PTC for the Rail Industry

Railroad systems across the country are required to comply with the Rail Safety Improvement Act of 2008 and the Federal Railroad Administration’s PTC regulations. These requirements include the delivery of a PTC Implementation Plan, a PTC Development Plan, and a PTC Safety Plan. The PTC system must be designed to prevent train-to-train collisions, over-speed derailments, incursion into established work zone limits, as well as the movement of a train through a switch in the wrong position.

DTB’s team of subject matter experts and technicians offers exceptional assistance in meeting these requirements and deadlines. We help throughout the implementation process – from the development of the test plan, all the way through testing. We provide both the equipment and the personnel to operate and verify the performance of the PTC communication systems.

DTB's Dedicated PTC Lab

The DTB lab serves railroads and suppliers with qualification testing, diagnosis, and troubleshooting PTC and PTC II communications systems.

Interference, integration, and interoperability testing and evaluation in the field is costly, time consuming, and extremely difficult to perform consistently in densely populated areas.

Utilizing a controlled lab environment allows our engineers to demonstrate functional performance, evaluate protocol, capacity and throughput, detect issues, and develop mitigation. Additionally, quick identification and cost-effective solutions found in the lab will reduce risk and improve schedules while allowing the rail line to maintain revenue service continuity and safety.
