Somebody can't spell! 
Front loco. and the one behind it have the same spelling error

The "Union Pacif" part of the name is on brighter yellow panels than
the "ific" part - and also several inches higher on the loco - so I
suspect side panels from a different loco have been installed.
The sign is correctly spelled on the loco in the background.
You can see this same engine (UP5720) in motion - sighns correct -
at http://www.youtube.com/watch?v=K0ngPDZw08k
Also he http://www.youtube.com/watch?v=LPUUmQercbw
It is a GE AC4400CW with Computerized Tractive Effort option - 4400 HP
AC traction motors built between 1993 and 2004. Union Pacific alne
owns 1338 of these locomotives.
AC indicates AC traction motors (with separate inverters for each
motor for speed control). The 4400 is the horsepower, the C indicates
6 axle trucks (in place of the B series 4 axle trucks) and the W
signifies the "americannsafety" or "wide" cab.
The same basic trainwas also built with 6000 HP as the AC6000CW
series.
See :
http://images.wikia.com/locomotive/i...W_OLS_logo.jpg
for an AC4400CW-CTE and note the location of the final "IFIC" of the
signage and imagine it on the opposite side. The "Operation
Lifesaver" and "we deliver" Are missing on the picture in question
Notice the size of the fuel tanks.... holy ****....
Plus, in very cold weather, some railroads leave these diesels on 24/7.
Breathe deep....
These hyooge diesels cannot navigate all track, even assuming the correck
gauge.
Ed H. should note that these diesel-ELECTRICS accelerate just fine off the
throttled diesel generator....
Heh, which bodes quite well for the plain ole otto-cycled AngstMobile, I"m
happy to say.
These diesel electrics also run hyoooge (often) Quincy air compressors, for
the train-line braking system.
Also inneresting is that in at least some diesel-electric designs, the
generator also acts as the starter motor for the diesel -- super cool, imo.
Personally, I think 6,000 hp in one unit might be a bit much. The torque at
the wheels is so high, there isn't really enough coefficient of friction to
take full advantage -- esp in the rain. Spinning steel wheels can quickly
put divets in rail, rendering it useless, dangerous.
Mechanically more efficienct -- esp on the couplers, rail, etc -- would be
to have several smaller diesels spread throughout the freight consist.
Unless the consist is SO large, so heavy, they need these 6,000 hp behemoths
spread throughout the consist.
Smaller utility diesels can have a mere 350 hp.... and what they can pull
is fukn amazing -- altho their capacity rapidly decreases up grades.
But a mere 1,000 hp can haul well over 1 million pounds, up grade.... altho
how fast is another issue.
Heh, sort of like the AngstMobile, with its get-me-TF-home backup genset....
LOL
