The District Line grew out of the District Railway which was formed to link up the railway termini in London, at first using Metropolitan Railway rolling stock and then later it's own. The District Railway eventually formed a sprawling network spanning London from west to east, becoming the District Line in 1933.
The branch from Edgware Road to Wimbledon (known as the Edgware Road branch of the District Line for obvious reasons) begins on shared tracks with two of the other sub-surface lines. Edgware Road itself was originally part of the Metropolitan Railway and indeed one of the original stations on the first stretch from Paddington to Farringdon.
The branch travels through down through west London including Earl's Court before heading south west via West Brompton and then south of the Thames before terminating at Wimbledon.
