Thursday mourning at Sullivan,IL @ 3:45 am was a local with the UP 2581. This unit was origanally a GP-40. It sounds like a GP-38. Did the UP de-turbo this unit? If so was this part of a group of down grades?

The rebuild to GP38-2 standards included, among other things, the replacement of its orignal 3000 h.p. turbocharged EMD 645E3 prime mover, with a 2000 h.p. EMD 645, thus giving it that GP38 "sound" you had noticed...
