A severed cable suddenly halted a northbound light-rail train between the University of Washington and U District stations Friday night, stranding cars packed with passengers coming from the Apple Cup game who were stuck in a tunnel, Sound Transit said Saturday.

The train came to a halt in the tunnel around 8:25 p.m. after an electric cable connecting the first car with three trailing cars severed, according to the transit agency. After more than half an hour, some frustrated and confused passengers made the risky decision to use the emergency exits to leave the train and walk through the tunnel.

Sound Transit suspended service north of the University of Washington station, hampering rides home for Friday’s Apple Cup crowd leaving Husky Stadium.
