What the heck is this??? 2

I caught this train heading southbound on the BNSF line with 2 NS and 1 unpainted/unlettered. What is it, could it be NS or BNSF in route to being painted? Enjoy-


The # is 2636

It is one of NS’s new SD70Ms with the flared radiators. They have been getting a lot of them still in primer, just like some of their Dash 9s.

Looks like a Rail power Products undecoreated shell with Athearn chassis.
