what is positive train control
What is Positive Train Control
  • PTC is a system that has been mandated in Federal law that is required to:
    • Reduce the risk of train to train collisions
    • Reduce the risk of overspeed derailments
    • Provide additional work zone protection
  • PTC is infrastructure / locomotive / office based system
  • Enables a train to know it’s movement authority and take action to remain within it
why ptc why now
Why PTC, Why Now?
  • Current position:
    • Safe transportation of freight and passengers
    • Occasional accidents
    • Human error remains one of the most significant factors
  • PTC provides oversight of human actions to reduce risk
  • Technology is available
  • Cost benefit will never be positive on safety alone
when is ptc needed
When is PTC needed?
  • RSIA 2008 requires:
    • PTC in place by December 31, 2015
    • PTC Implementation Plan (PTCIP) submitted to FRA by April 16, 2010
where is ptc needed
Where is PTC needed?
  • In general (with some exceptions):
    • Commuter or Intercity passenger rail routes
    • High volume, high risk (PIH & TIH) freight
how it works
How it works
  • Train is intelligent…
    • Movement authority – advised by wayside
    • Speed – Tachometer, GPS
    • Track topography – on board database
    • Cab Location - GPS or Transponder
    • Train length – manual input
    • Direction – GPS or Transponder
    • Civil and temporary speed limits – database and manual data update via radio
    • Braking capability – braking algorithm (verified through testing), train consist (manual), train weight (manual)
how technology
How - Technology?
  • 2 main technologies:
    • GPS and radio based
    • Track based transponder and radio based
how technology10
How - Technology?
  • GPS and radio based
    • V/ETMS, ITCS
      • GPS location within 10 feet
      • Could be effected by mountains, buildings, tunnels.
      • Data rate limit may mean train speed <125mph
  • Class 1’s working on Wabtec V/ETMS solution with interoperability
how technology11
How - Technology?
  • Track based transponder and radio based
    • ACSES
      • Location verification by transponder with tachometer based intermediate positioning
      • Suitable for use for high speeds
      • Suitable for use in tunnels
      • Transponders – installation and maintenance intensive
  • North East Corridor (Amtrak Acela + NJT / SEPTA / MBTA / MNR / LIRR) will remain ACSES
how technology selection factors
How - Technology Selection Factors
  • Technology choice of other shared users
  • PTC Type Approval status
  • Suitability
  • Cost
  • Availability
slide13
How?
  • System-wide areas impacted:
    • Locomotives / Cab Cars
    • Wayside
    • Signals
    • Central Control
    • IT
implications for the states
Implications for the States

Inputs:

  • Project Funding – tax mechanisms, investment deferment, loans
  • Project Resources

Outputs:

  • Improved safety
  • Improved infrastructure use
  • Improved energy use
  • Opportunities for future rail services

Cost
  • $10bn to $17bn over next 20 years

benefit
Benefit
  • FRA identify $1Bn in safety benefits
  • Business benefits intentionally not identified
    • Fuel savings from train pacing
    • Cost and Emission reduction
  • Reduced Risk
    • …reduced liability exposure
way forward
Way Forward
  • Freight Railroads, Passenger Railroads, and Infrastructure owners need to work together
  • Identify lead for PTCIP – joint submissions illustrate better system coordination between stakeholders
conclusions
Conclusions
  • April 16, 2010 is less than 7 months away
  • All passenger railroads need an implementation plan
  • PTC is a wayside, office, and vehicle system
  • Take action now
