I was a bit bored last time when I drove in a night scenario on Edinburgh-Glasgow and so I came to the idea to just press any of the announcement buttons in the train and quite funny things happened, like that: Welcome to this - first class... Welcome to this - Welcome Welcome to this - testing, testing! First class is in - this is Glasgow Queen Street. Welcome - Wel - W - W -W - W - W - Welcome... The rest i can´t remember but it was really funny and I almost fell from my chair What do you think? Have you ever tried this?
