9-graph. Class I rail network with volume of shipment in the United States.
Line Corporation, and Union Pacific Railroad. Fig. 1.10 shows the Class I rail network in the United States with volume of freight movements. A regional railroad is a line haul railroad with at least 350 miles (560 km) and/ or revenue between $40 million and the Class I threshold. There were 33 regional railroads in 2006. Most have between 75 and 500 employees. Local line haul railroads operate less than 350 miles (560 km) and earn less than $40 million per year (most earn less than $5 million per year). In 2006, there were 323 local line haul railroads. They generally perform point-to-point service over short distances.
Rail terminals, often known as intermodal rail terminals, serve critical roles in the rail transportation system. Three major components interact in rail terminal operations: rail track operations, container storage yard (see Fig. 1.11) operations, and gate operations. The purpose is to ensure that each operation interacts efficiently with the other since a delay with one operation will have impacts on the others. For instance, a problem with storage yard operations will create delays both at the rail track and gate operations and have an impact on the terminal productivity and the quality of its services.
Railroads are the most expensive component of a rail transportation system. Railroads are permanent roads comprised of lines of rails fixed to ties and laid on roadbeds that provide a track for railcars drawn by locomotives or propelled by self-contained motors. Railroads limit the movement of railcars and hence the freight movement. Switching and terminal (S&T) carriers are railroads that primarily provide switching and/or terminal services, regardless of revenue. They perform pickup and delivery services within a certain area
Due to the huge investment need in rail transportation system, the connection to freight points is limited. Once the investment is made, the operating costs are reasonable and comparative to truck mode. These operating costs are correlated to the central location of the rail hubs usually located within urban areas. These operating costs can also be measured in the rail capital investment and annual maintenance fees associated with construction and upkeep. Secondly, rail transportation is constrained by physical geography.
