Epping is the eastern terminus of the Central Underground Line of London Transport, and is situated outside the M25. It is the second-most northerly station on the underground network(after Chesham). History The line from Loughton to Ongar via Epping was opened in 1865 as an extension of the Eastern Counties Railway line from London Liverpool Street to Loughton. For most of its life it was a normal suburban railway branch, but was included in post-war plans to extend to Central Line beyond Leytonstone. The line from Loughton to Epping was incorporated into London Transport and electrified in 1949. The line beyond to Ongar was thereafter operated as a shuttle — by steam until 1957, and electric until its closure in 1994. Since then Epping has been the true eastern terminus of the line. The station The station preserves its original buildings on the main platform, as well as an attractive Great Eastern Railway footbridge across to platform 2. There is a ticket office, a large 500-space car park, and a bus stop for services to Harlow and Chipping Ongar. The station is in zone 6, and normally enjoys an off-peak 10-minute frequency of trains to West Ruislip — one of the longest journeys possible on the Underground system, nearly 35 miles away on the other side of the capital.
