Train 48 is a concept show. The entire program is ad libbed by the actors from a rough outline given to them by the producers. The show revolves around a set of unique commuters on a train from Toronto to Burlington. The show is taped each afternoon of the evening performance so the show is topical and up to date. The show needs a couple viewing to truly grow on you. Once you get to know the people and get over the hard to swallow concept that these people would actually become so involved with one another when all they share is a train ride home, the show becomes real fun.
