Talk:Multi-system (rail)

Disambiguation
I think there needs to be a disambiguation here between multivoltage and multi-country locomotives = eg http://regulation.upf.edu/utrecht-08-papers/mlaperrouza.pdf page 2 clearly uses Thalys and Cisalpino as examples ie Multi-system locomotives already ensure reliable rail transport (e.g. the Thalys between France and Germany or the Cisalpino between Italy and Switzerland)

Also re- worldwide view - are multisystem locomotives used anywhere except europe ?? .. Excluding S. Africa.Imgaril (talk) 22:14, 23 June 2011 (UTC)


 * Yes, around New York City, there are several different systems, which is why there's an image of Metro North's M2 railcars (run on third-rail and overhead lines). New Jersey Transit also have locomotives such as the ALP-46, which run off 25 kV 60 Hz, 12.5 kV 60 Hz, 12 kV 25 Hz, all overhead. Tim PF (talk) 22:45, 23 June 2011 (UTC)
 * Do you know enough to write a section on that, explaining why there are different voltages used, or about that technology?Imgaril (talk) 06:51, 24 June 2011 (UTC)


 * Possibly. Do I have the time at the moment, probably not.  I did add the see also to Railway electric traction, with the intention of moving much of that section to this article (or the alternate would be to improve that section, and change this to a redirect). I note that some NYC area bits are mentioned there.  Tim PF (talk) 10:48, 24 June 2011 (UTC)
 * Oh well never mind - maybe later - I wont do the US one as I know nothing about, but I'll keep an eye out for other examples. I see that indian railways has more than one voltage, but I don't know anything about that either.
 * Did you have any objections to the disambiguation - there are two possibilities as well - expand this article to include multi-safety sytems, or have a separate article.Imgaril (talk) 17:01, 24 June 2011 (UTC)


 * I think that Indian Railways intend to convert the Mumbai Suburban Railway to 25 kV AC, but I cannot find a source for that at the moment.
 * I think that "multi-system" may be a bit like hybrid locomotive, which gets mis-used for electro-diesel locomotives. When I started this article, I had only seen multi-system refer to the electrification systems, but it's not the first time I've heard mention of the safety systems, although I'd like to see a reliable source for it.  The one you quote above certainly refers to different electrification systems, and about the first reference I can find to "multi-country" is for the EMD Series 66 diesel locomotive.
