In the early 1990s Amtrak was testing two foreign train sets. The German ICE and the Swedish X2000. Believed to be the F69PHACs' last assignment, they were returned to EMD shortly after the end of the tour. The ICE was in Metroliner Service on the NEC until late 1993 when it was returned to Germany. I think they were to the power for the ill fated Marlboro train.
Current rumor is they are going to be scrapped.
Tapping Siemens' experience in the development and application of A.C. traction technology in Europe, EMD took a commanding lead in the race to develop a North American A.C. locomotive. By 1987, EMD had its own A.C. test bed on the road.
