Can anyone tell me the word for this kind of train track?

At the center of the picture is a piece of machinery called a turntable. A turntable is used to turn locomotives end-for-end so they will be pointing the right direction for a mainline run, and also to provide access to a compact storage and maintenance building called a "roundhouse," which has a series of stalls surrounding the turntable, each with a track that can be accessed by positioning the turntable to align with the stall.

For much more information, including lots of pictures and diagrams, run an internet search on "railroad turntable."

Note: "Train track" is a juvenile sounding expression. If you want to sound like you have some knowledge of railroads, say "railroad track," or just "track." It's no big deal, but it makes a difference in how you come across.

Good luck!
