(2) To allow an easy comparison of permissible in-service loading (or rating) over the life of a bridge with the loads used in their original design, and to compare the effect of different engine and car loads for either design or rating, the railroad industry kept the basic Cooper load configuration and used it to. API 1102 for railroad crossing program is based on the design methodology that has been used in analyzing existing uncased pipelines and designing new uncased pipelines that cross beneath railroads. This API design methodology relates to the train engine (E-80) which is the heaviest load: Steel pipelines installed using trenchless construction methods, such as auger boring, with the crossing.

The American Railway Engineering and Maintenance of Way Association (AREMA) recommends a Cooper E80 loading with axle loads and axle spacing as shown in Illustration 4.19, Based on a uniform load distribution at the bottom of the ties and through the soil mass, the live load transmitted to a pipe underground is computed by the equation: WL..
