EMD F3
The EMD F3 is a 1,500-horsepower (1,100 kW) B-B freight- and passenger-hauling carbody diesel locomotive produced between July 1945 and February 1949 by General Motors’ Electro-Motive Division. Final assembly was at GM-EMD's La Grange, Illinois plant. A total of 1,111 cab-equipped lead A units and 696 cabless booster B units were built.
The F3 was the third model in GM-EMD's highly successful F-unit series of cab unit diesel locomotives, and it was the second most produced of the series.

It has improved contact connection with the light board/decoder
I just added decoders to my Frisco GP38's and I want to say THANK YOU for the improved contact connection with the light board/decoder. The decoder is now truly drop-in and you can actually see exactly where the contacts come together. Bravo Zulu AZL!

Removing the shell
Removing the shell
Hold the fuel tank and wiggle the shell gently until it comes free.
The wipers can fall out easily when the locomotive is disassmbled, a drop of white clue can secure them, a hint from the AZL Forum
Installing the optional plow
Remove the front truck with coupler. Use a small flathead screwdriver to gently pry off the truck. Do this at the rear of the truck. The truck will then pop out off the chassis. With the truck out, simply snap the truck without the coupler in place. Swivel to test to make sure it is moving freely and not catching on the electrical contacts.
Replacing the LED's
The yellow LED's were replaced by sunny white (warmweiss) LED's which give a more natural light.
Digitalizing
The GP7 was digitalized with the TCS Z2 decoder.
