This I agree with. Back in the 80s I toured Boston's Red line (subway) maintenance station as part of my internship with the DOT. Back then, the red line was considered the model for which other maintenance stations would copy. The trains were driven in over maintenance bays and two teams went to work on each and every train: one above for cleaning and items like lights/doors, even ads, and one in the pits for the power system, brakes, etc. They were able to scrub all the trains clean every night between shutdown and start up. I forget what those hours were, but to be sure it wasn't any longer than what Disney has, and they have more trains. When job cuts started coming along in the 90s, that's when the maintenance started dropping.
It's all about manpower. They don't even need to bring them into the 'roundhouse' (which isn't round, LOL) to clean.
Being from boston generally its 1AM to 430 AM when the red line shuts down for maintenance, If you are a regular rider you notice they STILL clean the cars every night because if you are an early AM rider the floors have been cleaned and you can tell
