I took a trip to my work library today and found training manuals from 1986 that were really well written but looked brand new.
I thought about the person who documented all the wear and tear that happens over the life of a railway when it was brand and the instructor who likely questioned the utility of training such things.
Then I thought about how happy I was to find it on a shelf 31 years later because, as it turns out, 'maintenance free' lasts about 30 years. #smallstories
