Smaller railroads had operating revenues of between $20 million and $250 million (Class II) or less than $20 million (Class III) in 1991 (see “Class I Railways”). Switching or Terminal Train A small railway that provides pickup and delivery services to railway customers and/or trains for line trains in a terminal. Short-Line A small railway with fewer miles of track than a “regional” railway. A short distance may be “neutral” or independent, in the possession of a major railway, a railway customer, a government agency or a major railway, by a “paper barrier”.” The four “big” Class I railways are BNSF, CSX, NS and UP and handle more than 95 per cent of the national traffic. Commercial access by the railway, which owns the tracks for the installation of the rail customer, as well as any other railway that can actually offer a service through agreements such as: Build-Out When a “captive” customer creates a “rail rail competition” by building a new railway line to a second railway. An “installation” occurs when a railway builds a new line to reach one or more rail customers bound by another railway. Transportation When a railway transports traffic on its own line on behalf of another railway. The second railway pays a fee for commercial access to customer traffic, but does not operate its own trains on the tracks of the first railway, which is the main distinction between “transportation” and “track rights.” The proposal only applies to Class I railways, but the industry is so resilient that Congress was only able to pass rail reform legislation last year, after omitting an alternative provision that appeared in an earlier version of the measure. A switching and terminal train is a freight rail company whose primary objective is to provide local switching services or to own and operate a terminal facility. Switching is a type of operation within the boundaries of a yard. It generally consists of the assembly and dismantling of trains, the storage and classification of cars, respect for industries within the boundaries of shipyards and other related purposes. These movements are carried out according to special rules of slow-speed yards.
 The Internal Revenue Service provides tax incentives to such businesses.  They can also be created when a major railway abandons an unprofitable line and a short train takes over the operation to connect shippers to the largest company.
