Emergency crews were called to the Stadium-Chinatown SkyTrain Station on Feb. 22, 2021.

A medical emergency led to a service disruption on transit for several hours Monday.

TransLink issued a notice on Twitter at about 6:15 a.m. saying SkyTrain wasn't running between Waterfront Station in downtown Vancouver and Main Street-Science World Station.

A bus service was put in place between the two stations at about 7 a.m. Trains were also operating from Main Street to King George stations. Customers heading to or from Production Way Station had to transfer at Columbia Station.

The issue wasn't resolved until about 1:30 p.m.

Few details were given about the medical emergency, but an ambulance and multiple fire trucks could be seen near Beatty and Dunsmuir streets, just outside the Stadium-Chinatown Station.

CTV News Vancouver reached out to the Vancouver Police Department and Metro Vancouver Transit Police for further details but was told they wouldn't be commenting on the situation.

Canada Line and Millennium Lines weren't impacted, TransLink said.
