Abstract: A hierarchy of procedures sets pacing schedules for trains operating in a railroad network. At a train level of the hierarchy, a network coordinator sends time windows to a train indicating when the train should arrive at or depart from a siding along its track. The time windows provide flexibility for the train to adjust its pace as needed, for example, to conserve fuel. At a territory level, if the train indicates that it cannot comply with the time windows, the coordinator evaluates and adjusts pacing schedules at least for other trains sharing the same track in the territory to avoid conflicts, again providing time windows for the trains to adjust their pace as needed. At a network level, the coordinator ensures that pacing schedules adjusted for a territory also meet time windows set for trains crossing a boundary into another territory in the network.
