The show was broadcast daily, and recorded the same day. It took place in a railway car of a GO Train on Lakeshore West line returning from Toronto to the suburb of Burlington, Ontario, and followed the lives of 12 daily commuters through their interactions. Although major plot lines were written in advance, much of the dialogue was improvised by the actors. The entire series was shot on a 64-foot replica of a GO Train Bombardier BiLevel Coach, which kept production costs to a minimum.
