THE French government's strong objection on safety grounds to the operation of distributed-traction passenger trains in the Channel Tunnel, as planned by Eurostar and German Rail (DB), has been overruled by the European Railway Agency (ERA). ERA confirms that the current rules authorising vehicles to operate in the Channel Tunnel "do not explicitly prohibit distributed power, provided an equivalent level of safety" to the existing Eurostar trains, which have power cars at each end, "is demonstrated."
