Railroad Testing Services
How do you supply railroad testing services for a 10-car train that is over 600 ft. long, weighs over 1 million lbs., requires 6,000 Amp at 600 VDC to operate, and is moving at 50 MPH? By assembling a team of engineers from several disciplines within our lab, DTB has developed the instrumentation, methods, and expertise to perform EMC acceptance testing on the newest technology subway cars. DTB is known worldwide for its excellence in engineering and testing services for the development and ultimate approval and acceptance of rail and mass transit products. We provide 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 industry.
In the Industry…
When the New York City Transit (NYCT) placed into service the “New Technology” subway cars, DTB successfully performed the EMC acceptance testing for each new train model.
