New York tests Beta real-time train tracker on LIRR

New York Long Island Rail Road Company (LIRR) announced that it had launched a beta test of an online tool that allows customers to see the real-time position of trains on a map and information about train lengths and locations of any trouble spots affecting train service.
The map is refreshed with new data every three to five seconds and benefits from the enhanced accuracy of GPS data.
“This tool is designed to be the gold standard level of information and should remove any doubt about where upcoming trains are and how many cars they have, and to provide a visual sense of how fast the trains are traveling. The myLIRR tool is an important component of our efforts to improve customer communications as part of the LIRR Forward plan,” LIRR President Phil Eng said.
Accessing, the customers will see a list of LIRR stations; tapping on a station gives a list of upcoming trains, organized by scheduled arrival time for the eastbound and westbound directions. Tapping on any listed train pulls up a map that shows that train’s location within the LIRR systemwide map, which is overlaid on a geographically accurate map showing streets, parks, bodies of water, and more, all in a muted fashion that allows train service to be highlighted. As the train moves, the icon representing the train on the map moves as well.
To help customers be prepared if a train has fewer cars than normal, the tool also lists how long each train is. Zooming in on the train displays this information graphically, by showing an outline of the train, with each of the cars in the train appearing on the map.
Instances where ongoing track work is reducing the number of available tracks are shown on the map with a wrench icon, and unplanned events that can delay trains, such a switch or signal problem, broken rail, track condition or disabled train are shown with an exclamation point icon.
To enable the tool to function, the LIRR has installed GPS transponders on all trains, nearly 600 GPS units in total. The GPS data supplements information from the LIRR’s signal system to provide the tool with accurate real-time positions of trains. Areas in tunnels where GPS is unavailable use signal system data and station stops and intermediate waypoint beacons to identify train locations.
