The connection to the main customs office at Praterstern remained as part of the connecting railway Hütteldorf Hacking north station, starting from 1921 also again with passenger traffic, in continuous operation. It has been part of the S-Bahn trunk line since 1959, the busiest section in the Vienna S-Bahn network, and has been electrified since 1962. Trains of the 4020 and 4024 trains are also used today, as well as the new 4744/4746. However, the station Radetzkyplatz has not been in operation since the interwar period and was demolished after the Second World War.
