The Sydney Suburban & City Underground Railway - Sydney - New South Wales 

Sydney’s suburban railways multiplied in the later nineteenth century, but steam trains still dumped you at the city fringe and left you to the trams. John Job Crew Bradfield spent years arguing for the other idea: electrify the metropolitan lines, take them under the park, loop the city, and throw a harbour crossing. War delayed the dig. Then cut-and-cover through Hyde Park produced Australia’s first underground passenger stations.

The first City Railway section — new electric platforms at Central, plus Museum and St James — opened to passengers on 20 December 1926. (A trial train with Bradfield aboard had run on 9 December; the public date is the 20th.) Town Hall and Wynyard followed on the western arm as the Harbour Bridge approaches advanced; those stations and the bridge railway opened with the Bridge in 1932. St James sat as a stub terminus for three decades until Circular Quay station closed the City Circle on 22 January 1956. This is not the Eastern Suburbs Railway (Bondi Junction, 1979) and it is not the Metro.
