  12. TWC Overview

  13. TWC IT Architecture

  14. RCU Architecture

  15. MITRAC Remote Architecture

  16. Ground Station Software Architecture

  17. Security Concerns • “Man in the middle” attack (eavesdropping); WEP cracking  Exposed data • “Drive-by hacking” • Falsified data • Rogue access points • Unauthorized access • Exploit remote server vulnerabilities • Gain access to NJT corporate network

  18. Security Solutions • Centrally managed, mutual authentication between mobile client and access point. • Server: RADIUS, LDAP • Authentication: EAP, LEAP • Improved WEP technology. • Per-session keys • Key expiration • Virtual private network (VPN) with encryption between mobile client and ground station on wired LAN. • VPN protocols: PPTP, L2TP, IPSec • Authentication: MS-CHAP v2, IKE • Encryption technologies: RC4, MPPE, AES • Firewall between access point and wired LAN.

  19. Cisco Aironet 350 EAP Authentication

  20. Authentication Summary

  21. NJT Implementation

  22. Standard Platforms, SW and Communication Systems allow focussing on core business applications Efficient team-based commissioning and troubleshooting of vehicles Time-efficient handling of maintenance and repairs Open for emerging e-business opportunities making use of vehicle-to-wayside communication 24h service and assistance becomes reality 24h MITRAC® RemoteSystem Key Benefits Courtesy: BOMBARDIER Transportation

  32. 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

  33. 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

  34. 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

  35. 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
