>>1170569Most operators will have part of their high speed fleet compatible with neighboring countries systems. For instance, the French TGV fleet comprises :
>dual current sets (1.5 kV DC / 25 kV 50 Hz) for the national service. All TGVs can operate under those two currents by default.>tri current sets for service to Germany/Switzerland able to operate under 15 kV 16.7 Hz>tri current sets for service to Belgium/Italy able to operate under 3 kV DC>quad current sets used on the Thalys services to Germany and Benelux (15kV AC and 3kV DC)>formerly Eurostars were also quad systems, being able to operate under the Begian 3 kV and, formerly, the standard British 750 V DC by third rail (they dropped the transformers and collectors with the opening of HS1, downgrading them to tri-current sets)As mentionned earlier, the issue isn't so much the different electrification systems than the different signalling systems. A Thalys PBKA trainset for instance is fitted with :
>TVM for French and Belgian (Line 1) high speed lines>KVB for French standard lines>ATB/TBL for Belgian and Dutch standard lines>PZB for German standard lines>LZB for German standard lines>ERTMS for Belgian (Line 3) and Dutch high speed linespic related: the dials and signal lamps for all that shit (pre ERTMS refit), covering most of the center panel and the one directly to its left
