Elizabeth line
The Elizabeth line is a railway line that runs across Greater London and nearby towns, operating similarly to the RER in Paris and the S-Bahn systems of German-speaking countries. It runs services on dedicated infrastructure in central London from the Great Western Main Line west of Paddington station to Abbey Wood and via Whitechapel to the Great Eastern Main Line near Stratford; along the Great Western Main Line to Reading and Heathrow Airport in the west; and along the Great Eastern Main Line to Shenfield in the east.
