During the production of the series between 2003 and 2004, four episodes were aired on Global Television Network during the week. However, in 2005, this was reduced to three. The series dealt with such controversial issues as the adoption of babies by gay couples, in vitro fertilization, single parent families, and euthanasia. A number of events occurred which would be unusual on a real commuter train, including the death of a passenger, a beating, a shooting, an escaped snake, a party, and sex in the train washroom.
