Some of my friends have been arguing about whether or not an SD45T-2 is still an SD45. I say YES, because its still an SD45, just with specially built parts.
But many people are flaming us, claiming they look different, therefore they arent SD45’s.
I used this analogy: Do you call a firefighter American, or a fire fighter? A firefighter who happens to be American?
Please help me out on this one.
Thanks.
Well…put me on the list of people who don’t understand the question.[:I]

The air-intakes on the EMDSD45 design are on top of the locomotive, witch normally is not a problem.But when working upgrade through high-altitude tunnes, the design results in very hot air being drawn into the engine, which can cause overheating that forces the locomotive to reduce power in order to protect itself. Consequently, performance suffers.
EMD built a unique fleet of 20-cylinder locomotive with there air-intakes relocated at midpoint above the rear truck. That modification improved power output in the Siera tunnels by as much as 20 percent. The new model was designated SD45T-2
It is true that the “tunnel motor” modification increased the cooling capacity of the SD45-2 and SD40-2. It is not true that the modification makes use of air temperature differences between the top and bottom of the tunnel. There is no significant difference in the air temperature between the top and bottom of the tunnel. The revised cooling fan arrangement in the SD45T-2 and SD40T-2 provided greater heat transfer rate between the radiator and the atmosphere. Where the air is drawn from – high or low – is irrelevant.

groan…
an SD45 is an SD45
an SD45T-2 is an SD45T-2
an SD45T-2 is not an SD45.
it IS part of the SD45 SERIES!
Thats the argument.
yeah…
Itsa big heavy (Tunnel motors were ballasted extra heavy - Kinda funny to wach four of 'em chew up 100 # rail on the Kyle) 20 cylinder, six axle monster?
Um, not to further confuse this, but I’d argue it’s part of the SD45-2 series, not the SD45 series, and that Dash2 is the division mark. The SD45T-2 is an SD45-2 with a different fan/radiator arangement. It’s not an SD45.
An SD45 T-2 is an SD45-2.
An SD45-2 is not an SD45.
Same thing as a GP40-2 is not a GP40.
good point. i dont consider SD40-2s to be SD40s either
You’re an idiot.
The SD40-2s are SD40’s. Let me point difference for you. Electrical. They ride on the same frame and everything. The only difference updated electrical.
So what is your problem. You obviously have know idea what you are talking about. There is virtually no difference in the SD40 and -2 models. Try reading and talking to some of the representatives at some of these companies.

Someone check the frames because the Dash Twos are about three feet longer. There is a reference on Don Stracks Utah Rails site for the SD40-2 and SD40T-2. I have to agree with Atmo, he may not be the Lord, but he is right, SD40s and SD40-2 are not the same.
On Craig Rutherford’s Diesel Shop website you can find the overall dimensions for the SD40 and SD40-2. Just click on http://www.thedieselshop.us/DataEMDIndexRS.HTML and then go to the respective models. The performance characteristics are listed as the same for TE, but the SD40-2 is three feet two inches longer overall than the SD40. James you need to learn to attribute your rants. Simply stating a rail told you something does not necessarily make it so.
I know this wasn’t pointed at me, but if you’re going to attack someone, next time, check your facts first. If I were you, I’d delete the message altogether. The SD40-2 is a different locomotive, different frame, different truck, different electronics, water level sight glass, extended cab roof, bolt-on-battery box cover. You can tell a SD40-2 from an SD40 because it’s bigger, it has a huge front porch. Some of them have a snoot. It has the dampening arm on the truck. It has the alternative holes for the classification lights.
But you know what? Difference like that might come on the same model. The SD40-2 is a different engine because EMD says it is. They introduced it as a new model that replaced the SD40 in 1972. And in this case, the manufacturer determines whether it’s a different model, and that’s all that matters in this arguement.
Is that Phase I, Phase II, or Phase III…[}:)]
As has been mentioned, that particular 16 cylinder 6 axle EMD locomotive was an SD40 (did I miss anything?). The first one was, and so was the last one. Everything else is modifications and enhancements. There are those who will argue that because a sight glass is on X door instead of Y door, it’s a different locomotive.
I actually don’t disagree with you, which is why I say the only real determining factor is what the manufacturer says, and in this case they say it’s a different locomotive.
Argue all you want, but I made your exact point already right above. Doesn’t change the fact that they builder’s plate says SD40-2 on an SD40-2 and says SD40 on an SD40. And nothing else matters.
To me, shes a 45 if’n theres 10 holes on each side of the V.

So are you all preparing to argue that a 50 or 60 foot boxcar is not a boxcar simply because it is not the ORIGINAL size of 40’ or so? Or that a Tri-level autorack is not an autorack becasue it doesnt have only 2 levels?
