The Metropolitan District Railway, also known as the District Railway, was a passenger railway that served London, England, from 1868 to 1933. Established in 1864 to complete an "inner circle" of lines connecting railway termini in London, the first part of the line opened using gas-lit wooden carriages hauled by steam locomotives. The Metropolitan Railway operated all services until the District Railway introduced its own trains in 1871. The railway was soon extended westwards through Earl's Court to Fulham, Richmond, Ealing and Hounslow. After completing the inner circle and reaching Whitechapel in 1884, it was extended to Upminster in Essex in 1902.

Earl's Court tube station is a Grade II listed London Underground station in Earl's Court, London, on the District and Piccadilly lines. It is an important interchange for both lines and is situated in both Travelcard Zone 1 and Zone 2. The station has an eastern entrance on Earl's Court Road and a western entrance on Warwick Road. Another former entrance allowed passengers to enter the station from the other side of Warwick Road, via a ticket hall and subway leading to a concourse beneath the District line platforms. Earl's Court is a step-free tube station; the Earls Court Road entrance provides lift access between street and platform levels.
