AAA I tarot Osseo 90* AAR fir Goal Coal volumes account for roughly one third of U.S. carloads (ex-intermodal) but just 10% of Canadian carloads (ex-intermodal). Cumulatively in NA. coal accounts for a little over one quarter of all carloads (ex-intermodal) which is down from just under 40% in 2010. Much of this decline is due to increased supply of natural gas, with 2016 becoming the first year that natural gas has exceeded coal in U.S. electricity generation on an annual basis.

The long-term trend is undeniable, however, resulting from the drastic decline in natural gas prices following the hydraulic fracturing-fueled U.S. shale boom. To put the move in context, the price of natural gas was roughly seven times more expensive than coal ten years ago (October 2015 MIT study), and today those prices are in parity with coal (i
