An 8,500-hp gas-turbine-electric locomotive

AFTER almost a decade of development of the gas-turbine-electric locomotive in practical service, this type of motive power has emerged from the experimental stage. One result of its acceptance in heavy through-freight service has been the demand for a unit considerably more powerful than those previously built. This has been designed and is now under construction. It embodies the same basic design principles found in the smaller units now in service. Wherever possible, advantage has been taken of the lessons already learned to design the new locomotive for increased efficiency, greater reliability, and lower maintenance requirements.
