Hard to make this article close to complete
After looking through many railway maps globally (e.g. Google, open street) I would say that the number of horseshoe curves is almost endless, much contrary to spirals which I would estimate have reached here on Wikipedia far beyond half of all existing. ziczac is also quite uncommon but far more common then spirals, especially when including single reversals.

Maybe one shpould mnake that clear in the artyicle by stating something like: Horseshoe curves are uncommon on single track mainlines and very uncommon on double track mainlines. On sidelines and especially narrow gauge lines are horseshoe curves common in hilly terrain all over the world.

My english is not so good so please correct. Tord Björk (talk) 23:24, 15 January 2013 (UTC)


 * I think it is difficult to make such a general statement without proper source, but the list of examples should perhaps distinguish between main lines and narrow gauge lines. --— Erik Jr. 15:00, 19 February 2016 (UTC)
