Following on from the current theme of underground mass transport systems, this recording was taken at my local metro station, Voltaire. The Parisian metro system is currently experiencing a general upgrade, with each line taking turns to get a makeover. Last year saw line 1 become automatic (i.e. trains now have no drivers) and other lines have seen the introduction of new train stock. Voltaire is on line 9, which is currently seeing new train introduced progressively, running a mix of the new modern trains and the MF-67 trains that are over forty years old.
From a soundscape point of view, I love the older stock! They have a real old-school sound to them which I will surely miss once the new stock is fully integrated and the old stock removed forever.
