Boarding the wrong train is common also, I suppose. This morning the gate agent at Chixago told each passenger before going to the platforms to board the train on the RIGHT on Track 22. Yet, the first family in front of me (iI was the second out the door) boarded the first open car door they saw on the LEFT on Track 22. I did my Good Deed for the Day and alerted the conductor on the correct train (381) as I reached his post farther down the track -- he couldn't see what had transpired from his position. When he lifted my ticket 15 minutes later, he thanked me a second time and said he got them off that set of equipment going nowhere.
