GSCX Leaser on the BNSF - Never seen this before

[Amtrak31]

I was Train Watching on the BNSF today, and an autorack came through with a UP Dash 8, an NS High Hood SD40-2, and a GSCX Leaser SD40-2. Has anyone ever seen a GSCX? This was my first time. Can somebody please tell me what it stands for? Thanks.

GSCX stands for GATX Capital Corporation, a division of GATX, and their fleet is mostly all SD40-2's, many of Milwaukee and Missouri Pacific heritage.
