The rich history of Kensington Olympia station

Wikipedia gives the basics:

The station was originally opened in 1844 by the West London Railway but closed shortly afterwards. It reopened in 1862 and began catering for Great Western services the following year. In 1872 it became part of the Middle Circle train route that bypassed central London. 

The station was bombed during World War II and subsequently closed. It reopened in 1946 but the limited service to Clapham Junction was recommended for withdrawal in the 1960s Beeching Report. The main-line station was revitalised later in the decade as a terminus for national Motorail, and upgraded again in 1986 to serve a wider range of InterCity destinations. 

The station's Underground connection after World War II was limited to a shuttle service to and from Earl's Court.
