Building the EMD Model 40B Center Cab Engine in 7.5" gauge

- I designed and fabricated this engine, in efforts to own one that would pull up to 10 passengers while not be too large. During research I came up with several design options and decided to stick with a four wheeled design to keep it simple. This helped in transporting and handling the engine. Since its completion, it has proven to be easy to maintain and extremely reliable.
Sold in 2012, it is missed.
I will be posting building compilations of each rail car that I designed and built for it to pull. Check out my K.J. plans caboose.
Direct any questions to David ( rcpilottoo@gmail.com )
08/05/2024 Visit. Very nice job. Great music too.
I like how you used the vinyl graphics for the various door outlines. Great looking (and bulletproof) engine.
Chris;
This Briggs & Stratton powered engine and entire six car train that I designed and built turned out to be one of the most reliable and low maintenance at most of the RR tracks that I ran it.
I made the door outlines and various other needed straight lines with striping tape available at most hobby shops and/or auto parts stores. It comes in many different widths and colors. Part of the scratch building "fun" is letting your imagination go wild. Plus, it doesn't cost much if we goof some up. I appreciate that you even noticed.
I am very lucky the have a son that works for a display company and made all the rest of the vinyl graphics for my entire train!. Some where white and some were black. And if you look close, I used both white and black shingled, to create a 3-D effect in a few areas.
If you or anyone has more questions, my email address is listed above. I also have about two-bizilion construction photos. Don't hesitate to send me an email and ask.
I'd like to show you some of the rolling stock that I built. An engineers car complete with a swivel seat and a twelve volt air compressor for the brakes, a steel gondola, a steel flat car, a wooden gondola that could be changed into a flat car with stakes or a Maintenance-of-Way car at a moments notice, a tanker and a true scale wooden caboose.
My C-30 caboose planes were purchased from Keith Jackman. My construction video was pulled off RUclips because of copyrighted background music. The background music in this video is, in my opinion "stupid", but free to use............ds
I was thinking about building my own 7.5 scale engine, and i want to ask what engine you used, as well as cluch and controller!
What metals did u use to construct the frame and cab body. Looks like aluminum but hard to tell
Chris;...The deck, front, sides and rear frame were all 3/4 inch mild steel. I used 3/4 inch to help add weight. For me to do again, I possibly might use 1 inch thick mild steel just to add more weight.
For the cab and the two hoods I designed and fabricated using 16 gauge mild steel sheet. Being about .062 (1/16th) thick made it easy to form, roll and bend yet strong enough especially for around the windows and hinged roof.
I would use 16 ga. mild steel again. FYI, I also used 16ga.ms for my five foot gondola, six foot flat car, the engineers car and the changeable combination stake/flat/gondola/maintenance-of-way car. It took me awhile to figure out what materials to use since I was new at designing and have never did this before.
Send me your email address and I will provide you with construction and finished pictures of these cars if you want.

I did scratch build my wooden C-30 caboose, however, the plans for the caboose were purchased from Keith Jackman www.discoverlivesteam.com/discoverforsale/forsale/1_jackman/index.htm
Hi David, What kind/type/model of hydraulic drive is that? I would absolutely love some more information! Thanks!
did u get a reply on the gear box on axle and the gear box on motor? I want to do the same thing to mine. Peter Email Pgrillo@atlanticbb.net
The gearbox on the axle is a 2 to 1 or 2 and 1/2 to 1 tool o matic I believe that's how it's spelled the hydrostatic transmission he is using is an Eaton 7 or 6 hydrostatically controlled transmission I hope this helps the both of you
do you happen to have a dimensioned drawing of the parts etc?
I drew scale sketches on 1/4" lined graph paper of all the parts before I did any fabricating. With little thought of ever needing to use these plans, they ended up scattered in different locations. My thoughts were, "now I have the finished product and I don't need the drawings any more". However, this simple design wouldn't be to difficult for someone to duplicate just using my available photos. After all, I'm just a "shoot-from-the-hip hammer mechanic" and I was able to succeed.
In the end, it turned out just as I wanted. Not too big (324 pounds), easy to load in my mini-van, yet able to pull up to 10 riders and extremely easy to operate.
Lisa, I'll take your question as a complement from someone who may have the same design needs that I did. I'd like to believe that it's new owner is enjoying my design also.
So come on, let's get going,,, you can do it. I'll be right here to answer any specific questions as they come up. Plus, I do have many "tell story" photos that I can send to you. Or, there is this RUclips video to refer to.
My e-mail address is on the RUclips engine build site.
I miss that train, especially the engine..........Dave S
Check the April 1962 issue of Model Railroader Magazine.
thank you very much for that info. took me a while to find one of those magazines, but sure enough, drawings, dimensions, etc.
WOOT!@@adirondackcarfoundry368
