Atlas O track height to top of rail?

2 or 3 rail, metric or imperial

If you're talking standard Atlas 3-rail track, I measure 12.1mm from the bench to the top of the rail.

According to Google it's 1/2" high

Edit: I see John beat me to it,  I'd go with his more exact measurement since 1/2' is probably rounded up and converts to 12.7mm.

Thank all you guys very much!

Steve, my piece that I measured wasn't brand new, maybe the rails are worn down a bit.

With that much wear, it may be time to call in MOW for a rail safety check.
