This article obviously needs globalization. Not mentioning major Continental concepts and companies is certainly an ommission that must be fixed. In addition, it seems to me that not even overseas, especially North American practice is sufficiently covered (but I might be wrong here, and not much can be said about lever frames e.g. in the US). haraldmmueller 17:44, 7 September 2014 (UTC) — Preceding unsigned comment added by Haraldmmueller (talk • contribs)
- One of the main editors here and on the Signalling control page is rather critical of contributions so instead of getting into Talk page fights I washed my hands of the whole mess and informed him that he was more than welcome to do a better job. That was in 2008 and the information has been pretty much gone unchanged since then.Sturmovik (talk) 13:50, 8 September 2014 (UTC)Reply
