After some slight setbacks at the yard due to Colson's inexperience, including taking on more cars than they had in their orders, the two leave Stanton for a zinc plant. It leaves the yard for the main line unmanned. When he tries to reboard the train, it has picked up speed and he falls to the ground trying. While he does, inside the train, the throttle sets itself into highest speed. As it approaches a switch, Dewey sees it is not set to the right track and, against the advice of the other hostler, jumps from the slow-moving train to line it properly. In the locomotive cab at the Fuller yard, Dewey turns the throttle to its highest setting (idle) to enable the train's dynamic brakes. Colson learns that a court hearing that morning did not, as he had hoped it would, end with the lifting of a restraining order preventing him from seeing his wife and son. They take the locomotive out across a bridge to where they will attach their train for the day. He reminds Colson that if there's anything he doesn't know, he should just ask. Barnes and Colson meet by their locomotive for the day, where Barnes, a 28-year employee, finds out that Colson, who will be in charge of the train, is only four months out of training. This, the other hostler reminds him, means the train's air brakes will not be working, but Dewey says they will hook them up after parking the train on another track. In a hurry, one of them, Dewey (Ethan Suplee), decides to forego connecting the air hose between the locomotive and the rest of the half-milelong (1 km) train. Meanwhile, in Fuller, the yardmaster yells at a pair of hostlers who have been standing idle near a train to get it moved so the schoolchildren's excursion train can get out of the yard. While he goes to punch in, the other older workers complain about being displaced by Colson, who they say got his job through family connections in the union. He goes to a group of older workers, with whom he has some barbed words over their age differences, and finds Barnes among them. Arriving at work, Colson, a conductor, gets his orders for the day and learns he will be working with engineer Frank Barnes (Denzel Washington), with whom he has never worked before.

He calls her but she refuses to even answer. Meanwhile, in the southern Pennsylvania town of Stanton, Will Colson (Chris Pine) gets up for work, stopping to surreptitiously watch his wife put their son on the school bus. In the Fuller yard in northern Pennsylvania, children arrive for a school field trip on rail safety. After panning across some idling diesel locomotives under the opening credits, the film begins with scenes at two rail yards in different regions of Pennsylvania run by the Allegheny and West Virginia Railroad (AWVR).The synopsis below may give away important plot points.
