INFRASTRUCTURE French Highspeed on South East TGV line: 25 years of evolution Jean-Paul BALENSI Vice-president of Operation System and Safety Division SNCF EURAILSPEED 2005 Milano, 7-9 November 2005
Introduction First French HSL was open in 1981/1983 on Paris Lyon route. General lines scheme: 2
Building the first HSL: a bet for the National Railway Company SNCF A French strategic and economical choice in order to revitalize railway passenger traffic. Evolution of passenger traffic flows and modal market shares: TGV / AIR Market Shares between Paris and Lyon 100% 90% 80% 70% 60% 50% 40% 30% 20% 10% In m illions of p asseng ers 100 80 60 40 20 CHARTER THALYS EUROSTAR TGV NORD Interconnecting TGV TGV ATLANTIQUE TGV SUD-EST TGV traffic in 2002: 87.8 million pax 1980 1981 1982 1983 1984 1985 1986 1987 1988 1989 New Line Commissioning 1990 1991 1992 1993 1994 1995 1996 1997 1998 AIR TGV 0% 0 1981 1982 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 Years 3
Building the first HSL: a bet for the National Railway Company SNCF (2) A completely new technical environment and a major investment for SNCF: new dedicated infrastructure, new signalling system, new type of rolling stock. Investment costs: What is the traffic? A 90% increase in traffic ridership, 18.2 million passengers in 1991 24.3 million passengers in 2000 TGV Sud-Est How muchdoesitcost? Whopays for the investment? Infrastructure : 1.86 Rolling stock : 1.56 Total : 3.41 (billion Euros) SNCF own money and borrows Is it profitable? Profitability for: SNCF: 15% (IRT) whole community : 30% 4
How to ensure safety running at 300 km/h? Adapting infrastructure to highspeed: Enclosed line and no level crossing Wider distance between tracks Either-direction working tracks 5
How to ensure safety running at 300 km/h? (2) The cab-signal: a specific on-board system for highspeed. Scheme of TVM 300 et TVM 430 stopping sequences: TVM 300 system TVM 430 system 6
How to ensure safety at 300 km/h? (3) Co-operation between SNCF and ALSTOM to build the TGV, a rolling stock designed for HSL. Motorization concentrated under the power cars Specificities of a TGV train-set: Un train articulé 4 power trucks under each trainset 7
How to ensure safety at 300 km/h? (4) A new dedicated maintenance organisation: No commercial traffic during the night, Massive organisation with dedicated maintenance technical means along the line,(extension of this organisation to conventional lines as more efficient and profitable), Set up of a «sweeping train» with speed limit at 160 km/h every morning after maintenance works and before the first commercial train A centralized dispatching centre grouping train operation and power supply management Adapting safety rules to a new environment: Implementing temporary operating safety rules to be progressively included in general rules Specific measures to be taken in case of incidents on rolling stock Specific procedures to be followed in case of infrastructure incidents 8
Results in terms of safety and regularity Collision with an obstacle on main lines with consequences (assistance needed, injuried people, ) Derailment on main lines 60 50 40 30 20 10 0 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 80 70 60 50 40 30 20 10 0 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 Coll hors LGV Coll sur LGV Déraill hors LGV dérail sur LGV Ponctualité TGV à 05 minutes 100% Atlantique radial 2004 Atlantique radial 2005 Sud-Est radial 2004 Sud-Est radial 2005 Nord radial 2004 Nord radial 2005 TGV 2004 TGV 2005 Objectif 2005 95% 90% 85% 80% 75% 70% Janvier Février Mars Avril Mai Juin Juillet Août Septembre Octobre Novembre Décembre 9
For-coming evolution on Paris-Lyon HSL Paris-Lyon HSL is the first piece of the French current highspeed network Passenger demand is still increasing on this route The opening in 2001 of HSL continuation until Marseille brought more trains on the line section between Paris and Lyon New HSL projects connected with this route will also bring more trains The consequence is a lack of capacity on the Paris-Lyon route 10
Solutions to increase line capacity Increasing rolling stock capacity: TGV Duplex (double-deck) offers +40% seats Modifying train graphic in order to add paths and using ERTMS level 2 combined with current TVM system it is the solution retained for the future Eastern HSL Paris- Frankfurt) 11
