The MTA Metro-North Railroad and the Municipal Art Society of New York have teamed up to celebrate Grand Central Terminal's 100th anniversary by leading daily docent-led tours of the landmark transit hub. The tours, which run from 12 to 1:45 p.m. every day through Oct. 27, highlight the terminal's history, eye-catching architecture and day-to-day operations as one of the world's busiest rail centers.

Tickets cost $20 for members of the general public, and $15 for Municipal Art Society members, students, seniors, military service members, children 10 and younger, and Metro-North passengers bearing same-day ticket stubs.
