The reliable operation of diesel locomotives in desert conditions demands specific adaptations to cope with extreme temperatures, low humidity, and sand ingress. David Babinec, locomotive model line manager for EMD explains the development of motive power for some of the toughest environments on earth.
A sustainable increase in natural gas supplies is resulting in efforts to explore its use as a viable alternative to diesel for powering locomotives. While LNG is preferred over CNG, Martha Lenz, director of engine systems with EMD, explains that several technologies for combustion of natural gas in locomotive diesel engines are currently under evaluation.
