At 9:14 a.m. on 5 January 2004, 14 passengers suffered minor injuries when a delusional 55-year-old man ignited two gas cylinders full of paint thinner in the first train car of a Central-bound train from Tsim Sha Tsui. The driver decided to complete the journey and passengers were evacuated from the train in Admiralty. Admiralty station was expanded to serve two additional lines: the South Island line on level L6, and the East Rail line extension of the Sha Tin to Central Link project on level L5. The South Island line platforms opened on 28 December 2016, after a public open day on 24 December 2016, giving residents in the Southern District much quicker access to Hong Kong Island's central business district. The opening date was delayed from 2015 due to technical problems in the deep tunnels for the new platforms. The East Rail line extension, expected to open in 2022, will allow commuters from the northeast New Territories to travel directly to Admiralty. A new underground interchange concourse with natural light was built to the east of the current concourse, taking up one level, allowing passengers to transfer to the new lines. The atrium was also expanded. The station expansion, located under Harcourt Garden, incorporated 34 escalators and five lifts to integrate with the existing station. The Sha Tin to Central Link will be one level under the interchange concourse, with the South Island Line being directly below it. Exits E1 and E2 are being rebuilt as one exit to accommodate the glass roof of the interchange concourse. This new exit E will not open until the Sha Tin to Central Link platforms open. While the Sha Tin to Central Link tracks will have sidings for terminating trains south of the station, the South Island Line tracks end at bumper blocks north of the station with no overrun track. The narrowest part of the existing platforms on L3 level was widened to make better use of the first and second car of the Tsuen Wan Line train, as well as last two cars of Island Line trains. Tsuen Wan Line passengers in the Tsuen Wan direction now have easier access to these cars. As for station facilities, the expansion brings along toilets in the paid area, a lift between concourse, ground level and concourse, and artwork in the station. The new station has two artworks. The first is "Sense of Green" by Tony Ip, which is a new, bamboo-covered landscaped deck over Harcourt Garden. The second, "Urban Soundscape" by Otto Li, is located along either side of the escalator shaft between the new and current stations.
