IAIS 512 HISTORY Rept Marks From To Notes IAIS 512 29 Oct 2009 Present

Notes:

• All of IAIS's ES44ACs were built to CSX's ES44AH "heavy" specification at 432,000 lbs, and includes the high traction software modifications.
• 512 was actually built and painted as CSXT 950 before CSX cancelled the order. The unit was then sold to IAIS and moved to Mid-America Car in Kansas City for paint, arriving on 3 Oct 2009 with its CSX markings covered with grey primer.
• Unlike the first order (500-511), 512 and 513 have the door on the engineer's side of the cab.
• 512 arrived on IAIS and placed in service on 29 Oct 2008.
