Steam & Excursion > Who is the group that is restoring the Centennial from SD?

I forgot their name, but a month to maybe 3 months ago they came out and said they were going to restore it.

Thanks In Advance

Midwest Overland Rail Preservation Society. (Not to be confused with the Midwest Rail Preservation Society over in Cleveland, Ohio - note the lack of "Overland.") Check out mopxrr.org; they have a page there all about it labelled "Saving the Centennial."

Tall order but they have some very odd equipment and worth saving do hope it works out for them.

Thank you for giving me the information! 

2-SD40s, one frame...
However their electrical systems pre-date the advances of the  "dash-2" 
generation...  Dash-2 electrical controls were earlier, modularized electrical
control systems, which predated the use of an on-board computer-cootrolled,
 electronics of all operating components and systems.

  Dash-2 locos were a more 'modern' variant of electrical control components,
   with printed circuit-boards in the electrical cabinets.  
 
   Today's electrical equipment is essentially equipped  with all solid-state,
   on-board computers, programmed for individual models: 4-traction motors
   vs. 6-motors, various engine operating parameters, safety devices,
   emission compliant settings, etc.   One computer model hardware:
    customized & programmed and up-dated .... across a whole fleet.
    
    The manufacturer supplies the software + updates to the onboard computers.
     Every computer-equipped loco is in the manufacturer's software at the vendor's
     computer base location, along with the failures, troubles, warranty coverage and 
     maintenance-routines histoy of each loco.

I visited it in June and it didnt appear that any efforts had been made to ship it out. Has anything changed?

Just my feeling, but I don't think anything will change. This "group" seems suspect

I've always read that the DDA40X was 2 GP40's mounted on one frame hence the DD40 designation.
 The X means Experimental and they were indeed built with modular electronics...they were the test bed for the Dash-2 lineup electronics.

I'd like to know more about the picture that I seen taken inside EMD LaGrange that showed a SD45 mounted on a pair of DDA40X trucks!

You are correct.

Just from memory, those would be the units for a South American country (Brazil?).

Model DDM45. Meter gauge; 83 built according to Wikipedia.

Hey thanks as I've been looking for awhile as to what those were and the DDM45 model designation makes total sense!

Any pictures of the traction motors that were used on 
meter-gauge axles?   The back-to-back-space between the wheels
on the axle must be TINY!  ( plus, you've got the gear on the axle!) 

The T/Ms gotta' be less powerful than the "standard" motors.

If I recall, that's why the prime mover horsepower rating was unchanged in those meter-gauge conversions; the smaller motors were rated at lower horsepower so the weight was distributed over additional axles, but there was no additional capacity over a standard gauge unit.
