Disruptions to train service were expected to continue Friday in the aftermath of a train derailment in Pickering, Ont. where dozens of cars came off the tracks.

Crews sent out to clean up the mess had originally hoped to have the rail line clear by Friday morning. But that target has been pushed back until the afternoon.

The affected rail line is a busy stretch that carries freight, regional commuters and passenger trains.

GO Transit reported that one of the tracks it uses to bring commuters in and out of downtown Toronto remained open after the incident. But delays were experienced on the Lakeshore East line on Friday morning, due to what GO Transit called "operational problems."

Passenger rail service between Toronto, Montreal and Ottawa was also affected by the incident. VIA Rail had to bus passengers around the accident site.

The eastbound Canadian National freight train went off the tracks in an area known as Pickering Junction shortly after 11 a.m. on the railroad's line between Toronto and Montreal. The company said that 32 of the 105 cars in the train came off the rails.

Despite the incident and resulting mess, there were no reports of injuries. Two of the containers on the train were carrying dangerous materials, including acids and batteries, but there were no reports of leaks.

The crash did sever a gas line which ran parrallel to the tracks. Emergency crews quickly evacuated the area while the broken line was capped.

Thursday's derailment came as CN was trying to clear a backlog of freight after the two-week strike by conductors.
