TfL Rail

TfL Rail is a commuter railway route in London and the home county of Essex that currently serves the 14 stations on the Great Eastern Main Line between Liverpool Street, in the City of London, and Shenfield.

It is operated by MTR Corporation under contract to Transport for London (TfL), and forms part of the future Crossrail route from Shenfield to Reading and Heathrow Airport.

 TfL Rail took control of the Liverpool Street to Shenfield "metro" service in May 2015. In May 2018, Heathrow Connect services (between Paddington and the airport) and the Heathrow Express shuttle (from Heathrow Central to Terminal 4) will also come under TfL Rail operation. The route will then be re-branded as the Elizabeth line in December 2018, when its central underground section opens.

Between May 2016 and May 2017, TfL Rail carried over 47 million passengers.
