The same pair of locomotives collided with vehicles in Baton Rouge and Denham Springs Friday morning in accidents that caused traffic snarls in both cities, authorities said.

Neither accident resulted in serious injuries, officers reported.

The first accident occurred at the Canadian National Railway grade crossing at Airline Highway around 9 a.m. when the lead locomotive, operating in tandem with a second locomotive, hit a tow truck, Baton Rouge City Police reported.

The 123-car freight train blocked the Airline, Wooddale and Lobdell intersections of the railroad, which parallels Choctaw Drive, for more than an hour after the accident, said Sgt. Don Stone.

The incident occurred when the front locomotive stuck a tow truck under tow by a second tow truck , he said.

The driver, Clint Hampson, had tried to beat the train, Stone said.

Hampson, 39, of Central, was cited for disobeying a railroad crossing signal, Stone said.

The train was stopped until 10:19 a.m. when it resumed its route eastward, police said.

About 30 minutes later, a car ran into the side of one of the pair of locomotives as they crossed Summers Street in Denham Springs, said Denham Springs Police Chief Scott Jones.

Again there were no serious injuries, though the stopped train blocked traffic at all of the city’s railroad grade crossings except the one at Hatchell Lane, Jones said.

The two locomotives and freight cars interrupted traffic for about an hour after that accident, police said.

Dwayne Grace, 18, of 7565 Whitley Road in Denham Springs, didn’t stop a 1992 Cadillac for a stop sign at the Summers Street grade crossing, which has no lights or crossing arms, police spokesman Zach Albritton said.

Police cited Grace for careless operation of a motor vehicle and having no driver’s license, Albritton said
