Positive Train ControlThe impact of legislative changes SCORT Chris Heald September 22, 2009
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? • 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? • 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? • In general (with some exceptions): • Commuter or Intercity passenger rail routes • High volume, high risk (PIH & TIH) freight
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? • 2 main technologies: • GPS and radio based • Track based transponder and radio based
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 - 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 • Technology choice of other shared users • PTC Type Approval status • Suitability • Cost • Availability
How? • System-wide areas impacted: • Locomotives / Cab Cars • Wayside • Signals • Central Control • IT
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 PTC
Cost • $10bn to $17bn over next 20 years Back Office Wayside Vehicles
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 • Freight Railroads, Passenger Railroads, and Infrastructure owners need to work together • Identify lead for PTCIP – joint submissions illustrate better system coordination between stakeholders
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
