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#Multi-system units, 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.
