Hello -

I'm going to be starting the construction of my 4' x 8" layout soon. I need to have my curves at a minimum of O36 to accomodate many of my locomotives and some of my rolling stock, and at a maximum O36 for space constraints.

Recently, I bought a pair of new-in-box Lionel 6-14062/3 switches. The boxes state that they're both O22 with a 31" path. What does that mean? Are they reliable and long-lasting, or is there something better? I believe original Lionel or K-Line track was never made in these configurations to accomodate the switches I have. Or did they? If not, I think my best option is to use tubular track from Menards in O36. I really like the traditional look of this type of track, but researching this forum and other sources, the Menards track gets mixed reviews.

Is this switch O27 profile track only? I know the Menards track is taller. Since they're different, how can the two be seamlessly combined? Would you recommend this, or not? I searched the forum for answers to these questions that may have been discussed earlier, but I didn't find what I was looking for. If you more experienced modelers can chime in on this, I'd be grateful. I'm new to the hobby and want to avoid making mistakes or buying the wrong stuff. Please forgive me if I've used some of the wrong nomenclature in describing my inquiry. Thanks for any guidance you can provide.

The switches are O gauge tubular track.  Not compatible with O27, and are a nominal 31" diameter curve - they match traditional O gauge track.  Should be compatible with Menards O gauge tubular track (I've seen Menards track but do not own any).  If you really need 36" diameter to accommodate your equipment, they are too sharp of a curvature.  O22 is a reference to the postwar model number for similar switches.

The boxes state that they're both O22 with a 31" path. What does that mean?

Well, it means that they mimic the original Lionel O switches(022, eg.) in that they have a 10" straight section, with a 1/8 of a full circle turn out. That full circle(and hence that piece of curve too) is 14.14" center rail radius. The "31" designation comes from the approximate measurement of original Lionel "O" track diameter as measured over the ties...

I believe that the Menards O36 curves are 18" center rail radius.

Both are traditional "O" profile, not the more realistically proportioned O-27.

OK, now I understand it better. But will the only curve off this switch need to only be O31, or can I use anything else? What would you guys recommend as far as track? One of my local club members said that most trains rated for O36 will navigate O31 if run slowly. With such a small layout, I didn't think I'd be running my trains fast anyway. I always appreciate how much knowledge is to easily be found here by simply asking a question.

4x8 is just barely enough for an O-gauge layout.  If I were going to build a layout that size, I would use Ross O31 curves and switches, and not O36.

You didn't say which locos you have, but I disagree with what your club member told you.  If it's rated for O36, it will probably balk and may derail on O31 curves and switches.  With prolonged operation on sharp curves, the flanges on some MTH steam 8-drivered steam locos will wear to a knife edge.  IMO you're asking for frustration.

Unless you can negotiate a little more space--at least 5x9 or so-- I would stick to trains that were designed and rated for O31.  My $.02.
