With a rather cold winter moving into late 2010 and early 2011, I managed to get back to modeling the Revolution units. One frustration was finding some type of stand in hood latch for the access panels on the conductor side above the EFI cabinet. I happned on Details Associates EMD lift tabs. They were close enough with a little flush sanding. The SD75ME-CAT went to completion of major kitbashing and detailing soon after. Here is the SD40ME-CAT T-2 variant with major kitbashing complete. Also, I have started a SD40ME-CAT on a RTR Athearn SD40. The SD versions require a stretched two fan version of the GP60 squared off dynamics.  Great Work! I've always liked the "porches" on SD-40's, this is just a larger version. |

I'm digging the SD40ME-CAT unit. But I have a question.
Why the GP60 style DB hatch? Why not just stay with the hatch that comes with the unit?

If it were me the answer would be: because it looks cool. Lol. I've often imagined a modified or late phase SD40-2 with a GP60 DB hatch. I just think it would look cool.

Funny you say that cause I was going to say the same thing. I think it looks cool also.
I have an SD40-2 that I am going to do the same thing too. I took the DA kit (but I might try an Athearn one next time) and filled in the fan hole and drilled two holes for two fans like the standard SD series. It fits pretty good and looks good also.
It shows an upgrade from the usual and gives the engine a unique ness. Something to talk about.

I just noticed this thread myself.....I too am fooling around with a Proto 2000 SD50 I had in my parts box making up some kind of freelanced, eco-freindly  , franken-loco  for my home road to display and appease the Public Relations Dept  and tree huggers :-Sthat WE are trying to do something to help the environment. |

What is the snoots nose with the smoothe top and SD style DB hatch in the background??? That whole bench looks really cool  Sent from my GT-I9100 using proboards |

Since I first started this project, it has been pretty much shelved due to time and others taking the front seat. During this time, study of the Current EMD rebuild for CP rail and discussions with Anthony revealed some interesting questions that needed to be answered. The reason for all these wild iterations of the TGX Program is the march to meet the increasing EPA Emissions standards. Now the standard is approaching Tier 4 and just as the prototypes, I am struggling with designing a unit that emulates these real world changes. The obvious issue with the first design was a lack of radiator cooling capacity. Cooling the engine and exhaust is key to meeting the clean air standard, and the SD40ME-CAT required more. On the redesign, the radiator roof is bumped up a few more scale inches, to facilitate SD60 grilles and 48" high throughput Q-fans. The SD40ME-CAT is the least evasive rebuild, and as such horsepower is limited to around 3000hp. Also new is the access hatch to the intercooler control systems on the engineer side. The newer type dynamics are more compact and efficient, and interestingly enough, are now showing up on EMD ECO rebuilds. The cab is completely new, hinting it meets the new crash worthiness standard with the hard angles on the nose of the short hood. Also of note is the exhaust, which is redesigned to match Anthony Lorch's LEO project. The LEO line is actually a pre-cursor to the TGX program  Here is the updated drawing. |

Class 1 rebuilds only need to be Tier 1+ so no real need to chase Tier 4.

Could you not have extended the long hood and placed longer SD45-2 style radiators on there, maybe added a fourth cooling fan on the roof? I like what you've done, some imaginative stuff.

The EPA managed to get rebuilt locomotives under the umbrella of the Clean Air Act standard. The loopholes for rebuilds is closing. If you look at the current EMD ECO units for CP, you can see what I am talking about. Most states offering credits require units to meet the current (or soon to be current Tier 4 standard). It then becomes the best interest of rebuilders to offer something that will meet at least the current standard or the next one, just to be safe and guarantee a market as the Emissions standard changes. I think this year for example, any recapitalized unit will have to meet current emissions. Notice I say capital rebuild. Overhauled, repaired or capital rebuild (basically just renewing the locomotive to its original specifications) are not included yet. That is the only way you can now get around the standard. I am looking at this from a marketing standpoint. This is a remanufactured unit so it is covered by the Clean Air Act standard and must meet current EPA Tier requirements. This is not the only TGX Program Revolution Series model. This is only the base rebuild of a second generation SD type core.

Here is the mid-range Revolution Series Rebuild. The extra radiator length is taken from the typical SD third generation layout. The radiator is canted, just like the EMD SD70M phase 2. My twist is making the radiator look much like the old CNW SD45, a favorite of mine. This is not cosmentic as much as allowing for the change in the exhaust mainifold to not only silence the exhaust but to accomidate the extra requirements of the intercooler pipling. The mid-range horsepower unit prefers a SD45-2, Tunnel motor, SD50 or SD60 frame due to the longer length when compared to the 40 series frame. This rebuild is more evasive, more expensive and sees an increase in horsepower.  |

Pity the fool that has to change the electrical cabinet air filters...up and over the left side (AC rectifier?) box
