The biggest difference is that 2-rail O scale is DC, so it does not have a need for that "unrealistic" middle rail... Some newer locomotives, with MTH at least, can be converted from 3-rail AC to 2-rail DC and vice-versa...

The other major differences are the wheels and couplers... Even with true 1:48 3-rail O scale rolling stock, the trucks are still out of proportion as the flanges and couplers are way oversized... Instead, with 2-rail O scale the couplers look prototypical, like an HO scale truck for example...

B&M,

Re: your comments / descriptions of 2 vs. 3 rail rolling stock ...

Ohhh ... very interesting ... I'm gettin' it now. Huge difference in the proportions of the couplers, as you show.

Just out of curiosity, any guess as to the percentage of O-guys who are running 2-rail DC (as opposed to conventional 3-rail AC)?

I didn't even know that rolling stock like that in O existed.

Thanks for clueing me / others in!

now that looks like a model railroad. no offense to old school 'O' scalers but to me that 3rd rail looks just like 5th wheel on a car - kills the entire deal.

B&M, how feasable would you say O scale for garden railroad? do they have line of products that withstand the elements?

I have no clue, but it has been gaining popularity... It is not like 3-rail O will ever die though...

Meh, I still like it, but I am not too much into the whole modeling thing...

I personally have never seen any O products that stated they were okay for a garden railway, but it has been done: http://www.modeltrainforum.com/showt...hlight=outdoor

I saw some really neato Atlas 3 rail O gauge track that looks like 2 rail. If I had O, I'd use it in a heartbeat.

Choo Choo, that looks sharp! if I were considering an O gauge outfit, that would be the way to go.

Yes, there are multiple companies that make a blackened out center rail to hide it somewhat...

Clueless comment ...

A much more experienced O friend of mine cautioned that the blackened center rail can cause more unwanted gunk buildup on the pickup rollers, as compared to conventional track. Any concerns of note and/or truth to that?

Jeez... that sure shows what a newbie I am.

I had no idea that O trackage was so sophisticated...

...or so expensive!

Hey Reck,

I only have one O gauge Lionel Trolley...

...but might get a circle of that really cool Atlas track to run around the Christmas tree for about 100 bucks.

the third rail is only subtly camouflaged. and even then after proper ballast and weathering i can not see this being made to look prototypical. unless geared railraod is modeled ...
