The "City and Suburban Electric Railways (Amendment) Act", Act No. 13 of 1947, made provision for the construction of further electric railways in the City of Sydney, serving the eastern, southern and south eastern suburbs. This Act amended the earlier scheme proposed by Bradfield in 1916, which had provided for the previous construction work. The City and Suburban Electric Railways (Amendment) Act of 1947 made provision for the construction of of new suburban electric railways. New construction was carried out including the construction of four underground platforms beside Central Station at Chalmers Street (only two would be used for the Eastern Suburbs line, the other two would be used for the Southern Suburbs line). These works were a diversion from Bradfield's plan which had trains emanating from St James not Central. Further, instead of running parallel to Oxford Street, the line would run via Kings Cross to Bondi Junction. The second stage of works would extend the line through North Bondi (Muriverie Road Station) and Rose Bay (Dover Road Station).
