1. A suppression system in a safety railcar, the suppression system comprising:
- a source of pressurized water;
at least one suppressor tank containing a suppression agent, each suppressor tank being connected to receive pressurized water from the source of pressurized water to pressurize the suppression agent;
a controllable valve positioned between the source of pressurized water and the at least one suppressor tank to mediate flow of pressurized water; and
at least one spray nozzle connected to receive the suppression agent from each suppressor tank, each spray nozzle being connected to the respective suppressor tank via a rupture disc configured to rupture and permit flow of the suppression agent from the spray nozzle when pressure within the at least one suppressor tank exceeds a predetermined threshold;
the controllable valve being controllable to permit flow of suppression agent in response to detection of a hazardous event.

Abstract
A suppression system for use in a safety railcar may include a source of pressurized water connected to at least one foam tank containing a suppression foam. A controllable valve mediates flow of pressurized water from the source of pressurized water to the at least one foam tank. The controllable valve is controllable to permit flow of pressurized water to the at least one foam tank in response to detection of a hazardous event. A spray nozzle is connected to the foam tank via a rupture disc that is configured to rupture and permit flow of suppression foam from the spray nozzle when pressure within the foam tank exceeds a predetermined threshold.
