Last time I took Amtrak from DC to Chicago, there was still a smoking section at one end of the observation car. Some drunk really raised a ruckus after being cut off and getting told that he couldn’t smoke during the movie being showed on the monitor at the opposite end of the observation car. He ended up getting so obnoxious that he was put off the train at some tiny station in Ohio where some members of the local PD were waiting for him.
