This was on a new alignment which forced the construction of a new westbound (down) platform further back from the old line.
This doubling required the construction of a new platform for westbound (down) trains.
This necessitated the construction of a southbound platform between the line and the canal, resulting even today in a narrow concourse.
Work began in May 2008 on clearing the site for the construction of a new platform.
In 2005, Transport for London began the construction of a third platform at the station.
There were several other requests for improvements, including for the construction of a platform, largely without success.
However, being a convenient place for a loop during the rebuild, construction of a small platform (with no other facilities) was undertaken during 2009.
Possibilities include replacement of the spikes on the ledge or the construction of a platform elsewhere on the building's exterior.
A passing loop was installed here in 1897 which necessitated the construction of a second platform to serve trains towards Westbury.
It also recommended improved access to the camp site itself, construction of a viewing platform and interpretative signage.
