This is a "freelance design" 2-4-4-2 articulated Locomotive and not a replica of any particular locomotive.


The project started with three main parts.
1- a locomotive shell:






2- a drive chassis:






3- a tender shell:






This gives you an idea of how the boiler and chassis will fit together.






The boiler shell was missing the smoke box on the front so I made one up out of sheet brass.






The boiler shell has been cleaned up and the new smoke box is soldered onto the front.







I used a piece of brass tube and bent it to form the steam supply pipe on each side coming from the steam dome and curving down and forward to the steam chest on the rear chassis.










The two steam pipes are cut at an angle under the boiler to mate up with the sides of the steam chest.






Here you can see the fit of the steam pipes to the sides of the steam chest.










There was 3/8 gap under the cab between it and the chassis frame.
I formed a pan to fill in this space and the brake cylinders and linkage are attached to it on each side.






Here is how it looks mounted under the cab.






A steam pipe is added to the front chassis.






The two drive chassis's are connected by a flexible drive shaft.






The electric motor is connected to the transmission on the rear chassis with a small U-joint.






The sides for the coal bunker on the tender were made out of pot metal.
I removed them and cleaned up the tender body.






Then I made up some new sides for the coal bunker out of sheet brass.






The sides are soldered on top of the tender body and a plastic coal load is added.






The water hatch, lights and ladder are added to the back of the tender.






Here is the completed locomotive.

Wow, what an incredible effort. That's a remarkable piece, and all your own creation which makes it all the more interesting.

If you had to give it a livery, which railroad would you paint it in?

Thanks for the great build walk-through!

Thanks John.

I haven't given much thought yet as to what the name of my railroad is going to be.
All my locomotives are a mix of things that I've put together like this engine is.
I don't think that I have any engines that are actually a replica of a real locomotive.

Maybe I should just call it the " Hodgepodge Railroad " and make up my own logo.

I like it! "HPR" - could make a neat logo for that...
