The investigation is underway into the cause of the second train derailment in three weeks in northwestern New Brunswick. (Google Maps) ​CN spokesman Jim Feeny says the investigation is underway into a freight train derailment in northwesterrn New Brunswick on Sunday night.

Feeny says one of the cars was carrying liquefied petroleum gas, three were carrying automobiles and one was transporting clay when five freight cars left the tracks in Sainte-Basile, part of the city of Edmundston, at about 10:30 p.m. local time​.

"There are no leaks reported, there is no fire, there is no evacuation and there were no injuries," Feeny said.

Two derailments of this sort in such a close area and such a short period of time is very unusual. - Jim Feeny, CN spokesman

The derailment came within three weeks and 100 kilometres of the derailment in Wapske, N.B., when cars carrying crude oil caught fire.

"We've begun the investigation into the second one but it's too early to draw conclusions at this point," Feeny said Monday morning.

Jim Feeny, director of public affairs with CN, says crews are working closely with the Edmundston Fire Department to clean up the five cars that derailed in Saint-Basile on Sunday night. (Twitter) "This is certainly not the way that we wanted to begin the year in New Brunswick, or anywhere else. Two derailments of this sort in such a close area and such a short period of time is very unusual."

Feeny says two of the cars are still upright and will just need to be placed back on the tracks to continue to Moncton.

"The others that are on their side — one clay, one automobile — we'll deal with those to get them out of the way so that we can get at the LPG car."

Feeny says crews are still working out how they will clear the car that is carrying flammable liquefied petroleum gas from the scene.

He expects that work will begin Monday morning.

"Our people are on site, with the local fire department, and our people are working with the automobiles and the clay car, and will be getting to the LPG car through the morning to deal with it — again working with local authorities."

The train was heading east towards Moncton and the five cars that derailed were at the tail end of the train.

Feeny says the site of the derailment is on CN's main line between Montreal and Halifax, and describes it as "very accessible" to crews cleaning up the cars.

He says that rail line currently sees four freight trains per day, with two heading east and two heading west.
