I'm interested in this New Zealand case. Obviously they are 'main lines' in their country context, but are they definitely mostly single track? I couldn't find anything with a quick look at the NZ rail article (perhaps its just common knowledge?). I'd be interested to know if NZ is the exception that proves the rule or whether there are other significant systems with single track main lines?

Yes, almost all railways in New Zealand are single track. With the obvious exclusion of crossing loops, yards, etc., the

Adelaide-Darwin Railway could be economic. - Axver (talk) 22:11, 5 December 2007 (UTC)[reply
