Coke and Coke Zero! As Amtrak Train 161 pulled into the Old Saybrook, CT station on the morning of Saturday, November 16, 2019, it passes CT Rail 6695 which has arrived a few minutes prior on Train 3610. While Amtrak ACS-64 606 was "wrapped" with an ad for Coca-Cola to note Amtrak's switch of beverage providers, the CT Rail current corporate scheme has been nicknamed "coke zero" for its black and red.
