Police are looking for the public's help in identifying a man who was struck and killed by a GO train between Mimico and Exhibition Stations Monday morning.

The man was walking across the tracks west of South Kingsway when he was hit by a train travelling eastbound. Police say he was pronounced dead on the scene.

The victim is described as white, in his mid 20s, approximately 5-feet-6, 150 lbs., with short light-brown hair, a light-brown trimmed beard, with no visible marks, tattoos or jewelry.

He was wearing a grey T-shirt, dark Bluenotes blue jeans, black high-top Nike leather shoes with black laces, a black belt, and black socks.

GO train service along the Lakeshore West line was halted for more than two hours following the incident.

The Lakeshore East line also saw delays until 8:30 a.m., with GO Transit saying there could continue to be a few delays on the east and west lines as the investigation continues.

Shuttle buses had been running from Port Credit to Cooksville.

A number of trains between Aldershot and Union had been cancelled or disrupted, as well as one from Hamilton to Union. One Lakeshore East train had been disrupted as well.

GO Transit says there could be lingering delays as rush-hour service resumes.
