What Can NJT Do With This Data? • Better Labor Utilization • Better Planning - Short and Long Term • Better Troubleshooting • Efficiency Improvements • More objective data analysis • Better Train Location Information Do More With Less Maximize Available Resources
Labor Utilization • Data Gathering: • Ridership surveys • HVAC surveys • Car & Train Location - System and Yards • Advance diagnostic information • Updates to Information Sign Databases • Remote Troubleshooting • Train Crew - DTN • Wayside Based Tech’s - RDS
Planning • Ridership Information from PLD: • Identify small changes in Ridership Trends • Size Train Correctly • Allow Crew to Appropriately Zone the Train • Introduction of Database Analyst Function
Troubleshooting • Real-time View of What is Happening on the Equipment • From the Wayside • From the Internet • Download or View of Health Status of Vehicle Subsystems
