CHILI, N.Y. -- Multiple fire departments were called to the scene of a tractor-trailer fire inside the Kenworth Northeast Group building Saturday morning in the Town of Chili.

Crews arrived to find heavy smoke inside the Airline Drive facility and the cab of the truck on fire around 4 a.m.

They say the sprinkler system had activated and held the fire in check until crews could get to the scene.

They called for backup from several nearby departments due to the size of the building.

Crews from Gates, Rochester, Chili and Ridge Road all worked to get the fire under control.

They tell us the building has some water and smoke damage but no fire damage.

No word on what sparked the fire.
