TheEMD F69PHAC was an experimentallocomotive built in 1989 in a joint venture between EMD andSiemens. It was designed to test AC locomotive technology. Only two examples of this locomotive were made. The engine used the same carbody as theEMD F40PHM-2, with just a few spotting differences.[1]

They were built for theUnited States Department of Transportation and loaned toAmtrak in 1990, sporting Phase III paint. They were returned to EMD and later used with theGermanICE train demonstration that was on loan to Amtrak in 1992–1993. They were repainted in ICE paint. The two F69PHAC locomotives were again returned to EMD, where they were finally retired in 1999. Both of the locomotives still exist in ascrap yard, more specifically National Railway Equipment, inMount Vernon, Illinois, stripped of numerous parts.[2][3]
