Notes from Underground
Ben Soo and I went on the Un Métro la nuit tour late late Friday night along with 3 dozen others. I’ve posted a quick photographic travelogue here with explanations.
It was great fun to see the stuff you never see and the aperçu really did give me a better appreciation of the constant effort that keeps the metro system running day to day.
To answer a question asked here on the blog: why can’t the system run 24/7 like the New York or London subway systems? The answer is that in most of our system we run both tracks through the same tunnel. In those older systems, with separate tunnels, at night you can run alternating trains in one tunnel while you clean and repair the other. Here, we’ve got to close the system for a couple of hours every day to do the maintenance work.
