“New York Subway” (1905) IMDb
Seen in 2017.
The double-track action is pretty nice. I watched this together with a 2015 CBS report on the progress of the Second Avenue line, shot via drone. Fewer bowler hats, better footage. In the CBS piece, reporter Don Dahler asks project manager Michael Horodniceanu: “Do you ever think about the fact that what you’re building here is going to serve people for maybe over a hundred years?”
