[8][9][10] In October 2014, Tower Transit purchased Impact Group[11] which operated 130 small buses for local authorities and schools out of depots in Ealing and Croydon.

[17] Tower Transit's Lea Interchange garage, located in East London, was not part of the joint venture and remained unaffected.

[19][20] The acquisition was finalised on 25 June 2022 and these services are now operated by Stagecoach under the Lea Interchange Bus Company Limited legal entity.

With the completion of Crossrail works, all routes returned to Westbourne Park in June 2017 with Atlas Road retained as a maintenance centre.

[27] Westbourne Park Garage was part of the reconstruction programme undertaken by London Transport in the early 1980s.

Originally, the garage allocation consisted of AEC Routemasters, and a small number of Daimler Fleetlines to B20 "quiet" specification for route 18.

A new 180 metre bus parking area was built on a raised platform over railway lines as part of the Crossrail project opening in 2017.

Westbourne Park garage was transferred to RATP Dev Transit London on 11 December 2021.
