Representatives of the government announced on October 1 of that year that they were scrapping Citybanan in favor of building a third railway track through the city.

The new tunnel diverts Stockholm's commuter trains from the busy main line through the city.
Citybanan in March 2009. The sign reads, "We're building a tunnel under Söderström [the southern channel around Gamla stan ] as part of the Stockholm City Line."
