Report and further consultation on Bakerloo Line extension

Will the current Bakerloo line building just become a ventilation shaft then?

Perhaps a slightly awkward (long walk) secondary entrance

The existing section of line will remain accessible to trains at least as long as London Road Depot is in operation as the junction will be north of there, and there will likely be no point spending money changing the access to the depot.

Sorry, my mistake.

Not sure about anyone else, but talk of extensions on London underground lines always gets the inner kid in me very excited!

Its great to see the project moving forward a little, but I still worry whether the funding will be available.

They are planning for the extra trains to be stabled at Wearside Road, about halfway between Lewisham and Ladywell stations. consultations.tfl.gov.uk/tube/bakerloo-extension/user_uploads/wearside-road-council-depot-factsheet-9.pdf

More trains will obviously be needed, but it doesn't say how many - I suspect it's not possible to put an exact figure on it before detailed designs are done. The implication is that the extension and new trains will come online around the same time - after the Piccadilly line has got its new trains.

Check out the carto.metro web site to show track diagram.

Travel time between Lewisham and Elephant on the extension would be 15 minutes according to docs. For a 27tph service this implies about 14 extra trains.

However upgrading the Bakerloo core to 27tph will need considerably more trains too.

Travel time from Hayes to Lewisham is 23 minutes on current NR services. If we imagine that's reduced to 20 minutes that'd need about 18 more trains, although the plan is to turn some at Catford Bridge so it may be more like 15.

This is just guesswork though!

Chris M comment earlier...

But that might require more space at Wearside Road, and wouldn't be realisable until after it is open.

This sounds interesting, is there any more information available publicly about this?

Thanks for that. I had only seen a couple of lines in a TfL document which listed it as a potential development site.

Eight trains shared between two overrun tunnels, with one train in a platform at Lewisham never sounded ideal, even with an access shaft at the far end in Wearside Road Council depot site. Further extension to Hayes would have required a new home for them. Current proposal is to surface and stable on the Wearside Road Council depot site, but if you look at the site it is triangle shaped with the neck at the south end suiting stabling from Ladywell.

The 2017 consultation ignored Hayes, concentrating on the tunnel section to Lewisham. It seemed to me that onward to Hayes was always the plan, but tunnel would take longer for permission and build so both would complete around the same time. The latest consultation suggests the same to me, especially with stabling based on such a shaped site. There will still be need for more stabling, probably on an abandoned goods yard along the line.

The official government flood maps (which you can access at
flood-warning-information.service.gov.uk/long-term-flood-risk/map) do not show there to be any flood risk for the actual council depot site, which is immediately to the north of the river. The only “Medium risk” area is immediately to the south.
