Gary,
I am guessing you are using some sort of SP internal roster for your information? I say this because you have
GE down twice for builder of a things SP did in house. I am guessing that GE might be an internal company
code for Sacramento GEneral Shops, but am not certain of this.

The first TEBU #1600, was built by MK from ex UP U25B #634; SP took one look and said they could do that themselves.
They took U25's dit up to Sac as needed to be stripped and rebuilt, #1601 through #1613 are the results of this program.

I got this info from the office of chief Mechanical officier, Southern Pacific headquarters, San Francisco.

Gary,

Was there anything in you RR paperwork that gave tractive effort estimates on these TEBU's, or anything else they had? I know someplace, a formula exists for determing HP or tractive effort per axle, or something used to determine how to pull a given weight over a specific route.

I mean, I have seen those massive printouts that have all the cars in a train, the weight of each car, loaded or empty, whats in the cars, etc..

They just did not add engines until they guessed they had enough HP; or did they? I have a series of about 20+ slides that show a WCLAY start out around the balloon track, then finally stall in run 8; I seem to remember a 45T-2 and a U33C on the point. They should have had 4 SD9's on that train; roughly the same HP, but more traction motors that can run all day at 8-10 mph without giving up. The tunnel motor probably red lined and it looked like the GE was doing all the work at the end; I never found out.
