Talk with me here!
Hi,
Well, I'd agree that defining these terms and determining where to draw the dividing line is difficult - and I also agree that RER is equally problematic. I suggest you raise the question of these two systems on the talk page (and also your renaming suggestion, perhaps).
But see the previous discussion: Talk:List of metro systems/Archive 2#Brazil rail systems
Assuming they get restored I think the opening date should be the date of inauguration of (eg) Supervia itself rather than that of the commuter lines that it took over.

My fault probably for referring you to it (and the Wiki's fault for allowing you to write there!), but you've put your comments into an archive talk page - you want to add them to the live talk page (Talk:List of metro systems). Bagunceiro (talk) 14:50, 8 September 2011 (UTC)
