When we lived in Roselle, we saw theater shows in Chicago several times per year on Saturday nights. Rarely was Metra an option. At that time, the MD-W had trains at 10:40pm and 12:40am. 10:40 was too early for most shows (many ended after 10:30pm) and we were not going to wait until 12:40am.
When we did, the 10:40 was always a little frustrating. It appears they had a 20 to 30 year old service plan which called for only opening two cars. When the train crew made their way from the gate to the train at 10:39pm, they’d discover crush loads in those two, open some more cars, but we wouldn’t depart until 10:42 or 10:43 as they waited for people to spread out. And this happened every single time.
I'm not entirely sure Metra understands their non rush ridership well. What you note about theater or concert goes is one important example. (As it's a significant amount of activity downtown and accounts for a LOT of riders.). Lyric Opera even changed their start times not too long ago to accommodate patrons who were tired of having to wait for later trains, meaning suburban riders might not get home until after 1 A.M. Another are game day riders, who make up a lot of passenger load when one of the sports teams is playing. Old service plans is probably spot on analysis.
