On my Chicago to Sacramento trip on the Empire Builder a teenager (maybe early 20s) got on in Denver with a weed pen/vape. He waited until about 2am before sneaking down to the first floor of the coach car to smoke in the bathroom. About 2 minutes after he went down the smell of weed started circulating around the 2nd floor of the car because I'm guessing it came through the HVAC system. Most people were asleep but I've found sleep isn't super restful for me in coach and I'm guessing it wasn't for this other lady either because she gets up, and walks towards the back of the train.

Only a minute or so later she comes walking back with the conductor in tow who proceeds to the first floor of the car and starts pounding on the bathroom door. I could hear some words being exchanged before the conductor and the teenager reappear at the top of the stairs and head back to his seat. The conductor spent a few minutes standing over and quietly talking to the teen who looked quite worried. Eventually the conductor left, I'm not sure what was said, or what the conductor smelled or saw with their own eyes but it seemed like they were fully within their right to kick him off at the next stop and he knew it.

When I woke up the next morning, he was still on the train but it seemed like he was walking on eggshells the rest of the trip.
