I abandoned this 2 years ago. But someone recently asked for the rear section files and I sent them to him. When I saw what he did with them, it prompted me to get back to my U25B to U33B (RBMN 3304). Now I’m certain it’s a bad idea!

What did you use for the radiator screen?
Fine wire (.23mm) mesh (~1mm hole spacing) Stainless. Commonly known as 18 Mesh (18 wires per inch).
I really like seeing top quality models and done with perfection, being a modeler first and a train runner second I know how much work you have put into your model, great work.
Nice looking loco,Dan, and the GE logo is a perfect finish detail. Is it a whole shell or a side on kit like your SD70 ACe ?
Beautiful. Love the GE logo. That is over the top cool and printed well.
Thanks Pete! The 3d printed parts replace sections of the model that must be removed or cut away. This shot may give you a better idea. Parts indicated with red arrows are original shell. I fixed the link. Printables
Thanks Devon! I use it as an example of why you really don’t need better than 2k for G scale prints. No Bachmann, USAT, AML or Aristo have any part finer than that.
Not really seeing the problem with the U-boat project, I already like it a thousand times better than the factory built U-25B! You absolutely must finish it. I’ve actually heard about this locomotive from other modelers before joining this site! Ironic I would get to hear from its creator . Also Those GE speed recorders and add on parts are outstanding! I have always wanted to learn how to use a 3D printer, but have no idea what kind of equipment or programming to use. I’m going to convince one of friends to print out the Alaska railroad parts out for me, but I eventually need to learn how to do it on my own. I’m amazed at how crisp and clean the detail quality is.
It’s pretty far along but it just doesn’t look right. A friend mentioned the cab seems too tall and after comparing to prototype photos we determined the cab is in fact tall and the windows are not positioned correctly.
I would cut the base of the cab to lower the roofline to the long hood hight, 3D print just the entire front section of the cab with the windows and door where you Want it, cut out old cab face, replace with 3D printed version. paint, and pull some freight! That really is a beautiful locomotive ! Aristocraft U25 cabs have always looked awkward to me. I could never quite figure out what it was about them, but they just need help for some reason. Here’s a face lift I did on an aristo U boat cab I encountered during the rehab of a kit bashed B39-8 someone had built . I wound up acquiring the unit and decided to completely rebuild it.
needs a lot of bondo, sanding and general overall TLC.
Also have this if it helps with ideas it’s the cab for my C30-7. I didn’t have a good reference, so I broke out the calipers and up scaled an ho scale Atlas cab part by part.
Nice work! I may just do that! There is a preserved U25B at a museum nearby and I keep thinking of getting over there to get some reference pics/measurements. They also have a U23B, B23-7 and B39-8E.

What is running on the Fore River Railroad?
I think they still run a pair of B23-7’s.
