Train Scheduling,rain driver or crew requirements, the service received by customers, impacts locomotive requirements, and is a large determinant of network efficiency. This chapter focuses on the role of the train schedules, and describes the data elements making up a train schedule, the process of designing the tr

Locomotive Scheduling Problem,g a set of locomotives to each train so that the assignment satisfies a variety of business constraints and minimizes the total scheduling cost. Major US railroad companies have several billions of dollars of capital investment in locomotives. Thus, solving this problem effectively is of critical im

Simulation of Line of Road Operations,cuses on the management of line of road operations. Railroad management devotes the largest amount of analytic effort to this discipline, and tools exist for its analysis. Most railroads and many consulting firms have staffs dedicated to using tools to analyze line of road operation and justify capi

Car Scheduling/Trip Planning,nd the trains that will move those blocks. The resultant car schedules or trip plans are used to project future workloads at yards, expected train sizes, as a means to manage individual shipments and ensure that they are routed correctly, and as a way to provide estimated delivery times to customers

Crew Scheduling Problem,d trade-union work rules. Train crew work together to move a train from its origin to its destination. As the train travels over its route, it goes through numerous crew districts. In each crew district, the train is manned by an engineer and a conductor who are qualified to operate the train within

Empty Railcar Distribution,e, the railroad must deliver a rail-owned empty railcar (such as a box car, gondola, or hopper depending on the commodity) to the origin of the shipper to begin loading. (This process does not apply to private fleets owned and managed by the shipper, as is common for some car types such as tank cars

Network Analysis and Simulation,isions are often made separately without the ability to easily understand the impact of one decision on another. For example, if a new train is added, and another removed, will the expected connections of the traffic from those trains to subsequent trains still be acceptable, will the network capaci
