In May 2009, EWS vacated their site.
This part of the site, together with the adjacent Coronation Carriage Sidings was fenced off due to compulsory purchase for the Crossrail project.
All the remaining GWR Factory buildings and the Coronation Carriage Sidings were demolished by mid-2011, with the former northwestern shed turntable donated to the Swanage Railway.

As a result of the development of the new HS2 station on the site, GWR phased-in a closure programme for its 125 Intercity Fleet depot.
In December 2017, maintenance of the Night Riviera was transferred to Penzance Long Rock Depot with the stock laying over at Reading TMD at its northern end.
The last HST to run from Old Oak Common ran from OOC to London Paddington station on 8 December 2018.
A headboard was attached to the front power car, 43093, which said: "81A Old Oak Common LAST HST 8th December 2018".
43093 had already been named "Old Oak Common HST Depot 1978-2018" and was in the Legends of the Great Western Railway livery, but even more was added on this date; a logo which read "Old Oak Common History Makers" and another sign which read "Last HST off Old Oak Common Depot 8th December 2018".

From 2014 onwards, on the former EWS site and northern part of the former Coronation Sidings, a new depot was built as part of the Crossrail project.
Opening on 10 May 2018, it is equipped with stabling and nine maintenance roads.
Operated by Bombardier, it provides full servicing, maintenance and storage for the Class 345 trains which from 2019 will operate between Reading on the GWML and Shenfield on the Great Eastern Main Line.
As a result, the Heathrow Express depot will close when operation of its services is taken over by Great Western Railway in 2019.

Old Oak Common railway station will open in 2026 as a major interchange station between the GWML, Crossrail, Heathrow Express and High Speed 2 line from London Euston to Birmingham, Manchester and Leeds.
