✦ Synopsis

Mr. Brecht explained that the difference between this locomotive and any predecessor is its use of Ignitron rectifier tubes to convert alternating current from overhead trolley lines to.direct current for driving its motors. While alternating current is easier and cheaper to transmit than direct current, d-c. driving motors have many operation and cost advantages. The Ignitron rectifier locomotive combines the advantages of both systems.

"With this new application of the Ignitron rectifier tube," Mr. Brecht told Railroad Club.members, "the locomotive is economical to operate, has a continual and unlimited source of power, is easy and relatively inexpensive to maintain, is easier starting, smoother riding, powerful at slow speeds, fast enough for any requirement--and pound for pound no other machine in the world can match it."

He said the 6000-hp., two-unit locomotive is 124 ft. long, on six motored axles. It weighs 740,900 lb. The locomotive's tractive effort, or ability to pull heavy loads, is measured at 189,000 lb.
