These are the people that make sure you get to work, safe and relatively on time. It was difficult to snap their portraits, as you may imagine, but I set up a stake-out around the Grand Central and Times Square stops this morning to bring you these photos of subway train conductors. Stand clear of the closing doors. Check back every Friday for a new photo essay.
See the photos in the gallery above.
