Most passenger services on the Great Eastern Main Line are operated by Greater Anglia. Since 2015, the Shenfield "metro" service has been controlled by TfL Rail and the Lea Valley Lines to Enfield Town, Cheshunt (via Seven Sisters) and Chingford are operated by London Overground. A small number of late-evening and weekend services operated by c2c run via Barking. The station is split into two-halves: the "west" side for the Lea Valley Lines services and the "east" side for services via Stratford.
