BNSF cancelled the tank car order.

Relatively useless artice that only contains SOME truth. UP's oil by rail traffic is down quite a bit but that's because less and less Bakken crude is going south to Texas and Louisiana (BNSF and CP had been interchanging lots of Bakken crude oil trains to UP at Kansas City for movement to the Gulf Coast. Now not so much). Plus, price wise, Bakken oil can no longer compete against Eagle Ford crude oil from Texas in those two states. Naturally the article says nothing about this.

Contrary to what the article says frac sand traffic isn't down that much, in general, (yet). That will probably change to some degree during the summer but for now no. Wisconsin, the leading frac sand producing state, is starting to feel the effects but for a different reason. Competition. Oil producers are looking to buy frac sand that is much closer to the well heads. Thats why producers in the Permian Basin are beginning to buy more frac sand from mines in Missouri - lower transportation costs. The article doens't say anything about that either.
