  • Support NCTD’s fleet of 12 DMU vehicles servicing Northern San Diego
  • Optimizes fleet maintenance and availability 

Siemens Mobility was awarded a 12-year Technical Support Spares Supply Agreement (TSSSA) contract by North County Transit District (NCTD) for their fleet of Siemens Sprinter Diesel Multiple Unit (DMU) vehicles. With a value of $80 million, the contract includes base services for the 12-year term with a 3-year option to be performed on a task order basis if executed. These Sprinter DMU vehicles have been in revenue service since 2008.


“NCTD is excited about this agreement with Siemens which complements a similar agreement with Siemens for our Tier IV locomotive fleet.  The two technical services and material agreements with Siemens supports NCTD’s Zero Delay emphasis and will allow NCTD to advance the implementation of a world class rail operations as we insource commuter and hybrid rail operations and maintenance,” said Matthew Tucker, NCTD’s Chief Executive Officer.


“Siemens Mobility is proud to partner with North County Transit District as we optimize fleet availability and reliability in San Diego,” said Michael Tyler, President of Siemens Mobility Customer Services in the U.S. “With fewer service interruptions we are keeping NCTD trains and riders on the move.”


The North County Transit District is a public transportation agency providing over 10.3 million passenger trips annually throughout North San Diego County and into downtown San Diego, California. NCTD covers a geographic area of approximately 1,020 square miles with an approximate population of 849,000 people.


Under the terms of the contract, Siemens Mobility will provide full-time on-site employees for technical expertise, materials management, project management and engineering support.


Siemens Mobility will also provide CorMap services, a digital Maintenance Equipment Asset Management System, to all vehicles in the NCTD rolling stock fleet including bi-level coaches, charger locomotives and the sprinter DMU vehicles. CorMap supports the rolling stock fleet to optimize and reduce maintenance costs by improving data quality while increasing fleet reliability and availability.


More than 130 years of Siemens Mobility maintenance and service support experience worldwide has resulted in optimized processes that ensure improved and sustainable levels of performance. Siemens Mobility believes in a continued focus on innovation in technology, tools and maintenance concepts to ensure high levels of reliability over the lifetime of its vehicles.


As part of this agreement, NCTD’s Siemens DMU fleet will have a wide network of available support including direct, immediate connections to support from local and national Siemens Mobility depots, as well as its corporate services headquarters and plant in Sacramento. NCTD will also have access to Siemens’ exclusive global support network for purchasing, engineering and maintenance innovation.


NCTD is one of more than 35 transit agencies across North America benefiting from Siemens Mobility’s portfolio of rail vehicles, locomotives, components and automation systems. American cities also rely on Siemens Mobility to provide traction-power substations and electricity transmission, as well as signaling and control technology for freight and passenger rail and transit systems.
