Following the opening of long-distance station, the three-track station opened in 1972 (now the regional station) has only been used by regional and S-Bahn traffic. Between 1985 and 1999, the regional station had been used by Intercity and later by Intercity-Express services. Until December 2010 some long-distance trains used the regional station at night, when the long-distance station was closed. The long-distance station is now also open at night, so scheduled long-distance trains no longer stop at the regional station. The Cologne-Frankfurt high-speed line opened in August 2002, three years after the line between the Raunheim curve and the Frankfurt Cross tunnel through the new station.
