So what is this?

 

I believe those were new SD60M's with the then new "AC" traction motors back in '92 or so.

 

Thanks, Kurt. There was a passenger car after the 3 or 4 engines; probably taking measurements.

 

Flash,

Indeed, you captured the "birth of the AC locomotive revolution" there. Nice catch!

 

Those are the 3 test bed SD60MAC's that EMD built for testing of the AC systems. I think they are or were decomissioned after the testing.

The SD60MAC's were on BNSF's active roster until mid-1998. They were at the Transportation Technology Center in Colorado by July 1998 and remain there today.

 

Actually, there were four.........

 

I just checked and there were three in my picture: 9500, 9501, and 9502 here. The other is probably like a "control" unit to test changes?

 

The 9503 was delivered much later. Most of the testing was completed by that time. The units were used as demonstrators for a short time on other roads. When BN took delivery of the SD 70 MACs, they were placed in train service on the BN.
