The London and South East RUS stated that it was anticipated to build
an NLL and WLL station close to the HS2 station at Old Oak Common. I
was wondering how likely it was that the NLL station would be built at
North Acton (where the NLL crosses the GWML, as suggested in the Park
Royal Planning Framework, (http://www.london.gov.uk/sites/default/
files/park-royal-oapf-chaps1-9.pdf) p39). Footbridges could then run
alongside the railway lines to link to the Central Line and HS2
stations.

Also, the WLL station could be built immediately south of Mitre
Bridge, with access to HS2 via North Pole Depot.

Also, the Earl's Court and West Kensington Draft Joint Supplementary
Planning Document (http://www.london.gov.uk/sites/default/files/
11_03_03_ECWKOA-Draft-SPD.pdf, p178), suggests extending the platforms
at West Brompton northwards to allow 8 car Southern services to run.
This would also allow a new access to the station, to reduce pressure
on the existing entrance. Is it possible that this entrance would
allow a proximity interchange with Earls Court station?
