Celadon Trucking Services has purchased more than 1,500 new tractors to add to its overall fleet.

The order consisted of three different tractor models, the Kenworth T680 and the LoneStar and ProStar tractors from International.

“One of Celadon’s hallmarks has always been the newness of our company fleet,” said Celadon CEO and President Paul Will. “The key for us with these new ProStar tractors is to help recruit company drivers to our fleet as well as offer a reward to our existing drivers.”

The Kenworth tractors will be used by the company’s expedited team operations. The LoneStar models are for the Lease Purchase division, and ProStar tractors are for the company’s core driving fleet, according to Celadon.

The company said the purchases are part of a substantial investment in expansion that was fueled by recent acquisitions. In past months Celadon has been adding three to four teams each week to its expedited fleet, which currently is made up of 275 teams in the U.S. and Canada.
