CPTM, part of the Greater Sao Paulo commuter rail network, has six routes serving 89 stations, and operates 162 route miles of line. It carries more than 1.7 million daily passengers.
The four 2,000 hp EIF2000 locomotives being built for CPTM incorporate the Tenino, Wash.-based company's Sygnet Power Module (SPM), a self-contained, integrated system that uses a Cummins QSK-series prime mover (diesel-electric engine), traction alternator, cooling system, dynamic braking system, and control systems in one standard configuration.
The power module is designed to allow for quick access and diagnostics, maintenance, reliability, reduced operating costs, and improved return on investment, the company says.
The Sygnet system also includes a telematics monitoring and reporting system that continuously checks the operational status, to aid in fuel efficiency, reduced emissions, and lower noise levels.
"Our partnership with Cummins, and our controls, allow Sygnet Rail Technologies to produce a line of extremely reliable, fuel-efficient, environmentally friendly, and cost-effective locomotives," said David Swanson, Sygnet president and CEO. "These locomotives will provide CPTM with high-quality performance and will be the cleanest locomotives ever delivered in Latin America."
The locomotives delivered to CPTM will also comply with the Kyoto Protocol.
