designed to pull a heavily-loade- d freight train up mountains and down mountains around eurves and over straight stretches fester easier more efficiently and more economically than any freight engine yet constructed This' new locomotive is a monster of the rails With a rating of it measures 193 feet front coupler to coupler and weighs 484 tons diesel engines Operated by four its generators feed electric current to 16 traction motors located in the trucks and geared to 16 driving axles applying power to tho rail at 82 points or at oach of tho 32 wheels The locomotive composed of four sections coupled together carries 4800 gallons of fuel oil enough to handle a 100-ctrain weighing 1000 tons 500 miles on a level track without flopping Tho diesel principle the explosion of combustible fuel ignited by beat generated by compressing pure air in the engine cylinder is new in railroad locomotion Less than 10 years ago tho diesel engine was something vague to moat of us on unknown quantity At that timo they were ponderous machines most of them solidly mounted only a few haring wheels placed under them But during this pait decode railroad engineers found the diesel principle applicable "with the result that several railroads installed passenger trains on regular runs speeding up the time' schedules on whteh traina had been operating between the lews points New the power and speed of the diesel locomotive have been put to uso in tho gruelling transcontinental freight rune Perched In the cab with tho engineer this writer recently rode this giant of the rails on the world's first diesel freight distance run— from Chicago to Los Angeles on the Atchison Topeka and Santa Fe Railway the first railroad to inaugurate regular diesel freight service —to find out what use a diesel
