Question to the experts, out of curiosity, as I noticed it during the electrification transitions... When you open the main circuit breaker under DC electrification two indicators are lit: the red (the main circuit breaker) and the yellow (for the battery I presume). But under AC or LGV modes only the red is displayed. Why is this? I´m not familiar with the real train. If you do it when raising pantos before service start at Marseille or Avignon you have the same results. At Marseille which is DC the two are lit but at Avignon which is LGV only the red is lit. Cheers
