Atlas's flex track section on their website picture is somewhat deceptive, as it says "Custom Flex Track - Wood Ties". But if you click on the picture, the individual item description that pops up clarifies it somewhat, as it then says "with simulated wood ties".
On the GarGraves website, I don't see any flex track with plastic ties. But I do see rigid track with plastic ties, available in 37" long lengths amongst others. Flex track with wood ties is also sold in 37" long lengths.
Either you ordered the wrong product, or else the dealer accidentally sent you the wrong item. You may want to check it out and see what happened.
