The station is situated between Wan Chai and Tin Hau stations on the Island Line. The typical off-peak service is 17 trains per hour in both directions, which is a train every 3-6 minutes. There was a time when there was a special service in operation between Admiralty and Tai Koo on the Island Line due to shortage of train operators. This service was withdrawn after 1 October 1986, about 5 months after the extension to Sheung Wan.
