Last week, Inside Energy reported that about 408,000 carloads and 39 million tons of crude oil originated on United States railroads in 2013. It’s a lot of oil, and it’s raising a lot of questions about safety. There are a lot of things we still don’t know about crude-by-rail, and Inside Energy is drilling into the details. How many railroad cars is that? An average of 1,119 carloads a day.
