station is on the corner of Chapel Street and Cabbell Street, with Marylebone Road to the North.

Chuck a right down the side street immediately outside the SSL station, bear left, cross over the 2 slip roads under the flyover and you are at the Bakerloo station in half the time. No subways. Takes 2 mins.
