TfL Rail was the concession which operated commuter services on two separate railway lines in London, England and its environs whilst the Crossrail construction project linking these lines was underway. It ran from 2015 until May 2022, upon the opening of the Crossrail central section, when TfL Rail was rebranded as Elizabeth line and the name was discontinued.

TfL Rail was introduced on 31 May 2015 when it took control from Abellio Greater Anglia of the commuter "metro" service between in central London and in Essex. The branch comprised the first 14 stations on the Great Eastern Main Line, with interchange at Shenfield for medium- and long-distance services beyond to East Anglia. TfL Rail had also taken over operation of some services from to Heathrow Airport and Reading. Services were operated by MTR Crossrail under contract to Transport for London (TfL). Between May 2016 and May 2017, TfL Rail carried over 47 million passengers on the Shenfield branch.

MTR Crossrail was created as a new train operating company and took control of the "metro" service between London Liverpool Street and Shenfield from the previous operator, Abellio Greater Anglia, on 31 May 2015. The existing trains were re-painted in TfL Rail livery, and appropriate branding, advertising and message boards were added at the 14 stations along the line. Every station was staffed, from the first train to the last of the day. In June 2017, Class 345 trains began running between London Liverpool Street and Shenfield.

In May 2018, TfL Rail took over operation of the Heathrow Connect service between London Paddington and Heathrow, as well as some GWR services between London Paddington and Hayes & Harlington. In December 2019, TfL Rail took over operation of the Great Western Railway stopping services between London Paddington and Reading. In November 2019, Class 345 trains began running between London Paddington and Reading, as a soft launch of the service.
