Hinkle Joe, you still on here? Wondering what's up with yesterday's potash out of Eastport (should be through Hinkle this morning) with three units up front and three mid-train instead of the usual 2+2. My first guess would be better air flow through the train in cold weather, but my next guess is that three units won't pump air from mid-train any faster than the usual two. My third guess would be simple pulling power, since there have been a number of stalls on Shiloh Hill lately, plus half a foot or more of new snow over the weekend.
