Investopedia: June's Rail Traffic A Bit Of History Repeated
Rail traffic data, as reported by the Association of American Railroads'
"Rail Time Indicators," continues to show sluggish, but still very real
growth in the industrial economy of the United States. Conditions are
not great, as weaker coal and grain demand continue to impact total
volume, but they are at least supportive of a cautious optimism on the
overall U.S. economy.
