I saw this the other day by my house in the NEW switching and storage yard by my house. I was going to snap some photos, but Chuck beat me to it;

Good morning,

Here’s a couple recent photos taken near your place.

It shows military tracked cranes.

In my love of trains, seeing military equipment on rail cars is an added bonus.

I refer this area south of 14th Street as the south rail yard.

Don’t know what BNSF calls it.

I suspect this area will see more activity after the downtown yard removal.

Yeah, you are not kidding. (click to enlarge)

Here are photos I shot in 1964 of the downtown Sioux Falls rail yard.  I was in 9th grade at the time.  These were shot with a Kodak Brownie Starflash 127 so the resolution is not real good.  The rail yard was a busy place in those days.  Watching the action was exciting. At this time there was only the 10th street viaduct.  – Charles Luden
