The Warren County School System has extended its transportation contract with Durham School Services for another year, the extension getting more buses and equipment for the county.“We were offered five more buses by Durham for extending the contract,” said Director of Schools Bobby Cox in suggesting the Board of Education vote to extend the contract with Durham for one more year.The original contract with Durham was for three years with the possibility of a one-year extension, which was just exercised.“They will also help us replace about 30 cameras on the buses,” Cox noted, pointing to security cameras on the fleet of Durham buses.Cox said the county’s work with Durham has been beneficial.“There’s been cost savings and they’ve improved safety,” Cox said, noting the county could save nearly $100,000 in fuel, that amount partially due to cheaper costs.While happy with Durham, Cox said at the end of the contract, the school system should consider listening to pitches from other companies.“When we get to the end, we need to step back and see where we’re at,” Cox said.
