A Chinese goods wagon derailed north of the station at around 2:00 p.m. on 4 June 1988. Nobody was injured, but the derailment led to thousands being stranded at University, Tai Po Market, and Fo Tan stations, leading to an "almost hysterical scramble for road transport". At 5:00 p.m. a lorry overturned in the northbound carriageway of the Lion Rock Tunnel. Together, the accidents caused a "great stoppage" in Kowloon and the eastern New Territories, leading to anger and fights at massive queues for taxi ranks and bus stations. The Police Tactical Unit was dispatched to University station.
