The United States Rail Container Transport (COFC), including Trailer Container Transport (TOFC), developed rapidly after World War II. In 1973 its traffic reached a record high, accounting for 153.5 million vehicles. During the 1974-1975 recession, its volume dropped to 1.21 million cars. However, with the improvement of the economy, the volume of container traffic in 1976 began to rise again. In 1977, it reached 1,688,000 vehicles, which was also innovative. In 1978, it is estimated that the number of container loadings will approach 2 million vehicles for the first time.
