CREATING HIGH-SPEED RAILWAYS Track, Overhead Catenary and Substations. East-European high-speed line A MAJOR RAIL INFRASTRUCTURE CONSTRUCTION AND MAINTENANCE COMPANY
EXPERIENCE MAKES THE DIFFERENCE Colas Rail has more than 25 years experience in designing, maintaining and renewing High-speed Lines around the world France South East high-speed line 1st section - 1981: at 260 km/h operating speed & 2nd section - 1983: Paris/Lyon in 2 hours Atlantic high-speed line: Paris/Le Mans/Tours at 300 km/h operating speed - 1989 / 1990: railway track, overhead contact wires and Northern high-speed line: Paris/Lille/Calais - 1993: railway track, overhead contact wires and Mediterranean high-speed line: Lyon/Marseille - 2001: railway track, overhead contact wires and East European high-speed line, 1 st & 2 nd sections: railway track, overhead contact wires and Rhine-Rhône high-speed line: design studies and execution, supplies, installation and putting traction power equipment into service Brittany-Loire high-speed line: a new line between Le Mans and Rennes (overhead line works) 185 km of double track / 45 km of connecting lines Nîmes Montpellier rail link (CNM): 60 km of new line; 20 km of connecting lines; a 20-year maintenance contract. Working with Oc Via, Colas Rail is responsible for the design and construction of the line, and ensuring its running, upkeep, maintenance and renewal programmes until 2037. 574.8 km/hour is the latest world speed record performed on an infrastructure installed by Colas Rail, on LGV East European Line. Belgium Line 1 Brussels/France 1997 Line 2 Brussels/Liege 2002 Line 3 Liege/Germany 2007 United Kingdom High-speed 1 (Channel Tunnel Rail Link Section 1) 2003: railway track, overhead contact wires and Germany Frankfort/Cologne 2002 Nuremberg/Ingolstadt 2006 Korea KTX Seoul/Daegu 2004 Morocco Colas Rail is playing an active role in the construction of the first high-speed line on the African continent, on the Casablanca to Tangiers section. 180 km of double track at 320 km/h 400 km of 25 KV overhead lines Workshop & maintenance Concrete track Colas Rail has made a substantial contribution to the development of concrete track techniques, notably on the German market, a precursor in the field. As early as 1972, Colas Rail worked on the Rheda station site during the first concrete track experiment. In 2002 Colas Rail completed the Cologne-Frankfurt line, and went on to produce concrete tracks in the UK and France. Colas Rail has always been involved in discussions and improvements on one of the world s highest-performance systems.
East-European high-sp DESIGN Performance, System Integrity and Safety Colas Rail has a long established design process that has resulted through its vast experience in high-speed Lines (TGV) with the knowledge of different technologies. This allows Colas Rail to develop detailed designs that fully integrate the various subsystems with physical and functional interface management down to individual components. Colas Rail has developed simulation tools (overhead catenary pantograph current collection ) and computer-aided design programmes that not only ensure that safety and required performance is achieved, but also allow the application of standards and components to produce systems that are specific to a particular country. For example the design of ballasted and non-ballasted (concrete slab) track. CONSTRUCTION Precision, Logistics and Methodology Track and overhead catenary are installed with great precision to tight tolerances to achieve performance and safe operation. Proven construction methods use road and rail supply systems for handling major bulk and high volume products (ballast, sleepers, stanchions, long welded rails ). These can require complex site facilities such as railheads for storage capacity, preassembly workshops and train marshalling. Methods and staging of the work to optimise construction logistics such as, laying signalling cables in troughs before the installation of overhead catenary stanchions.

COMMISSIONING Verification, Testing and Validation The testing from individual components to a full transportation system with many trains running is carried out by phasing the commissioning of the various sub systems and a ramping up of capacity. The thoroughness and traceability of the testing and validation process is the key to determining the system performances and safety of the high-speed lines. eed line Nîmes Montpellier high-speed line Brittany-Loire high-speed line
SAFETY Safety is paramount while operating the high-speed line during the construction and commissioning phases (25 KV electrification and train management) and requires a robust construction & commissioning set of rules. Marocco high-speed line RENEWALS Brittany-Loire high-speed line Fast Removal and Renewal. Specialised plant and equipment allows highly mechanised and rapid renewals of the High-speed Lines. The use of high output track renewal trains optimises short possessions for the total replacement of the track with hand back of a fully operational railway. Renewal of contact wires and overhead catenary uses dedicated specialised engineering trains.
