On board the Lake Shore Limited Boston Sleeper 4820 car. Viewliner 62017. Left Chicago with only one of two AC units working. Of course the Roomettes are the ones with out AC. A Tour group is filling most of this car, and will be getting off in Buffalo. A wee bit muggy last nights with a lot of interesting accents from the guest. Hopefully Boston will have more time and be able to apply more effort in fixing this issue. However really hoping Amtrak spends some of that money there saving with the dinner cut backs on the basis items, like cleaning and state of good repair. Part of me is happy that my sleeper was not pulled, and my trip converted to coach. The other part just want it to be a bit cooler. Side note only one red cap working this train in Chicago. Several unhappy passengers.
