* Or L..as this area once had, long ago
As to frequent evening service, I think a lot of people (even transit planners) don't realize how many people actually "go out" at night and want to be able to get home easily. Alas, CTA cutbacks going back 20 years (and incrementally since) gutted a lot of not only owl service but regular routes after 10. I've seen so many people, since and STILL, who can't comprehend how or why there is no bus for the last leg of their journey. I've advised so many people over the years how to, possibility, get to (or close) where they are going via another route still running. And neither do such cuts take into account shift workers, who may need service at 11 or till midnight.
On this very Metra route (well, the MD West) I was once taken back to a suburban station after visiting friends in Hanover Park, to catch the last inbound train on a Saturday night. "Probably pretty empty train?" they mused. "Oh, no! Several cars will be full," I noted. They were shocked and wondered why or where people could be going that time of night. They had no idea that, aside from those headed back to the city, lots of young adults were going into town to party.
