This nearly half hour piece on the subway system in the 1990s starts out with Ellis Henican (then a Newsday columnist) painting the picture of an underground lair filled with mysterious things—he's like M. Night Shyamalan seeking out a shocking twist in the transit system.
He talks of ghost stations and subway bathrooms—both dubbed equally "creepy"—before introducing viewers to the mysterious ejector room, which he says "sends shivers down [his] spine." Alas, he give no answers as to what goes on in there, despite being curious himself. We're just left to assume it's something to do with murder or portals to Hades.
He also says that late at night isn't the most dangerous time to ride the rails—"You know what's the most dangerous time to be on the subway? There's more crime, and I'm talking about violent, serious crime, between 2 and 4 in the afternoon than at any other time. That's just when the kids are getting out of school. There are more subway criminals than ever before, and they're getting younger and younger every year."
Stick through it to the end, where you'll meet the best subway conductor ever.
