Russian Video of tanks pulling back from Ukraine Border.

I watched the video.  It shows a couple of unfamiliar diesel engines, Russian design and manufacture perhaps.  Followed by a lot of flat cars.  Each flat car has one tank loaded onto it.  The video view is at pretty long range for a side of the train shot.  The train goes thru a steel arch bridge.  The bridge steel is all pink, a very unusual color for a steel bridge.  No rivets showing.

   I thought the whole video clip looked like a model train layout.
