Siemens To Lead Signaling Upgrade Project

Posted on January 19, 2010

The Port Authority Trans-Hudson Corporation (PATH) has placed an order worth US$321 million with a consortium led by Siemens Mobility for the design, manufacture and installation of a new communication-based train control (CBTC) system. Upgrading the PATH system to the CBTC will increase the system's throughput to meet future peak time demands, increase safety and reliability and reduce ongoing maintenance costs. The project is due to be completed by 2017.

The PATH rail system is over 100 years old and connects the states of New York and New Jersey to the World Trade Center and Herald Square in Manhattan and includes two tunnels under the Hudson River. PATH operates 24/7, running its trains on a total of 69 track km and connecting 13 stations. With reconstruction underway for the World Trade Center site, forecasts project that the daily volume of 240 000 passengers will increase to 290 000 riders per day.

To implement CBTC technology, specialized computer and communications equipment will be installed on many of its rail cars. Siemens will supply its Trainguard MT CBTC equipment for 130 of the 340 new railcars currently being procured by PATH, with an option to equip up to 90 more cars.

A new Siemens-provided train supervision system will help PATH operate more efficiently and know exactly where each train is located in its rail network. The Siemens-led consortium includes Invensys Rail Corporation (formerly Safetrain Systems) and D/A Builders, LLC, a joint venture between Daidone Electric of Newark, New Jersey, U.S.A., and Aldridge Electric of Libertyville, Illinois, U.S.A.
