The line was shifted to run along the Yamuna River, and it began operating in 1924. The New Delhi Railway Station opened in 1926, with a single platform at Ajmeri Gate near Paharganj, and was completed in time for the city's inauguration in 1931.[23][24] As construction of the Viceroy's House (the present Rashtrapati Bhavan), Central Secretariat, Parliament House, and All-India War Memorial (India Gate) was winding down, the building of a shopping district and a new plaza, Connaught Place, began in 1929, and was completed by 1933. Named after Prince Arthur, 1st Duke of Connaught (1850–1942), it was designed by Robert Tor Russell, chief architect to the Public Works Department (PWD).[25]
