Hey, thanks everyone for contributing links and photos, great stuff!

I suppose you guys are bummed that MTH is shutting down? I have a couple of their steamers that can be switched over to 2-rail...which I always thought was a neat engineering feat...though never used it myself.

I enjoy all scales of model RR'ing, and am probably a 3-railer like 90% of all 3-railers, we grew up with it and it works in relatively smaller spaces. But, if everything was equal, I'd switch over to 2-rail O-scale..how can you pass up realistic looking track!

Footage of my railroad can be found in Terry Terrance's 2 hour  O scale promotional video.  Video coverage includes several very nice layouts including Chris Smith's and  and John Sethian's.  Here is the link to the video:  Terry Terrance's 2016 O scale video

The coverage of my railroad starts around 1 hour 11 minutes into the footage.  Someday we'll need to do a new video as there has been a fair amount of scenery and rolling stock progress since Terry videoed the layout.  However that won't happen for awhile as my next objective is to signal the railroad using the  NMRA Layout Command Control (LCC) bus standards.

Ed,

I looked at the Terry's video of your layout again.  It is spectacular.  I remember seeing the Model Railroader article of your Washington DC area layout.  It was one of the things that inspired me to go to O gauge from HO.  However, I am 3-rail because I don't have the space for O scale curves.  I would enjoying seeing your layout if I ever get to the East coast again.  NH Joe

Hi Paul,

There are some who use Proto 48. Photo 48 is proper 4'-8.5" scaled down spacing between the rails while regular 0 scale 2 rail and 3 rail uses 5' spacing between the rails. The difference is a little over 1/16". The equipment for Proto 48 won't work on 5' gauge track, and the equipment for 5' gauge won't work on Proto 48 track.

Another thing that might make a difference in appearance is that some people use code .148 heavier mainline rail and others might use code .138 and others might use code .125. I chose mine based on what the prototype used. Most 3 rail track uses taller and wider rails than what is generally offered in 2 rail. I think I've heard it mentioned that Atlas 3 rail track is code .225 compared to their 2 rail track offerings which are code .148. Code .225 would be off the charts heavy rail.

Also, unfortunately my friend Joe Ioele won't be joining the discussion about his completed railroad. He is also looking to get his railroad published.

Great videos.

Question on the track: it appears that in some of the videos the 2-rail track is narrower and in others wider, yet none were narrow gauge from what I could tell. Are there actually different gauges of 2-rail O-scale track?

Besides P48, there's also On3 (3'), On30 (30"), On2 (2'), and On18 (18").  There's also PA Broad gauge for the trolley modelers, although I've yet to see anyone actually model using that variant.

Paul,

The code of the rail is measuring the height of the rail as Phil and Martin confirm, but at least in the case of Atlas and probably others, I think the width of the Atlas Code .225 track rail head is wider than Atlas Code .148 track rail head. It has been a while since I did some comparisons of track to determine if I'd stay in 3 rail or switch to 2 rail. At that time the center rail did not bother me but the rail in the Atlas 3 rail track seemed considerably oversized in every dimension, at least for the era I chose to model.
