numerous road-rail vehicles to be organised and set up.new catenary equipment delivery in the area.In order to renew these two types of catenary (1,500 VDC and 25,000 VAC), logistical resources are generally heavy to implement: What new challenges does the renewal of the catenary impose? It was in this context that the High Output Catenary Renewal Trains appeared. The 1,500 VDC catenary is generally older, with some sections of track having poles that are almost 100 years old! Given the density of the electrified network in France, new high-performance trains were needed to complete this work within a suitable timeframe. In addition to the renewal of the catenary wires carried out with rolling and unrolling trains, SNCF studies have shown that it is also essential to replace the support on the 25,000 VAC catenary and the entire pole and support on the 1,500 VDC catenary. This electrified network is 65% divided into 25,000 VAC (volts in alternating current) and 35% of the network into 1,500 VDC (volts in direct current). What is the situation of the catenary network in France?įrance has nearly 30,000 km of railroads, half of which are electrified, which must be regularly maintained to ensure the safety and continuity of rail traffic. Unrivalled performance in catenary renewal has already been achieved. In 2021, a second rapid catenary suite will operate on the 1,500-volt network. After long months of design and manufacture in cooperation with Colas Rail and TSO Catenaries, the first GEISMAR SRC fast catenary suite is at work every night on the 25,000-volt network. Why not replicate this approach for catenary work? This is the specification that has been proposed in France by SNCF Réseau to renew almost 16,000 km of electrified track. High output renewal trains are well known in the track world for renewing rails, sleepers or ballast with high efficiency.
