Sixty six cars back in the train, after the freight, and ahead of the 15 two unit autoracks and 15 stack platforms was this little surprise. Not the DPU itself so much-theyre fairly common on most trains, and the Q trains typically get them mid train like this, but that its a unit that was once a common sight, and now is not seen much. The DPU today was an SD 70MAC, looking good in the snow.
