Keeping your Fire Protection Needs on Track

JENSEN HUGHES provides specialized fire safety engineering for all aspects of railway and public transit systems.  Our specialized knowledge of the unique fire protection and life safety challenges encountered in rail stations and tunnels allows us to provide comprehensive solutions to your rail and transit needs.


Performance Based Design

Picture_Section 1 PBD- Sectors_Transportation_Rail and TransitJENSEN HUGHES is experienced in a wide variety of performance-based fire protection and life safety design approaches for supporting alternate methods of compliance. JENSEN HUGHES staff serve on the technical committee of NFPA 130, Standard for Fixed Guideway Transit and Passenger Rail Systems, and can help you navigate the approval process for your railcar, station, and tunnel fire and life safety systems.  Our services range from the application of computer-based fire models and egress models to fire alarm and fire suppression systems design, smoke control system design, and other specialized applications.  We can provide comprehensive performance based design for your rail or transit system that encompasses tunnel, station, and railcar fire safety, as well as the complexities arising from the interaction of all these elements in a modern transportation system.  We also provide peer review services for rail and transit system fire protection and life safety designs.


Modeling Services

Picture_Section 2 Modeling - Sectors_Transportation_Rail and TransitJENSEN HUGHES engineers use a wide variety of computational models to assess the fire and life safety for rail and transit tunnels, stations, and vehicles.  These range from fire and smoke movement models used to design ventilation systems to comprehensive egress models.  Such models are used in performance based designs for tenability analysis of fire protection and life safety systems.  We also perform thermal and structural analysis models to determine thermal and structural effects on the tunnel or station structure due to fires.  JENSEN HUGHES has also developed fire growth rate and burning rate computer models for rail vehicles. The models are used to develop design fires for tunnel and station fire protection design and provide input to the fire safety design of the vehicles themselves.


Tunnel Fire Research and Development

JENSEN HUGHES conducts research and development to address the unique challenges of tunnel detection and suppression.  We have conducted in-situ research Picture_Section 3 Tunnel R&D- Sectors_Transportation_Rail and Transitand testing of a wide range of detection systems in the Lincoln Tunnel as part of our work for the Fire Protection Research Foundation.  JENSEN HUGHES has participated in and managed research programs to develop water mist protection for tunnels in Europe and has developed new capabilities to allow the Fire Dynamics Simulator (FDS) model to model the thermal management provided by water mist in tunnel fire scenarios. This advanced work complements our long standing expertise in foam sprinklers developed through our research for the US Navy.
