Testing Services for the Rail / Transit Market


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.


For example, when the New York City Transit (NYCT) placed into service the “New-Technology” subway cars, Dayton T. Brown, Inc. successfully performed the EMC acceptance testing for each new train model.


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.
