[edit] Proposed Rename

The existing name gives no hint that the topic is other than a general purpose electric transmission system. The name should make it clear that this is localized and special purpose. To most of the world AC by default means 50 or 60 Hz.LeadSongDog 18:30, 29 August 2007 (UTC)

[edit] Error

It is actually 16 kV that is used in Sweden and Norway. Bjorn Knutson 18:21, 7 December 2007 (CET).

The nominal voltage is 15 kV (see for instance http://banportalen.banverket.se/Banportalen/upload/1080/Jarnvagsnatsbeskrivning_T07.pdf ). On Banverket's net the maximum voltage at the point of consumption (the locomotive) is specified as 17.25 kV (15 kV +15%) and the minimum voltage is specified as 13,5 kV (15 kV -10%). To compensate for voltage drop along the catenary, the voltage at the feeder station's terminals are usually 16 kV or slightly higher. Unfortunately, Banverket adds to the confusion by stating 16 kV in many non-technical texts, such as press releases regarding accidents. All of this is for Sweden, I can't say anything about Norway but I would guess they have adapted the same EN-standard for interoperability reasons. JTragardh (talk) 07:54, 30 December 2007 (UTC)

[edit] First tested...

The technique for this electrification system was first tested in Germany on the Höllentalbahn during the 1930s and 1940s.

Sounds "a bit" questionable to me since the Gotthardbahn was fully electrified using this system in 1922... I think the first tests in Switzerland were run between Seebach and Wettingen around 1918, see also List of stock used by Swiss Federal Railways. --Kabelleger (talk) 22:20, 15 January 2008 (UTC)

It seems that this sentence was torn out of the right context with one of the last edits. It seems to belong to the 50 Hz stuff. --Kabelleger (talk) 00:18, 16 January 2008 (UTC)

It was a stray paragraph at the bottom which I moved up the page. The whole article still needs redoing - it looks like it started a a babel fish translation of the German article. I'd give it a go but I can't read the German reference materials. Railwayfan2005 (talk) 18:33, 16 January 2008 (UTC)

I've done some more copyediting, and removed that very inaccurate sentence over; I have references at my side stating that this system was used in Norway in 1922, so it could not have been developed during the 1940s. Arsenikk ^(talk) 15:57, 8 June 2008 (UTC)
