Did you know the subway has been running in New York City since October 27th, 1904?
Obviously, none of the subway cars that transported New Yorkers in the 1900s still run today. But the cars that transported New Yorkers in the 1980s? Well, those might still be running.
And they might have broken air conditioners. (Which would definitely suck for you right about now.)
Everyone knows sweating while waiting for the subway is the worst during the summer, and the moment you walk onto the subway and get washed over by cold air is the absolute best.
So, how can you never, ever (we mean ever) get stuck on a train without an air conditioner again?
Well now, thanks to WNYC, the guesswork is over.
With their new Subway Field Guide, you can identify how old your subway car is, where it was built, and how long it's been in service. This nifty, interactive service will also let you know how many of these types of cars were in service in 2014.
So if your train is, say, thirty years old, you might want to wait for the next one. Just to be safe.
Here's how it works: slick the "start here" button and answer a series of questions about the car you're riding. Is the number sign at the top or in the side window? Is the train's front door sunken in, or flat against the car? Does the train have a stripe?
Answering these questions and you'll find out everything there is to know about your sometimes unreliable, sometimes way too hot subway car.
Right about now, you're probably super grateful about the subway's Wi-Fi because now you can check out all this information while you're waiting for your next train.
