English: The end of the line at Mill Hill East
As part of the ambitious New Works programme of the 1930s, there were extensive plans to expand the northern-most extremities of the Northern line. One of the plans was electrification from Mill Hill East to Edgware and also the expansion of the Northern Line north of Edgware to Bushey Heath. But the onset of the Second World War halted all the expansion projects. The LNER lines used to branch west just north of Finchley Central, passing through two stations (Mill Hill East and the now closed Mill Hill The Hale) before joining what is known today as the Edgware branch of the Northern Line, just south of Edgware. Only part of this branch was electrified, a single track running to Mill Hill East. The line from Mill Hill East to Edgware continued to be used by goods trains until the mid 1960s when the line was removed.
