IAIS 513 HISTORY Rept Marks From To Notes IAIS 513 21 Jan 2010 Present

Notes:

• IAIS 513 is better known as the "Rock Island heritage unit". Rather than being painted in standard IAIS phase V, it instead received a black and red paint scheme similar to what the Rock Island had on various freight EMD F units and Alco FAs. In addition, it bears the name "Rock Island" on the side and the RI "beaver pelt" logo on the nose. For reporting purposes, it carries a small IAIS on the cab side.
• All of IAIS's ES44ACs were built to CSX's ES44AH "heavy" specification at 432,000 lbs, and includes the high traction software modifications.
• The unit was painted at Mid-America Car in Kansas City during December 2009 - January 2010.
• 513 arrived on IAIS and placed in service on 21 Jan 2010.
