One of the things I truly love about New York is the subway system. Yes, I know it’s busy, crowded, occasionally stinky (I just left 59th Street and some people I know call that the stinkiest station ever.)
But what I love about the MTA is not their budget guffaws but the fact that when they developed the system over 100 years ago, they realized that Manhattan alone is about 8 miles long…and with that they did not want to stick passengers with an 8 mile ride where they’d have to stop at every stop.
So, they conceived of the 4-track system.
This system allows for two trains to head in the same direction. 100 years later, NYC is still the only place that uses this sort of technology. The only downside is that I have less time to write when I ride the express.
