Train size and tonnage is in description, Main 1 as its called is 4 miles long......this train had 2 grade crossings blocked and a couple miles ahead of him was NS 122 which was another monster who had another crossing blocked.
Was this two trains, coupled? Or were 4022 and partner in-train (manned) helpers? Looked cool, coming out of that fog.
The mid train power (called DPU or distributed power) is controlled by the lead motor in this case the 8184, this is also just 1 train.
