      Not sure why the above link will not post correctly (just copy and paste URL and it works ) that will give you lots of information.

      Rooster,

       

        Those air filters in your diagram are on the engineer's side ahead of the fuel tank.   What I'm researching is on the fireman's side behind the tank.  As far as I can tell, the UP added whatever it is when they shopped the locos for the N conversions.

       

      Here is a better photo:

       

      Thanks for the rest of the links, they are really useful.

      From UtahRails.net:

      Beginning with the completion of UP 1550 on May 4, 2010, Union Pacific began modifying its refurbished SD40-2 locomotives with an updated and modern control system known as NEXSYS, supplied by ZTR Control Systems. each locomotive was given a formal completion date, retaining its original SD40-2 model desigation. The modification program continued from early May 2010 through early July 2011. At that time, with the completion of UP 1629 on July 8, 2011, UP began using a new model designation: SD40N, denoting the railroad's "SD40-2 Modernization Program."In addition to receiving reconditioned components (main generator, traction motors, air compressor, air brake equipment, etc.) the SD40N units are receiving SmartStart systems, also from ZTR. The rebuild also includes refurbished cabs with new doors and seals, air conditioning, Positive Train Control capability, and completely rewired electrical cabinets. A major part of the rebuild is the installation of remanufactured engines with all applicable modifications to comply with federal government CFR Part 1033 emissions standards.UP 1613 was completed with the NEXSYS system and was renumbered from UP 3372 on July 5, 2011, but carried the earlier SD40-2 designation, with a note that it was part of the modernization program. After the SD40N model designation was adopted in early July 2011, all previous units completed as part of the modernization program, going back to the first one, UP 1550, completed on May 4, 2010, were re-designated as SD40N units.The 'N' part of the designation comes from UP's use of the NEXSYS control system from ZTR Control Systems, replacing the older Dash 2 component cards and control systems (ZTR web site).As of early 2015, the number series for the SD40N units are UP 1550-1782. Also, many of the units in UP 1800 and 1900 series are designated as SD40N. Other units in the 1800 and 1900 series have been renumbered pending actual rebuild, and are labeled as SD40-2. This is to clear their 3000-series numbers for use by UP's 8000-8308 class SD9043MACs, which in turn are being renumbered to clear their 8000-series numbers for use by new GE units.

      Hope this helps

      -Dave

       

       

      Not real sure Chris but it sorta looks like part of the air system.

      I'll second the air dryer. UP typically installs these on all of their power. They make a very annoying noise, tattttt, tattttt, pishhhh, tattttttt, tattttt,...

      I found the article on Utahrails.net last night so I contacted ZTR.  A fella named Peter told me they didn't install it but he gave me an idea of what it might be.  Googled around and found the Graham-White logo match.

      That's an odd place to put a hair dryer. But then I don't really understand all the fuss over them newfangled, cantankerous, unproven diesel-lectric thangs anyway.

      They are odd to me to Maynard.  That is why I'm building them to travel with.  Figured I would disgrace other people's layouts with dismals, not my own.  If I wanted to go full rudeness, I would bring something Amtrak.

      And that there is why I run Penn Central, and Tyco trains on the NMRA set up. When they comment that the Tyco stuff doesn't have KaDee couplers, I remind them them that X2F horn hook coupler was the NMRA standard at one time.

      First unit has been dipped and stripped.  This will end up being #1971.  I won't do the second unit until this one is done, just in case I need a reference on how it goes back together.   I have a little paint in the tight spots left that I will use a soda blaster to remove.

      Hi Chris 

      What did you use to strip the paint?

       

      Thanks

      Colin,

       

      Soak it in 91% isopropy Alcohol and brush it off with a stiff (not wire) brush.   Works really well.

      You are hardly an amateur.   How is the new loco coming?

      Chris, I'm waiting for you to catch up.

       

      I added some detail to the frame skirt, painted it, and have most of the reflective striping complete. The cab/nose is almost ready for paint. I'll probably post some photos once that is done.

      Now that summer has finally arrived, I plan on spending most of my time outside, so work will be slow for the next few months. Time to lay track.

       

      Shane
