Hello,
I'm going to ask this question because it has always fascinated me. What happens when you have a station with dual voltage lines i.e. at border stations when there are 2 networks which meet but both have different voltages. Example French/german border stations 25Kv to 15Kv, French/Italian stations 1500V/300V or even French/French stations 25Kv/1500V (eg Marseille st Charles, Albertville or Dôle). Does each track have it's own voltage, thereby necessitating use of diesel locos to transfer the train between the 2, or is there some way of switching voltage between the two? Most networks now have bi, tri or even quad voltage locos to alleviate the problem but what happenened in the 50s and 60s?
regards
Clive
