The Simpson Lumber locomotive in the "Trains" article.

ALL:

What is the heritage of the Simpson Lumber locomotive picture in the "Trains" article?

Does it have DB? The numbers are the same font and size that the BN used.

My magazine isn't beside me right now to check the number on the engine in question. But as of 1997, they still had SW1200's #1200 & 1201 that were bought new in 1956 and had dynamic braking.

In addition, they had 1955 built SW900 #900 with dynamic braking (Bought new?) and SW1200 #1202 bought 2nd hand from BN in 1983 which doesn't show any sign that I can see of having been rebuilt with dynamic braking capabilities (Although it's not obvious to me that the SW900 has it, yet it's listed as such).

And lastly, there's Alco S1 #600 bought from the Tacoma Municipal Belt Line in 1979. While Trains has it down as a S1, The Diesel Shop has it listed as a S3 despite its 1949 build date. So perhaps it might've gotten its original blunt trucks replaced with AAR Type A's at some point in its life. 

That said, it's also listed as ex Humble Oil and according to the Wikipedia list of original S1/S3 owners, they only bought a single S3. And pictures from it being trucked away after being donated for preservation in 2005 show the later truck design, with a 1950 build date in the write-up.

So I suspect that Trains misidentified it in their story about Simpson in 1997 and that The Diesel Shop has the year that she was ordered listed rather than the correct 1950 build date.

SW8's and SW900's have V-8's so the d/b can be tucked into the switcher hood rather than on top like an SW1200, which has a V-12.
