Name of something...

What's the name of the metal things in the underground that you put your tickets in and the gate opens. I hope you can tell what I mean from the poor description. Thanks in advance.

Them there are referred to as "turnstiles".

Glad to be of service.

Well not really glad, but at least I was of service.

''turnstiles''.....for some reason the name just escaped me.
