Southernmost Southern Pacific
You can’t get more “southern” on the Southern Pacific than Brownsville, Texas. Brownsville was the end of the line for the SP in South Texas. Just a few miles south of the SP’s small yard was the International Bridge via which the SP would interchange traffic with the NdeM (National Railway of Mexico).
This wasn’t the only time SP 3361 was in the Valley. On rr-fallenflags.org, Bob Harrold snapped a photo of it in McAllen TX in August 1976.
Going through slides I’ve noticed the same units pop up regularly. I have shots of the 3361 working in Harlingen also…
Harlingen? I do remember interlocking tower 138 being there before it’s removal in 1994. I hope so see pics of 3361 and any other units in Harlingen.
