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.


All of them do it. They use water instead of antifreeze and cannot
allow it to freeze.


Well, I don't know about water. The diesels I'm familiar with use
antifreeze. Why would diesels, big or small, use pure water?? For a variety
of reasons, corrosion just one among them.

The main reason, afaict, is like trucks: cold-weather starting of diesel
fuel. The only reason not to leave the engine running would be electric
heat for, well, everything fuel related, which might burn more energy than
letting the engine idle.


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.


And gentle for the motor.


Why especially gentle?? I figgered it was pure economy of function.
