Freight railroads make money based on the weight of freight and the distance traveled. European railways don't make as much money hauling freight as their U.S. Stephenson had been working with various railways used in British mines and settled on what is now the standard gauge. Now that we have the mechanics down, let's see how they fit together to move packages and people. In many cases, railroad tracks are elevated above the surrounding ground and have drainage systems to remove water.

­Steel tracks can be straight or curved to steer the train since steel is easily bent into shape. A railroad track consists of two parallel steel rails set a fixed distance apart, called the gauge. The rails are connected to each other by railroad ties (called sleepers in Europe), which may be made of wood or concrete. The ties "float" on the ballast and the weight of the track keeps them stabilized. The ties are set into the loose gravel or ballast.

Ballast often consists of loose stones that help transfer the load to the underlying foundation. Depending upon the topography, some curves may be slightly angled or banked to help the train stay on the track as it negotiates the curve.

Once a customer contacts the company for more information, he/she is assigned a personal liaison to help with the transaction. To learn more about related subjects, such as the brain and how it is studied, read the links on the next page.

On the passenger front, however, European railroads are millions of meters ahead, as you'll read about next. Local linehaul freight railroads have revenues less than $40 million and operate fewer than 350 miles of track. Many railroad stations have switching yards where trains are assembled and moved onto various tracks. Switching and z grills pellet grill reviews terminal (S&T) railroads don't provide point-to-point transportation but rather provide switching services. While railroads own some of the thousands of freight cars used, car companies and other shippers actually own most of them.

In 1970, Congress created Amtrak to take over passenger services from the freight railroad companies. Congress could either deregulate the railroads or nationalize them.

Regional freight railroads check in with revenues between $40 million and $346.8 million. Since the act was passed, railroads have become more competitive and have increased their revenues and volume of traffic significantly. The Staggers Rail Act of 1980 gave the railroads the freedom to determine the routes of transportation, set rates for moving freight and streamline procedures for sale of rail lines.

Some companies in this class include CSX Transportation, Norfolk Southern and Union Pacific Railroad. The act did set maximum rates that railroads could charge and procedures to prevent abuses by railroad companies. Furthermore, U.S. freight railroad companies are privately owned and operated, with no government subsidies. Land grants by the federal government to the railroads in the 1800s allowed the railroads to own the tracks. They pick up and deliver cars within an area, usually for local linehaul railroads.

At various points along the track, rails may have switches, which can move a train from one track to another.
