Unusual NS freight train

[nkalanaga]

I work south of Kenova, WV, and follow the NS mainline for ten miles or so.  Today I saw an oddity, which would probably get a lot of comments on a model railroad.

The train was a typical NS coal train, two units, and a mile or so of assorted NS/CR coal hoppers and gons.  The odd thing was the single-unit TTX well car with two 40' containers between the locos and the coal.  I've seen individual container cars in manifests, but never in a coal train.

Got a hot car that needs to get across the railroad?

Throw it on the next train heading that direction..

Is that the NS test rig?

I would venture a guess that it was a bad order picked off at a detector, fixed and this was the first train able to pick it up.

~Ian and Missaberoad:  Those would be my guesses as well, but it was an odd sight.  Maybe something do at a train show, on one of the big modular layouts.  It would probably attract attention.
