And then, on another day, I chanced to encounter a wonderful triumvirate of SD59MX locomotives on a side track whilst I bopped around the Roseville Yard:
The SD59MX -- of which there are three -- the 9900, the 9911 and the 9922 -- was originally built as an SD60M. Three units were converted to the newest enviro-compliant strictures and then re-named as SD59MX -- SD for its three-axle trucks, 59 for its similarity to an SD60, M due to its comfort cab, and X for experimental.
That said, there is this photograph:
Information about the SD59MX here.
The EMD SD59M-2, more commonly referred to as the SD59MX, is one of the rarest locomotives in the Union Pacific motive power fleet. SD59M-2s are remanufactured SD60Ms.
- Wide-nose, so far only the later two-window wide nose rather than the earlier three-window "tri-clops" wide nose and none of the traditional 40 Series cab SD60s have been converted.
- Slightly slanted air intakes.
- High-adhesion HT-C trucks, reused from the "donor" SD60M, rather than the newer "radial" or "bolsterless" trucks. Nearly all SD40-2s and SD50s used the same truck.
- Safety fuel tank like that found on current SD70Ms.
That said, my tour continued, as documented here on video:
This was an active day at the Roseville Yard.
Amtrak's #5 westbound pounded through the yard, and any number of other freight locomotives were featured in and around the locomotive maintenance sheds and the drop pits.
Here, a D90 traction motor awaits replacement for an EMD SD70M.
And that the discoveries are rated and beyond.
Below, a GE locomotive reveals its under-cab under-HVAC-and-air guts:
Here, an overview of the J.R. Davis Roseville Yard:

In the heat of the moment, the bulk of these photographs were taken during the summer in 100-degree inspiration.
