Siemens to supply substations for Dallas

Posted on July 31, 2007

Siemens Transportation Systems Inc. won a $30 million base contract this month to supply Dallas Area Rapid Transit (DART) with 24 thyristor controlled rectifier substations for the agency’s latest corridor expansions.


The contract includes an option for an additional 14 substations. Siemens' Sitras Thyristor Controlled Rectifier (TCR) units are used to supply power to DC railways. Up to a certain loading current, they are capable of keeping the supply voltage of a substation to an almost constant level.


When compared to standard substations, the Sitras TCR substation is more efficient, reducing voltage drop and allowing the distance between substations to be extended.


The first substation is scheduled to be delivered by October 2008 with all 24 to be completed by 2010 and by 2011 for the added option. The DART substations are based on those that Siemens supplied to Valley Metro in Phoenix.
