U.S. rail volumes in June 2021 and Q2 2021 were consistent with an economy that’s growing but has more growing to do. Total U.S. carloads in June 2021 and Q2 2021 were up 19.1% and 23.8%, respectively, over the same periods in 2020 as easy comps led to big year-over-year percentage gains. That said, total carloads in Q2 2021 were the most for any quarter since Q4 2019.
...
On the intermodal side, U.S. originations in Q2 2021 were the most ever for a quarter, and intermodal volume in the first six months of 2021 were the most ever for the first six months of a year.
