This was posted to another forum I belong to, and I wanted to share it with you all here. https://radar.mta.info/ The New York MTA has a map with live train information for both Metro-North and Long Island Railroad. It has train numbers, running times, etc. It's pretty neat to watch and see what's going on in the system.
I love it! I use it to see what consists / trains are being used when playing the LIRR 2.0 route. It’s AMAZING when railfanning. Can see who and what’s coming.
