GECX ES44AC 2023

Well, it is a good idea in concept, but I am not sure how I could cover my butt if anything ever went sideways. My company has licenses to display most of these logos and even some have to be checked by the owners to be sure they are being used properly. This is something we take very seriously and is one reason why I am using official logos only from the owners or recreating their marks to the best of my ability. This is not only good for us since it maintains good relations with the owners, but it is also good for the customer to get the best and most accurate looking models. If I were to allow these to be used by others, possibly even misused, I would put relations at risk and some other factors that I wouldn't want to associate with.

That is just the bad side. If there is a way to do it and keep everyone happy I'd be glad to contribute.

Sorry to semi-bump an older thread, but can ANYBODY give me the scoop on what the TOP of the radiator looks like? Do the fans blow up and are directed left & right across the grills there or what? I have searched and searched for a picture that would be self-explanatory, to no avail. Is there a drawing somewhere that would show how it looks inside??

BTW, I'm talking about Tier 4.


Thanks in advance,

Dave Snow

If you note with the current ES44's, there are 2 fans on the top of that section. That has not changed with the new model, as they are present. I do notice that it appears the radiator section is actually larger than the current ES44's in action, but I do not believe the typical GE wings carry fans on the angled sections. However, it would be an interesting idea for such a thing though. Very good point, perhaps you should strike GE up with that idea and patent it as your own idea, make lots of money on it, because that could solve some serious problems. :)
 
yep they are starting to crank them out at the plant too, two waiting for pickup by CSX in idle

Looks like they are all still demonstrators however on test runs for the RR's. Wouldn't be surprised if those two go to BNSF.
From what I have heard, (This only hearing, it may not be true) is that the current Tier 4 GEVO's won't be ready until sometime late this year or the early 2016 time-frame. EMD is completely pulling out of the US market because they don't even have a model to lease demonstrators for and that is a true fact at this time. There is also talks that rebuilds like SD30ECO and GP20ECO's, SD40E's, and SD40N's as well SD40-3's may become outlawed so that railroads have to completely invest in a NEW fleet rather than taking the old ones back and making them better (Sounds stupid to me). This means that RR's are going straight up, and pulling out some really old stuff and using it while telling the EPA to kiss their red rosy cheeks. Since anything built before built before Tier 2 or 3 standards is not bound by the laws, their going to wear them out.
 
Since no one seems to be able to answer my question, I have another... Do Locomotive radiator fans blow up and out or suck in air?

`
 
I think it is just like on a car or diesel generator, a fan blows fresh air in, across the radiator ... the heat flows upward, under its own power
 
Top fans blow air out on most locomotives. Air is drawn in on the sides since cooler air tends to sink.

The fans actually expel heat from the block while circulating cooler air into it. I'm not super sure how it works on GE's, but on EMD's, they're pretty effective with the wings that help to expel heat as well. I know this from experience, as if you happen to catch an SD70M flared unit or SD70ACe at full power, you can actually feel the heat being expelled out the side vents.

well, both... :)

on your typical EMD the air comes in from the side, moves through the angled radiator and blows out of the top through the fans. there is normally a sequence of operations involving shutters on the side and what fans turn on (this is modeled on JR locos fwiw). on designs like the tunnel motor the air enters the side near the deck, blows through the fans and then into the radiator core and out the top.
GE locomotives usually have one large fan that pulls air in the side and blows it through the cores to the top but these pictured have two (they also have smaller intercooler fans but those are not part of the radiator system but the intake system). exceptions to the typical GE configuration being something like the P42 where the fan is over the cores.

on these units pictured the engine radiator is the rear most section of the 'wing' and the coolers are the front.

I can't figure out where the blown air goes. The top of the wings look like they are solid metal with grates on top of those. Is there a long open vent on the very top where the air is blown out?

Thanks very much all of you for the answers. I'm just not understanding where the fans blow the air out.
 
it isnt solid. the air blows straight out through the radiator. these are no different than your average automobile radiator in principal. do a google image search for radiator core that is pretty much what is up there just below the grates.
 
Also note, we are leaving out a vital fact. Most diesel-electric locomotives are liquid cooled, otherwise we would have some not so fun issues out here in the deserts where trains operate in temps that sometimes exceed 120 degrees in the summer. If I recall that the first VW bugs were fully air cooled and unfortunately for the deserts, this didn't work well.....

im not sure what that has to do with anything. care to shed some light on your thought process?

Yea, since he wanted to know a bit more about cooling systems of locomotives, I thought I would make it known that they're liquid cooled, because air sometimes is simply not enough :)
