CSX will be the first to demonstrate Wabtec’s Trip Optimizer Zero-to-Zero system that allows railroads “to start a train from zero mph and stop the train automatically using various controls,” according to the manufacturer. The technology builds on Trip Optimizer, which “has saved railroads more than 400 million gallons of fuel since its inception and reduces CO2 emissions by over 500,000 tons per year,” Wabtec said.
Wabtec’s new Tier 4 switcher modernization program will be used for CSX’s fleet. The program upgrades 40- to 50-year-old locomotives and Tier 0 non-emissions switchers to the latest Wabtec Tier 4 platform, and is said to provide “an additional 20% improvement in fuel efficiency and 90% reduction in emissions.” It does not require a urea after-treatment system. Each re-powered unit “will eliminate up to 90 tons of CO2 and 7 tons of NOx reduction per year,” according to the manufacturer.
