With Railway Age since 1992, Bill Vantuono has broadened and deepened the magazine's coverage of the technological revolution that is so swiftly changing the industry. He has also strengthened Railway Age's leadership position in industry affairs with the conferences he conducts on operating passenger trains on freight railroads and communications-based train control.
CN’s new Fuel Management Excellence (FMX) program is providing the railroad with significant increases in fuel efficiency and environmental benefits.
“FMX is a vital part of taking our precision railroading model to the next level,” said Keith Creel, executive vice president and chief operating officer (pictured). “Sophisticated fuel efficiency and monitoring systems will aid our efforts to measure and report reductions of greenhouse gas emissions and the scope of the carbon footprints of CN and our customers. All this is vital as fuel prices remain a challenge and freight customers put greater emphasis on sustainable transportation options. CN is making significant strides in improving the fuel efficiency of its freight train operations, obtaining important sustainability gains, and delivering a cost-effective transportation service through a series of initiatives, including the acquisition of modern locomotives, new technology applications to existing locomotives, enhanced analytic abilities, and employee training.”
CN’s FMX program includes:
• Acquisition of new fuel-efficient locomotives. In 2010 CN purchased 102 new high-horsepower locomotives, as well as 102 second-hand high-horsepower locomotives that are being upgraded. These locomotives are approximately 15% more fuel-efficient than the ones they replace and comply fully with applicable regulatory requirements for reduced locomotive exhaust emissions.
• Installation of Wi-Tronix telemetry systems on high-horsepower locomotives. Wi-Tronix provides real-time information about locomotive and train performance through remote measurement and reporting of data, including precise fuel consumption, to an off-board CN computer system at regular intervals or at request. The technology allows CN to optimize the match of locomotive horsepower to the trailing tonnage of the train by isolating or shutting down locomotives and reducing throttle settings. It continuously scans train operations for the proper application of train handling rules to optimize fuel use, determines when and where fueling is required, and ensures temporarily inactive locomotives are shut down. CN expects to equip up to 1,200 high-horsepower locomotives with locomotive telemetry technology by 2013.
• Trip Optimizer technology from GE Transportation. Trip Optimizer is a train “cruise control” system that follows a pre-determined speed trajectory over a GPS track map to optimize fuel consumption. It minimizes braking by planning miles in advance for speed zone and terrain changes. CN’s Vancouver-Montreal corridor is fully mapped for this technology, and CN is now moving intermodal trains equipped with the technology over key sections of this corridor. By September 2011, CN plans to have intermodal and merchandise trains in the corridor running with Trip Optimizer. CN has 125 locomotives with Trip Optimizer and plans to install this type of technology on up to 400 locomotives by the end of 2013.
• Installation of Auto Engine Start Stop (AESS) technology, which automatically shuts down an idle diesel engine, while keeping the locomotive in the proper operating state to start on demand. CN has more than 600 locomotives with this technology, and plans to apply AESS-type technology on up to 800 more units by 2013.
• Training of train crews and rail traffic controllers. These employees are continually being schooled on best practices, including fuel-efficient train handling techniques, matching power to train tonnage and limiting throttle use, and taking advantage of train pacing opportunities at train meets.
"We are particularly excited about our leading-edge work to set fuel efficiency targets for specific trains by route and to monitor train performance against these goals,” Creel said. “The targets are based on established benchmarks for key fuel consumption variables such as train makeup, locomotives, train handling, route gradients and curvature, and weather. This strategy to produce real-time information by train and by locomotive is truly the next frontier in precision fuel management. CN leads the North American rail industry in fuel efficiency, consuming, overall, 10%t less fuel per gross-ton-mile than the industry average. This has helped CN reduce greenhouse gas emissions and has resulted in the lowest fuel surcharge in the industry, helping our customers save on transportation costs.”
