Intermodal (i.e., cargo container) shipping is booming. In 2013, intermodal volume on the major railroads totaled 12.8 million containers, the highest on record.[1] Demand for frac sand — industrial sand used in hydraulic fracturing — continues to rise dramatically due to the rapid expansion of domestic oil and gas production. Most of that sand is shipped by rail: Between 2010 and 2013, annual shipments of industrial sand doubled to approximately 375,000 carloads, with frac sand as the primary driver.[2] And the amount of crude oil being shipped by rail continues to rise at a steady pace: over 407,000 carloads in 2013, and over 229,000 carloads in the first half of 2014, compared with only 9,500 carloads in 2008.[3]...
