It was the second skytrain problem in 24 hours.
Translink says the Expo and Millennium Lines experienced system wide delays for less than ten minutes late Monday afternoon due to a switch issue.
Sunday night, a switch problem also left the Expo Line unable to run between Commercial-Broadway Station and Waterfront Station.
Buses were called in at around 7:30 p.m. to help stranded Skytrain passengers.
Normal service resumed after several hours.
