CHICAGO (CBS) — Metra is advising riders on the BNSF lines to avoid Union Station, after a person was fatally struck Wednesday afternoon by a train in west suburban Riverside.

Shortly before 3 p.m., inbound and outbound trains were halted.

BNSF passengers are being asked to use the Union Pacific West line as an alternative route, or make other transportation arrangements to prevent overcrowding.

Tracks reopened shortly before 6 p.m., though Metra says trains are moving at reduced speeds.

BNSF riders should expect extensive delays.
