The eastbound lanes and the inside westbound lane of South Choctaw Drive from North Sherwood Forest Drive to Monterrey Boulevard were reopened Sunday following their closure Friday after a train derailed, Baton Rouge police spokesman Cpl. Don Coppola Jr., said.

The Canadian National Railway train derailed about 9:30 a.m. Friday near South Choctaw and North Sherwood Forest.

Some equipment still remains at the site of the derailment and once it is moved, police will open the outside westbound lane of South Choctaw, Coppola said.

The cause of the derailment is under investigation. The train’s 105 cars carried a range of merchandise and general freight and were heading east from Baton Rouge to Jackson, Mississippi.

The derailed cars were carrying fiberboard, silica pellets and lube oil; one empty tank carried the residue of a toxic chemical called difluoromethane, a spokesman for the Canadian National Railway Co. said, but that chemical did not leak.
