There Is a couple of these, if not all four, rotting away in Tigard, OR. This was 6 year old information.

Here is some info from espee.railfan.net: In 1977, SP sold 4 written off U25B's to Morrison Knudsen, for re-engining with Swiss built Sulzer 3000hp (derated to 2800 hp) V-12's. Not much was reused, only the trucks, traction motors, frame, main generator, cab and nose. The long hood was rebuilt 10 inches higher, and 4 inches wider to take the Sulzer engine. Had these units been successful, Espee had in mind rebuilding about 50 written off U25B's, as it turned out, they were not totally successful, and were set aside as soon as the economy got tough, in the early 1980's.

These were U25Bs rebuilt with Sulzer prime-movers. Didn't quite work out in the end.

Marc - As I recall, these were GE U25B's re-engined by Morrison-Knudsen with Sultzer prime movers.

SP U25 rebuilt by M-K with Sulzer engines rated at 2800hp. Also used imported radiator systems which were unable to cope with the local conditions. They did not last long in service.
