Testing Services for the Rail / Transit Market

During the past seven years, New York City Transit (NYCT) has placed into service more than 1,800 “New-Technology” subway cars with up to 1500 more on the way. And since 2000 through as recently as late 2006, Dayton T. Brown, Inc. has performed the EMC acceptance testing for each new train model.

So how do you test a ten-car train that is over 600 feet long, weighs over one million pounds, requires 6000 amps at 600 Vdc to operate, and is moving at 50 mph?

By assembling a team of engineers from several disciplines within our lab, Dayton T. Brown, Inc. has developed the instrumentation, methods, and expertise to perform EMC acceptance testing of the newest technology subway cars.

Dayton T. Brown is known world-wide for excellence in engineering and testing services for the development and ultimate approval and acceptance of Rail and Transit products.

DTB provides a wide range of in-lab and on-site EMC and Environmental simulation testing services.

Testing is performed in accordance with the latest standards and tailored transit authority specifications.

In addition, DTB is a member of RSSI (Railway Systems Suppliers, Inc.), which is a trade association serving the communication and signal segment of the rail transportation industry.

Specifications Include:

Onsite Surveys Include:

On-site vibration surveys have been successfully completed by identifying and reproducing the field levels in the test lab to simulate real world environments. Large chambers which accommodate multiple systems simultaneously improve scheduling translate into a very cost effective approach.
