Not when you are using a six car train in place of a 12 every 30-60 minutes. It was down to hourly until a few months ago with short trains..It was mostly 30-minute service when I rode it a month ago.
Odd though that Lakeshore is every 15 already! That's far more expensive to run.
UPX been 30 minutes for a year using 2 car trains only.
