All the Zephyrs, from the Pioneer on, were diesel-electric.

>From "High-Speed Stainless-STeel Train Built for the Burlington" in
"Railway Mechanical Engineer" May, 1934:

"The power plant for driving the train, including power auxiliaries, was
designed by the Winton Engine Corporation, a subsidiary of the General
Motors Corporation.  Power for propulsion of the train originates in a
Winton high-compression, two-cycle, 8-in. by 10-in. eight-in-line Diesel
engine.  Power for all auxiliaries, wherhter driven directly or indirectly,
is taken from the engine inexcess of its rated output of 600 hp. at 750
r.p.m."

"The main generator is a single-beraing, differentially wound General
Electric machine plassced forward of teh enginer and directly connected
through a flexible steel-disc coupling.  A direct-connected exciter is
used.  A shaft extension is provided at the exciter end of teh main
generator to drive through V-belts a 25-k2. auxiliary generator mounted
above the main generator.  The opposite end fo the auxiliary generator
shaft is also extended for V-belt connections to the two fans which draw
air into the engine room."

"The two series-wound G. E. traction motors are mounted on the front truck
of the leading car.  They are self-ventilated by multiple fans mounted at
the pinion ends of the armatures.  Ventilating air is taken from the engine
room through canvas ducts, and motor ventilation is aided by the slight
positive air pressure--about 1 in. of water--in the engine room."

Best regards,

Randy
