Back in 2011, when the weekend maintenance disruptions got more aggressive, we were told that the work on weekends and at night and midday would be enough to get the system back to a state of good repair.

I don't like the midnight closing on weekends. It's one thing to tell people they have to drive to Jiffy Lube Live in the outer suburbs.

Motors that are vulnerable to shorting out because of snow ingestion should have snow filters installed over air intakes, and spare motors should be ready to replace any failed motors.

I'm surprised when I see someone doing the logical, commonsense thing: Walk facing the oncoming traffic.

Seems like people could behave themselves without making a calculation regarding how likely or unlikely they are to kill other people.

That's the original problem from which the escalator mess stems. There's just too many of them.

I don't know of any source for online maps showing the platform, stairs, escalators, elevators, mezzanines and other station details.
