Western Pacific Railroad EMD model GP-35 # 3009 at Stockton California in 1974. From the internet.

Even though I was born and raised in the city of Chicago Illinois, Believe it or not, one of My personal all time favorite North American railroads was the western Pacific.

The Western Pacific existed from 1910 until it was acquired through merger by the Union Pacific in the year 1982.

I found this photo on the internet recently.
Seen here at Stockton California way back in 1974, are EMD model GP-35 roadswitchers wearing the 1960's era orange and silver color scheme. While being a very attractive and eye catching color scheme, it unfortunately did not weather well in the long run.
It was replaced with a dark green and orange lettering color scheme by the early 1970's.

The western Pacific operated from Northern California to the States of Nevada and Utah. It was a very unique and colorful railroad.
