Implementing Positive Train Control
Technology will help reduce accidentsIn response to several fatal accidents on other rail systems between 2002 and 2008, Congress passed the Rail Safety Improvement Act of 2008, mandating implementation of positive train control (PTC) systems on rail lines that:
Impact on DART
DART also is teaming with the Denton County Transportation Authority to implement PTC on the A-train, whose 21-mile corridor is shared with the Dallas, Garland & Northeastern Railroad.
Together, the transit agencies will implement a regional solution for the two North Texas commuter railroads, basing their PTC system on technology used by the nation's major freight carriers, including BNSF and Union Pacific.
Because DART Rail runs on dedicated track, it is not governed by the rule. Future commuter rail lines - such as The T's TEX Rail project and DART's Cotton Belt Corridor - will have PTC built into the design.
"Interoperability among railroads is the biggest challenge to PTC," said Norma De La Garza-Navarro, DART's vice president of commuter rail and railroad management.
These projects are estimated at nearly $35 million for the TRE and $23 million for the A-train. The North Central Texas Council of Governments is contributing $25 million and the three transit agencies must cover their portion of the balance. Work is anticipated to begin later this year and be complete by 2017.
