A hidden rail yard runs beneath Manhattan’s mega development at Hudson Yards

Hudson Yards is the largest private real estate development in the history of the United States and features 18 million square feet of residential, commercial and retail space. To support a development of this scale in New York City, it was necessary to enclose the site’s existing 30-track train storage yard with an overhead platform. Arup was commissioned to address the heat, engine emissions, and fire scenarios created by the trains running underneath this large platform.

Arup’s interdisciplinary team provided fire/life safety consulting, engineering design, and construction administration and commissioning services for the tunnel ventilation system serving the newly enclosed train shed. The team developed egress strategies for various fire scenarios, including timed egress modeling, and tested, sized, and optimized corresponding ventilation strategies using CFD analysis. 

The final ventilation design includes 3 supply and 3 exhaust fan plants, integrated with the overbuild platform and buildings, and delivering over 800,000cfm in various operating modes.
