Here's my report:
Trip 1 - LaSalle to Rosemont - 8/4 Noon - trip time 45 minutes. Slow zones between about Addison and Jefferson Park, then free sailing the rest of the way. Trip spoiled by 1-2 minute waits at every stop in the Loop, no idea why.
Trip 2 - Rosemont to LaSalle - 8/4 8:30 pm - trip time 90 minutes. Free saiing to Belmont, then held due to "debris on the tracks at Western" due to the storm. So, horrid trip but not really the CTA's fault.
Trip 3 - LaSalle to Rosemont - 8/5 7:30am - trip time 40 minutes. Free sailing past Jefferson Park, then a short stop while the driver exited the cab to "check something under the first car". All in all, not a bad trip.
Trip 4 - Rosemont to LaSalle - 8/5 2:00pm - 35 minutes. Fast to Jeff Park, then several odd short stops between Addison and Western. Again, not a bad trip.
