Windsor Railway Bridge is a wrought iron 'bow and string' bridge in Windsor, Berkshire, crossing the River Thames on the reach between Romney Lock and Boveney Lock. It carries the branch line between Slough and Windsor.

The Slough–Windsor & Eton line is a branch railway line 2 miles 63 chains (4.5 km) long, in Berkshire, England. Trains run between the line's only two stations, Slough and Windsor & Eton Central. At its northern end, the branch line joins the Great Western Main Line, but passenger trains from Windsor rarely use the connection, usually terminating at Slough.
