Prior to 2004, all long-distance trains serving Seoul terminated at the nearby Seoul Station, but with the opening of the Korea Train Express (KTX), Yongsan Station took over some of Seoul's services.
In 2004, a major cinema opened adjacent to the station. In August 2006, the whole station building was made into a large department store, called IPark Mall.
The building now includes the railway station, subway station, the CGV cinema and several restaurants and shops, as well as housing the first building of the Yongsan Electronics Market. There is a bridge connecting I'Park Mall and the Yongsan Electronics Market.
