O-27 profile track, but O-31 diameter

Could be Marx track.

I do not know the answer about 027 height, 031 diameter, but, in the years of 2000 to 2003 I purchased 150 pieces of 027 height 072 diameter to build two Helixes, and the track was made by K-Line....So, my thoughts would be K-Line. 

The 027 stands 7/16" high and the 0 stands 11/16" high, and the 031 radius typically came from K-line.

If it has five crossties on each piece of track, it is probably Marx "wide radius" with a 34" diameter curve.

I just came across 16 pieces of tubular track that have an O-27 low profile but are longer than traditional O-27 track and with an O-31 diameter.  Was this made by Lionel?  If not, who made it?  There are no markings.  There is a lockon attached to one of the curves, but there are no markings on it, either.  Any info would be appreciated.  Thank you.

Photos would help in trying to identify it.

Here is a picture of Marx O34 Vs an MPC O27 track. Hope this helps, if this isn't what you have, a picture would be most useful.

Side note: If you (or anyone else for that matter) are looking to get rid of it, I'm always looking for more of it! :-)

The Marx O34 is 31.5" center rail to center rail and 34" outside tie to outside tie edge. it makes a 34" circle. That was how it was marketed. Don't forget these get wiggly and out of shape over time. The clue is the five ties. It should be close to 12.5" long from outside rail end to outside rail end.

It was designed to work with the O27 curves. You may find a circle M stamped in the ties, but not typical.

It's a good size track for a small table.

Yes, what I have is Marx track.  I never knew they made a wider radius curve and a longer straight track.  But, I did know that putting a post on this forum, I would have an answer.  That is what I like about the OGR forum.

Thank you to all who took the time to answer and provide information.

Marx O-34 carries some value, too.  I had a box that made a decent size oval (~10'x3') that I sold on the Bay for $70.  I did include a Lionel O27 switch for a single siding, but those only have about a $15 value at best.
