The UK Government has announced that the £15 billion Crossrail link is to be extended further west to the commuter town of Reading in Berkshire.
From December 2019 passengers will be able to travel directly into central London and the City without having to change at Paddington, reports the Evening Standard.
Under original plans, trains were to terminate at Maidenhead with a shuttle to Slough and Reading, but ministers decided to continue the service to Twyford and Reading, which will be served by two trains an hour.
The 1,500-capacity trains will take 61 minutes to travel from Reading to Liverpool Street and 57 minutes from Twyford.
The extension has been made possible by the multi-billion pound upgrade to Reading station and the electrification of the Great Western Mainline carried out by Network Rail. No further infrastructure works are needed.
There will be no change to existing services between Reading and Paddington. Crossrail will be integrated into the Transport for London charging zone, meaning passengers will be able to pay by Oyster. Trains through the central underground section will run from December 2018.
