Federal authorities were hunting Friday for more than 100 rifles stolen from a boxcar parked in an Atlanta train yard.

The weapons were taken from a CSX rail yard on the city's northwest side in mid-November, said Richard Coes, a spokesman for the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives.

The weapons include assault rifles that Coes described as "AK-style." He declined to discuss other aspects of the case.

Gary Sease, a spokesman for rail line CSX Corp., said the Jacksonville, Fla.-based company is cooperating with law enforcement to recover the weapons and investigate the theft.

The rifles were stolen on or around Nov. 12, authorities said. The boxcar was parked at the CSX Tilford Yard about four miles northwest of downtown Atlanta.

The Tilford Yard is one of the company's major rail yards in Georgia, according to the company's website.
