Are the rails oval or round in shape?

Oval. Flat on top with a rubber strip. Easy to place and remove. Has a lock and key to secure.

They are oval in cross-section. And they are specific to a front and rear one (the front one has little spoilers underneath). It has a neat locking system that prevents the racks from being stolen. I can pop mine on and off really quickly now that I have done it several times

They are round. Be advised that they break and scratch extremely easily. Quick changes in temperature is enough to break them.

According to Yakima, they will work with round, square and oval bars. I am using them with round and see no reason why they would not work with others.

They are not round; they are flat from the top & almost "boat-shaped like" on the bottom so that would make them somewhat oblong. Hope that helps.

They are neither round nor square. The cross section is more like an L with the 2 parts of the L having equal 1-1/8 inch length from the angle between them. Plus there is a cylinder tucked into the angle between the 2 that the screw goes thru. This cylinder is part of the footprint of each foot.

This is a great product for squared off rails, I have to agree with the other answers that it would be unstable on a round rail without modification. Too bad.

Some are, some are not. The curved tracks and junction tracks are, the straight tracks are not. Hope this helps. My daughter LOVES these tracks and they work very nicely with the Thomas trains. A year later and she still plays with these nearly daily.

They are indeed rounded. I think it gives them a good look. I am happy with their appearance.

They are round! But wouldn't recommend them. I bought these in January and 4 months later I only have 3 left. They crack real easily

They are square, with a pointed end. You can't go wrong with these. Our grandkids ages 8 to 13 love them.

It's straight, not L shaped. I assume that's what you meant by round or square.

No, its rounded. The photos LOOK like it is flat but its not. About 70% of mine contacts the dashboard.

The matching end tables are round not oval. They look nice together and great with my sofa.

no they are small round metal bars. I love mine and it was very easy to put up, even for me :-)

Not sure. We lost interest in the monotonous train set and packed it away somewhere in the garage. My best guess is it probably takes 4 curve pieces to make a half circle.

Mine is oval with no flat side, really. They work great! So glad I got them, sick of the ladder!

The plates are round, but all the pieces (except the cups) have a slightly irregular shape. The bowls are in fact somewhat oval shaped rather than perfectly round. I happen to like the irregularity, while my husband calls them "misshapen".
