Positive Train Control The impact of legislative changes SCORT Chris Heald September 22, 2009
3
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
4
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
5
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
6
Where is PTC needed? In general (with some exceptions): –Commuter or Intercity passenger rail routes –High volume, high risk (PIH & TIH) freight
7
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)
8
How it works
9
How - Technology? 2 main technologies: –GPS and radio based –Track based transponder and radio based
10
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
11
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
12
How - Technology Selection Factors Technology choice of other shared users PTC Type Approval status Suitability Cost Availability
13
How? System-wide areas impacted: –Locomotives / Cab Cars –Wayside –Signals –Central Control –IT
14
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
15
Cost $10bn to $17bn over next 20 years Wayside Back Office Vehicles
16
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
17
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
18
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

Thank you PARTNERING TO ACHIEVE THE VISION P C T P T C
