The Epping Ongar Railway is a heritage railway run by a team of volunteers in south-west Essex, England. It was the final section of the Great Eastern Railway branch line, later the London Underground's Central line from Loughton via Epping to Ongar, with intermediate stations at North Weald and Blake Hall. The line was closed by London Underground in 1994 but reopened between 2004 and 2007 as a preserved railway offering a volunteer-run Class 117 DMU service between Ongar and Coopersale.
