Implementation and Maintenance of a TGV Lineby Bernard Schaer, Rhone-Alps High Speed Line, Lyon, France,
Abstract: Because of the success of the TGV in France since the opening date in 1981, SNCF plans to implement 2800 miles of new line in the next 20 years. A new line project poses two management problems: construction cost control and schedule control. A new policy of anticipated request for proposal helps to keep the project in schedule and the costs as low as possible. As does heavy use of the computer in the design stage and in a new track lining method. As a result, 71 miles of new line with ballasted track and numerous structures were built in about 48 months at a cost of $14.3 M per mile. The new track design and an advanced maintenance scheme will reduce maintenance costs to as little as $13,700 per track mile.
