Incidents On December 12, 1975, a westbound GO train collided with a Toronto Transit Commission (TTC) bus that was stalled on a crossing at St. Clair and Midland Avenue. Nine passengers on the bus were killed and 20 others were injured. This was the worst accident in terms of loss of life in the history of the TTC and GO Transit systems. The level crossing was replaced by an overpass a few years later. On November 17, 1997, an empty train collided with another train waiting to depart Union Station with over 800 passengers on board. The empty train's locomotive engineer was at the opposite end of the train, and the conductor at the leading end failed in his attempts to relay the situation to the engineer or apply the emergency brake. The two trains then collided at a speed of , causing a partial derailment and minor injuries to fifty-four passengers and two crew members. The subsequent Transportation Safety Board report made recommendations, including making emergency brakes more accessible and that the locomotive engineer must always control the train from the leading end in the Union Station Rail Corridor. On July 8, 2013, a Richmond Hill–bound GO train encountered flash flooding in the Don Valley when a record-breaking 123 mm rain storm fell over a few hours in Toronto area. As the crew worked to reverse the direction of the train back to Union Station, flood waters continued to rise and submerged the entire track and the train itself began to flood. Approximately 1,400 passengers on board had to be rescued by boat. On January 14, 2015, a GO bus on Highway 407 near Weston Road hit a guard rail and rolled into a ditch. One passenger was ejected and crushed to death, and another two in addition to the bus driver were injured. On March 2, 2015, the GO Transit driver was charged with careless driving causing death.
