Daniel,
the 1st order of U.P. GP9Bs were PHS-1,some even had GP7
style Handrail Stantions.
Diesel Era just had a good article on the PRR GP9Bs,it will be
awhile before they get to the U.P. versions,some rebuilt to
"Omaha GP20s" by U.P.,others by EMD.then some were modified
to run with Turbines,others were rebuilt back to sort of regular
GP9Bs,but kept the big fuel tanks.
best to know what year the units will be modeled as.
