UP SD40s at the beginning
Author: masterphots

UP purchased the EMD SD40 test beds Nos. 434A-H,  which were used to test the 645 engine.  They were built on SD35 frames,  hence without the signature SD40 porch.  Here are images of the UP 3040,47, 46,41 lash-up at East Yard, Los Angeles on 4/6/66.

Love those silver trucks !  Here is the ex-EMD 434B at Taylor,PA. some 25 years later on 1/19/1992 as PLMX 3041 working as one of the many lease units at the time on the CP/D&H. Wonder if it is still around ?

Great series.  If these went by me I didn't realize their significance.  Thanks!

The last photo of the PLM unit sure looks like it's sitting in the rocks.

It ultimately became HLCX 6399 and was scrapped in 2010.

In my opinion, this is the best paint scheme UP ever used. They need to return to it!

Is the there a reason some have a flared long hood and others don't?

The first six got flares, the 3046-3047 didn't.

Nice historic units with their special character, and sure does look good with the cab slogan

A both truly excellent and historic photo series.
To quantify, SD35 was 5' shorter than SD40.
Thanks for the great photo posting.

Here is some history to go along with Masterphot's great photos.

I worked on these units many, many times in the 1970s, and they had very tight spaces between components. The spaces were increased a bit for the SD40s, and even more for the SD40-2s, making the later units much easier to work on.

Aye, aye capn'! Certainly one of my favorites. Today, one of the FEW things you can be depended on Uncle Pete for is that a desecrated flag will come rolling along real soon...
