this was the first stop out of Paddington for main line trains; it remains the first stop for Hammersmith & City services. The station was hit during the 1940-41 blitz, with track, the platform and a nearby main-line train taking bomb damage. During the quadrupling of the Great Western Main Line (GWML) in 1878, a dive-under, known as Subway Tunnel, was constructed between Royal Oak and Westbourne Park. This was for Hammersmith & City services, allowing them to cross the main line without interfering with the flow of traffic; it was brought into use on 12 May 1878. To accommodate the additional track of the main line, it was necessary to reduce Royal Oak station to two platform faces; the former down platform was removed (its track becoming the up main), and the southern of the two former up platforms became the down platform. Trains along the GWML ceased to call at Royal Oak from 1 October 1934, but the Hammersmith & City service remained. Ownership of the station was not transferred to London Transport until 1 January 1970. The first GWML stop out of Paddington is now . Ranelagh Bridge depot There had been a locomotive depot at Westbourne Park since 1855, which was replaced by the Old Oak Common depot in 1906. To avoid the need for locomotives to make the round trip from Paddington just to be turned, coaled and watered, a small maintenance facility for locomotives was constructed on the southern side of the line, directly opposite Royal Oak station, which occupied part of the site of Westbourne Lodge and its grounds. It was known as Ranelagh Bridge depot, and opened in 1907. There was a turntable, a water tower, a coaling stage and sidings where about 15 locomotives could be held awaiting their next trip west. The turntable was removed in April 1964, and the depot facilities were altered to suit Diesel locomotives; the depot closed in 1980. Coach station proposal At the end of 2018 residents became aware that Royal Oak was under consideration as a possible location for a new coach station to replace Victoria Coach Station, to be built on land north of the station (previously used for soil handling machinery used in construction of the nearby Crossrail tunnels). This was strongly opposed by Westminster's main political parties, given the limited capacity of Royal Oak tube station and other local transport links,
