Instead of saving the bar car, the boozy compatriots want to end it? The first one is relatable and sounds like a midlife crisis story where they want to hang on to their vices and crutches and wrong behavior. Perhaps the story is about the last few days with the bar service as they deal with their personal issues and mark the end of an era.
If it's really about the protag(s) ending the service, then it's hard to care for him despite the merit in his objective. He's the party-pooper, the a-hole not minding his own business.
Is most of the script on the train?
I'll stop there because another logline attempt is in order to clarify the intention.
