GE Evo air (brake) tank part?

Ah well. I'll just make a piece that looks like it does.

Joe, if I had to guess I say it's probably an air filter or air dryer.  I need a better picture to really get a sense of what the part looks like.  You might compare it to parts in the Details West HO catalog.  They have several air system parts for GE locos that might match what you are looking for.  Their catalog illustrations are not very good, but you might be able to buy the part and use it for a reference.

Joe, I looked through all my GEVO stuff and could not find real good close- up pic of that area. From what I could see is that may be a cover to protect valves to release any water in the main reservoir tanks. Hope this helps. Great job on the air tanks.    

Ok, I've had a chance to look at some better photos.  I think what you see there are a series of parts, rather than just one big part.

I'd say the "gas pedal" thing is a sheet metal shield covering something else.  That could probably be done with styrene or brass sheet.

There is a moisture drainage valve at the bottom of the end of each tank, it's why the tanks are angled down to that end.  That part is available from PSC, #56146.  It looks essentially the same as the one you would see on an EMD tank.  This is one of my photos from an sd40-2, but the GE looks the same to me.

Also, if you follow this link to the Fallen Flags site, you'll find info (for EMD) on the drainage valve.

The rest is really just piping for the air system, comprised of unions, elbows, and tees, plus the flange where the pipe enters the end of the tank.  You can get standard plumbing fittings from PSC, or make your own by wrapping thin styrene around rod or tube to simulate the fittings.  The appliances like the filters and moisture traps happen elsewhere, at the ends of the fuel tanks.

I'll see tomorrow if I can get permission to pass along a good photo that should help with modeling this area.

WOW! Thank you all for the great help! I really couldn't find a better pic to know what I was seeing.

It all makes sense so I know what to capture overall.

Here's a page from Details West:

Here ya go, Joe.  I think you will find what you are looking for (and probably a whole lot more) at the following two links:

ES40DC

ES44AH

Here are some photos of the PSC part.  Not great shots, but the best I could manage on the fly with my phone.

WOW! Thank you again!

I couldn't seem to save them, so I saved them as target.

When you select a photo, it's as good as being right there!

Yeah, I think flickr disables the save as function, or maybe that's the case if you have a paid account.  Either way, the photos are there as a reference.  They are exactly the type we need for detailing.  Be careful, or you might get lost checking out the albums.  There are a lot of great photos in the albums, both train and non-train related.

Btw, I also passed along your build thread for the es44.  He's also interested in doing them in G, although he tends to work in etched nickel silver rather than styrene.
