For metro systems it is becoming common to incorporate open gangway rolling stock with no fixed doors between carriages to improve passenger experience, as it creates a singular open space. A consequence is that in the event of a fire combustion products are able to spread throughout the interior of the train. This paper investigates the differences in smoke behaviour between rolling stock with fixed inter-carriage doors and those with an open gangway design. The goal is both to identify parameters that affect the transport of smoke, as this impacts fire and life safety, and to provide perspective on appropriate design requirements for internal fire scenarios.
