RealTrax Oval Doesn't Lay Flat

That can't be correct.

Did you check all 12 of the curves to make sure they are  O-42?

I've never noticed that issue Mark and I'm kind of surprised because one would think it something that would be more prevalent here in Florida than up in your neck of the woods. What should we call that; a reverse super elevation?

It looks like you're using the older solid rail track? I wonder if you could reverse what ever is causing it by shimming the outside and weighing down the inside or temporarily screwing the oval down on plywood with the outside shimmed and letting it bake in the sun for a short time?

My regards buddy it's got to be a bit aggravating to have complications laying down a simple test track

Yes they are, that was my first thought too.  I have a circle of O-31, so I thought I had gotten one mixed in.  Not so.  I bought them all at the same time, so they should have been from the same lot, but that shouldn't matter.  Thank you for your suggestion.

Matthew,

Your thoughts make good sense.  I am going to inspect the track further to see if I can come up with anything that may be causing it.  I like the idea of baking in the sun, although I may have to wait until June for that here in Western Pennsylvania.  It is thunder storming right now, and I just realized I forgot to take the track inside last night. Oops.  I may be adding to my woes. 

Thank you.

I've had track that does that and sometimes it is caused by track bind.  You probably already did so, but make sure the straights are indeed true.  Also, try swapping curves from the other end to see if the problem duplicates itself.  I have seen some track that outwardly LOOKS correct but when compared to known good track, it's a little off.  

It looks as if the straight areas are not the same. Check those with a tape measure. A piece or area too long makes sectional track do that. What Volphin said.

Yes, I can see that what both of you are saying would be true.  I will inspect when I get home.  If it is true, then MTHs uniformity of like parts in like orders leaves a bit to be desired.

I have had a lot of RealTrak do this, if you take the track apart and view were the rails end you will typically notice that the rail to the left extends  beyond the plastic base and this causes the track to bind. I take a cut off wheel in a Dremel tool and grind the end of the rail flush with the plastic base, this will allow the track to lay down.

This is something I did notice that rail ends were touching.  From my long time experience with HO track, I know we wanted to have a bit of a gap between rail ends for seasonal changes in the rail's length.  If you butted them against each other, then the rail expanded, it could actually drive the track slightly out of gauge.  More of a concern with smaller, lighter, trains.  Thank you.

Scott, I checked and the rails are touching the whole way around.  I would say I am seeing the same thing you reported to me.  I didn't have time to do anything about it tonight, but I will have to get my Dremel back off my artist daughter who borrowed it for a 3D art project.

Thank you everyone who replied.
