my ESPEE MODELERS ARCHIVE
California's Railroad to the U.S. 1861 - 1996
Southern Pacific GP20E/R
SP 4100 - 4125
26 units rebuilt
These units were all written off by 1995, and no longer appear on the Roster...
A major point to watch for, is that there are/were 2 different rebuilds:
The 645 re-engined units, have a paper air filter and 2 exhausts, 1 each side if the dynamic fan, the 567 turbo'ed units retain the single exhaust stack.
As the photo shows above, and some texts hint at, likely #4100 and 4101 went back to have the 567 turbo engine, changed to a non-turbo 645.
