Moreover, the ability of a given bridge to handle prolonged rail traffic also decreases as wheel loads increase. [10] The axle load is twice the wheel load.
These were self-propelled with a continuous-track suspension chassis of substantial length to maneuver into a firing position over a short range, but depended on a pair of purpose-designed Schnabel cars for long-range transport by rail. [4] The same system was also used at the same time for the rail transport of the French FCM 2C super-heavy ...

Rail intermodal traffic tripled between 1980 and 2002, according to the Association of American Railroads (AAR), from 3.1 million trailers and containers to 9.3 million. Large investments were made in intermodal freight projects. An example was the US$740 million Port of Oakland intermodal rail facility begun in the late 1980s. [2] [3]
