PORTLAND, Ore. (KOIN) — What would happen if an active attacker was on a MAX train? Or if a hazmat incident occurred?

TriMet undertook a full-scale emergency drill Sunday that disrupted both the Blue and Red lines throughout the day.

The “full-scale emergency response exercise” played out at the Washington Park MAX Station, both on the surface and “260 feet below the platforms in the Robertson Tunnel.” At least 225 people from more than 20 agencies — fire, medical and police — and emergency management participated in the drill.

Not only were the Blue and Red lines disrupted, the Washington Park MAX Station was also closed all day Sunday.

This is the first time since 2014 that TriMet has undertaken a full-scale drill in the Robertson Tunnel, described by officials as “twin, three-mile tunnels spanning between Multnomah and Washington counties” that opened in 1998.

At 260 feet below the surface, the Robertson Tunnel is “the deepest transit station in North America and the fifth deepest in the world.”

TriMet provided detour options for transit riders. Details at TriMet.org/Alerts
