With your permanently negative attitude, it is easy see that scanning a bunch of useless dots on a map make you more restless. Those dots mean nothing in real time as a train crew tries to "get it going", but you could not care less and find a way to bash them. Take a walk in the shoes of the hammered someday and learn the mental and physical punishment they endure.
Not sure what the response above is all about but this is a pretty cool resource. Similar to the sites that provide real-time flight trackers. Neat to see the positions of all of the trains in the Greater New York region in real time. Not sure why that is such a bad thing.
