[1][2][contradictory] The EC&TJR was incorporated by the Eastern Counties and Thames Junction Railway Act 1844 (7 & 8 Vict.
It opened on 29 April 1846[3] from Stratford to Bow Creek[4] to transport coal from a pier on the mouth of the River Lea.
In 1985 third-rail electrification was extended from Dalston via Stratford to North Woolwich, and electric trains started to run through from Richmond.
Part of the reason for this was that only one track beyond Custom House through the Connaught Tunnel was electrified, which restricted the service that could be provided on the easternmost section.
The Jubilee Line Extension of the London Underground was built along the alignment of the former western tracks from Canning Town to Stratford, and opened in 1999.
The Custom House to North Woolwich section of the railway, including the Connaught tunnel, has been reused as part of the Elizabeth line.
