Eastbound empty grainers are about as predictable as the tides thru Helena. 2+1 or 3+0 power configurations and about 100 cars. Saturday afternoon saw a train that was anything but typical. Three units on the point, two midtrain DPU, and one on the rear and about 150 cars. As the rear DPU rolled by they must have been doing at least 45mph, very impressive indeed. If this is the trend that would mean 2 of these trains could supplant 3 of the traditional configuration.
