I don't recall the C station ever being closed. It has always been open when I have transited to and from the North Terminal, the last time about two weeks ago.

There are three trains in service:

• One runs back and forth between Main Terminal North and Main Terminal South.
• One runs in a loop between Main Terminal North, the North Satellite, and the C Concourse.
• One runs in a loop between Main Terminal South and the South Satellite.
