In Katajanokka, shores were filled and built with piers and handsome cargo warehouses. The connections to the harbour improved considerably, when a railway was built there from 1891 to 1894. In 1900, a new customs house was built in Katajanokka. In the same year, the harbour was being excavated and the Eteläranta side was completed. Thus Eteläsatama got its current form. In 1922, Helsinki got the icebreaker Hercules, so that ships could also travel in winter. For transport of heavy cargo, the harbour got a 25-tonne crane in 1894. More cranes were acquired starting from the 1920s, so that in 1939, Eteläsatama already had 14 cranes. In 1936, the city council decided to expand Eteläsatama to the Helsinki shipyard. This included extensive track work to the railways, which were completed in 1952. In the same year, a pier in Katajanokka collapsed into the sea, and part of the long pier had to be closed. The car ferry era between Finland and Sweden began in the early 1960s. Cargo traffic in Katajanokka was discontinued and the railway there was dismantled in the early 1980s. Since that time, Eteläsatama has been used by passenger ships and car ferries.
