Regular train service on the busy Toronto, Ottawa and Montreal corridor is expected to resume Tuesday morning with just a few delays after a freight train jumped the tracks on Monday.

The derailment took place at approximately 6:15 a.m., about 450 metres from a Via Rail station in Kingston, when 32 of 142 cars went off the tracks.

Via Rail shut down passenger service in both directions as a result of the incident. But by Tuesday morning the company expected to have passengers moving again with just a few delays.

Passengers leaving Kingston and Ottawa for early morning departures needed to take buses.

Up to 10 trips between Toronto and Ottawa and 12 trips between Toronto and Montreal were affected by the derailment. About 3,000 Via Rail passengers were affected by the incident.

Inconvenienced passengers were told that they could reschedule their tickets with no additional fees being charged.

This is the second freight train derailment for CN Rail this month.

On March 1, a CN train jumped the tracks in Pickering. Dozens of the 105 cars in the train overturned, causing commuter headaches for GO Transit and Via Rail passengers. Those trains use some of the same tracks.

A CN Rail spokesperson told the Toronto Star that both derailments are under investigation and would not comment on what may have caused both accidents.

"The Pickering derailment, as well as the one (yesterday), are both under the investigation of transportation safety board," Julie Senécal said.

"So it is too soon to speculate on the cause of those two accidents."

The train that derailed in Pickering was carrying batteries, hydrochloric acid and phosphoric acid. Hazardous materials teams were called to the site but none of the chemicals spilled.

Monday's train was carrying wheat, plywood, molasses, oil and other products. A light industrial oil spilled in the incident but it was quickly cleaned up.
