<p>An 'A line' Subte subway at rest in Buenos Aires' FilePlaza de MayoFile station early on a Saturday morning.

I'd judge this train to be in better-than-average shape, by local standards.  An operator told me that the fleet now includes forty new trains from China -- at least if I didn't miss something in translation, and I might have -- but I also saw first hand that it includes some real beaters.  Buenos Aires awarded me with the single most gruesome subway ride I've taken to date, as shall be explained in a photo caption elsewhere in this set.
