The Expo Line is shut down between Waterfront and Stadium Station, but but service has since been restored.
Fire officials on Friday had linked the source of the fire to a dumpster, but by Saturday it had been determined the fire started within a homeless encampment in an underground area near the exit to the Waterfront SkyTrain station.
The cause of the blaze is under investigation.
