Three Rail Locomotive Builders?

Not the quality of Brother's cabeese, but I did an 0-6-0 in 3-rail for OGR in the 1990s. I would post a photo, but my old technique no longer works here.

There was a guy in Philadelphia who cut up Lionel and made steamers of different configurations.  Bob Gale?

There is no difference in method between 2-rail and 3, as far as building is concerned.  I suppose the real reason nobody scratch builds locomotives in 3-rail is that 3-railers are more operation oriented. Two-railers are often hung up in copying the real thing.

There is lots of stuff out there that can be modified into most anything that you might like to have.

Yep. I can't stop myself. This started out as a Williams brass USRA 2-8-2; it is not that any more. It is not up to Brother Love;s standards, but I don't care. It looks good coming around the corner, and it is essentially accurate. I also try to build things robustly. I've done several steamers for myself. 

It is now a reasonably accurate GM&O Baldwin Heavy 2-10-0. I guarantee you that I've got the only 3RO (ignore the 2-rail track) version on the planet:

One of the real ones:

Point is: choose a project (a simple, cheap, easy one), plan your project (I do it in my head first, sometimes for months), do you research, grab your Moto-Tool and such, grab your courage, and start cutting or filing or attaching or removing...what's the worse that could happen? (See "cheap" comment above.)  

I like that GM&O Decapod.....with the coffin feedwater heater, like some of the Denver and Salt Lake Mikados.  I think you are right, that not too many duplicates of that model will be found, probably not even in HO.   The GM&O used to run a gas electric with an observation platform on the rear down through Illinois.  I would have liked to have ridden that.   One of the magazines, maybe "Trains"? did an article on that run once.

Very cool, good job. I am not familiar with the Williams, how did you add the extra axle?

D500, that looks AWESOME!!! Great job! 

D500 offers excellent advice.  Don't be scared.

Don't let bob2 be so modest, he builds beautiful steamers.  Hope to some day be of his caliber.  And, I agree with him, 3R guys seem to be about the gadgets where 2R guys love the details and not so much the newest 'rave'-Opinion.

You don't need a machine shop to do this stuff.  Those fancy tools make it easier, but it can still be done.  Some simple tools and accurate measuring will take you a long way.

Here's a Weaver FEF model I've been working on, need to get back out to the shop now that Christmas is over.  All the bare brass is stuff I've made or PSC parts soldered together.  Lots of fun in building your own!

D, you are too modest. You did a great job. I too m curious on how you added the 5th axle.
