For intermodal, 2021 was the tale of two halves. The first six months of 2021 saw record-breaking highs, but volume cooled in the second half as global supply chain challenges persisted. For all of 2021, U.S. railroads originated 14.14 million containers and trailers — up 5.1% over 2020, up 3.4% over 2019, and the second most ever for a full year. Only 2018’s 14.47 million was higher.
