As part of the security measures for the NATO Summit taking place in Chicago over the weekend, Metra is prohibiting large luggage and drinks on trains for the duration.
The last day of the conference will be Monday, May 21, and it will surely be an ugly Monday with no morning coffee on the trains. (Because of heavy passenger loadings, the bar cars have all been converted for passenger use. I wonder if the ban also applies to the one remaining subscription parlor car.)
On Saturday and Sunday, there may be Amtrak passengers connecting to and from Metra, and their luggage has to be left at Union Station, or ??? (As if the Metra or Amtrak schedules pay much attention to connectivity anyway.)
