There is no step-free access to the Jubilee Line at London Bridge from

6 months. Given that the lift shaft is already in place, could the job
not be done much more quickly?

The design of the replacement lift is very different from the one it
replaces AIUI. I believe the new lifts are machine room less lifts.
There was a recent TfL funding paper about this.

here is an excerpt from the paper about scope. There was no more
detail than this.

* Replacement of nine hydraulic lifts with KONE 'machine-roomless'
traction units with gearless drive in line with the Lifts and
Escalators Strategy.
* Project management of Capex interventions for the 20 year
contract life until 2034.
* Enabling works including modifications to lift shafts and
improvements to 'ancillary' services.

So it is planned work then. That leaves me puzzled about why on the Tube map London Bridge has not lost its Jubilee line wheelchair symbol during these works, whereas other stations such as Kilburn lost their wheelchair symbol during the period they didn't have step free access. Anyone know why London Bridge is being treated differently?
