The Rail Yard Apparitions by Samuel Brower

Ben Suarez, a college student with the need for third shift work, takes a job as a night watchman at a nearby rail yard. On his first night, as he makes his rounds, he begins to discover clues that tell him he will have to face more than just sleep deprivation in his new profession. Strange things begin to take place, and using his smart phone and text exchanges with his girlfriend to research, he finds that the grounds he walks upon are home to a terrible and murderous past.
