    Finished up last night. Athearn GP 38-2 #671. Weathered with Pan Pastels and a bit of acrylic paint in spots. Added speed recorder, sunshades, beacon (nonworking), air lines, grabs. Was a fun little project.

    Thanks for looking!

    A work in progress, Athearn GP 35, I am adding roof tanks and piping. Next will be the fuel tank extensions. Then weathering to finish. I hope to have it ready for the clubs December Operations Session on the 8th of December.

    Thanks for looking,
    Dale

    Thank you Joe! And everyone for the Likes! I’m having a great time catching up now that colder weather is here!

    The GP 35 I’m working on now will have piping on the roof as well. There is piping that goes from the back end of the tanks and runs around the back end of the long good. I’ve been thinking about how to bend it. I’m pretty sure I’ve figured it out. I am going to use a block of MDF and draw out the shape of the hood on it. I will then layout the lines to represent where the air piping runs. I am going to put pins at the bend points and use that as a template for the wire.

    If it works like I hope, I’m going to start a cottage industry of air details for GP 35 locomotives. I ought to be able to sell a half dozen or so!!!!:ROFLMAO:

    Anyway, I’m having a great time with it and When I get done, I’ll have a nice set of locomotives I can MU and run at the club. AND, on one else will have one!

    Again, thank you all for looking in and the positive comments and thoughts!

    Check in the forums for GP35's. I recall a few years back I posted a plan view diagram I made of the roof air piping for the torpedo boat GP35's. It might be of help to you on your project.

    Hi Tom!

    I looked at it, it’s pretty plain I’ll be starting over, I made the tanks too short. I can lengthen them no problem. The double piping on the rear hood is going to be a challenge. But I’m going to at least get it to look right.

    Ken, I really appreciate you and Tom pointing me at the threads, especially since I’m not too far into building it. I had the fuel tank extensions figured out. I looked at as many pictures as I could find, and I thought they did not extend past the dynamic brake blisters. Apparently they do. The pictures of Tom’s build are great!

    Thanks,
    Dale

    ETA- Ken, I looked at your drawing, if the tanks are in close proximity to what you show, I may not be that far off the mark. I will just leave them as they are and go ahead with the piping and tank change. I figure since you took the time to note everything you did, you are pretty accurate on the whole thing. You show the cross pipe behind the stack which is where I have it. I can run the rear piping as per your diagram.

    Thank you all for pointing me in the right direction!

    Read the whole thread if you can. I pretty much explain how the whole process was done, wire sizes, wire bending on and on, plus with the input of many others, it was and is a very entertaining thread. All together I have built 6 of these modified Geep 35's. Usually a bit more work than some even want to consider on occasion.
    You dont need to shorten your tanks, necessarily, there are DA tanks available that are correct, but you will need to mount them correctly, again all explained in the whole thread, it is well worth the few minutes of reading. All the paint colors used, I also, did a RTR GP35 too, if you want to do it right there is a little more work involved.
    Thank You,
    Tom

    Hi Tom,

    When the master speaks, grasshopper better listen! I’ll give it a good read this evening and probably several times! I’m up for just about anything these days. This is going to be fun.

    Again, thank you guys for all your help!

    Hi Tom,

    I gave your threada read through last night and this morning, 5 pages of excellent information! I am going to start over on the tanks. You photos of the W/O Athearn are great. I will start looking for the parts.

    As far as paint, I can get close then weather it on out, from the photos I’ve seen of those unit, it looks like the roofs we’re almost burnt to a crisp.

    Thank you very much for pointing me in the right direction!

    Dale - Remember my GP35 top side drawing is without any accurate dimensions. It was sitting under a bridge in Rolla, and I was on the bridge looking down and sketched what I saw. Not a single measurement!

    Hi Ken,

    The thing that stood out to me was the placement of the front piping, it shows behind the stack in the drawing, where Tom’s are in front. Possible field modifications?

    Thanks,
    Dale

    Ha Dale, But im not the master around here LOL.
    If you go to page #1 of the thread I posted above, about 3/4 of the way down that 1rst page you will see a rooftop photo that clearly shows the crossover pipe in front of the exhaust stack and with the pipe going down into the carbody on the F/S.
    Hope this helps,

  15. Hey Dale for what little it is worth with all the good info here. These are a couple attempts I made years ago. Far less precise than Tom's. But passable if they roll by in a train with non Frisco guys watching.:D
    Funny this came up because I have a large scale one to start, I hope to have finished for the 2020 RPM in St Louis, this has been a good refresher course .Thanks

    Here is the Overland version I was fortunate enough to acquire. You can see they have the tube in front of the exhaust too. I'm positive they are way more precise than me so I would trust them.

    Yup, I did see that Tom. I’m redoing the whole thing. I ought to be a master at this by the time I finish! That’s also the one that looks like they built a fire on it!

    Thank you guys very much for all the pictures! I will get started on my redo this weekend. I really appreciate the shot showing how the back pipe goes into the hood at the back end of the loco. I will post up pictures as I go.

    Thanks,
    Dale

    Tom, Thank You for the photo of a GP-35 with the torpedoe tube piping. I downloaded it to my gallery for future reference.

    All I know is that I sketched what I saw on that particular GP35 unit sitting there in Rolla, under the overpass. I don't recall the unit number - I'm sure I have it somewhere. Note I did also sketch the support pillar under the piping going across the width of the hood ahead of the two tanks. I don't think I would have added that detail and then also got the orientation of the tank ends, cross pipe, and exhaust stack wrong. Who knows.

    But, for sure, there could have been differences in this detail between various GP35 units. EMD might not have done all of them the same, as it was non-standard GP35 feature, and/or the SLSF could have made a change as well after they received them or during a shopping. Happened all the time. Note also this unit had some insulation on the end piping down at the end of the hood, such that a crew member climbing the end ladders would not burn his hand terribly by accidentally grabbing on to the air pipe as he climbed up. I don't think EMD added that.

    Thank You, Steve, for posting the GP-35 torpedoe tube details.
    I downloaded the photos of your locomotives too. They will be useful details for the future projects, just need to find a couple of Frisco GP-35's for N scale.
