42-year-old Joseph C. Mounts of Felton was trapped in the wreckage, and it took more than 20 minutes before he was pulled out.
Police say Mounts had made a delivery and had gotten back into the truck when a CSX train approached.
He was taken to the hospital where he is listed in critically injured.
