- New Power for the Zephyr Power Car -- Removing the #2 Cummins Engine with Generator
Our Volunteers in Action
It takes a lot of work, time, energy, elbow grease, dedication, and determination to keep our Museum in Motion.
We've assembled these photo essays, to share with you some of these activities.
[Please be patient while the graphics load; we hope you'll find their detail worth any delay.]
The Power Car Venus (CB&Q 960) of the Nebraska Zephyr has three diesel engines with attached generators, which provide power for the train. Each is mounted crosswise in the front compartment of the car. With the two roof covers and the #3 unit removed, the #2 unit would be removed. Each engine weighs approximately 2,250 pounds and has an attached generator of similar weight, about 4,500 pounds total.
(photo above) Dave Dote (left) and Matt Rumpfeldt work to nudge the #2 Cummins engine off its mount, with help from the crane, as Wes Lloyd observes.
(photo above) It will take several tries before the engine and generator are clear of all of the mounting bolt studs. Dave Dote and Matt Rumpfeldt prepare for the next attempt, with Dave Schroder, Wes Lloyd and Martin Kocanda. The #3 engine was removed from where Dave is standing.

(photo to right) Things don't always work as one would like! This bracket at the end of the #2 Cummins engine, snapped with a resounding noise as the engine was being raised.
There is often more than one way to get the job done. With an additional chain being added to the rigging, it takes the load from the cracked bracket, and hoisting resumes.
(photo above) After several tries, the engine is free of its mounting bolts, and can begin its ascent. Dave Dote (left) guides it as we prepare to lift and swing it 90 degrees and up through the roof. Martin Kocanda, Wes Lloyd, and Harold Driscoll are ready to lend a hand as it rises.
(photo above) Persistance pays off, as Dave Dote (left) guides the end of the #2 Cummings engine, and Harold Driscoll (right) guides the attached generator. As soon as it is lifted enough to clear the electrical cabinets on either side of the generator, it will be rotated and hoisted through the roof opening.
Looking toward the front of the Venus, in the foreground are the electrical cabinets for the steam generator on the left and for the #3 generator (previously removed) on the right. Wes Lloyd and Dave Schroder are ready to assist with the rotation.
(photo to right) The engine and generator have cleared the roof of the Venus as Jamie Kolanowski keeps a steady hand to guide its descent.

(photo below) Max Tyms (right) guides the crane with his gentle touch as the #2 unit is lowered toward the ground. Wes Lloyd stands ready (right).
The #3 engine is in the foreground, with its generator to the right beyond the picture.
(photo above) Wes Lloyd (left foreground) and Dave Schroder guide the engine and generator to the ground under the control of Max Tyms. The two roof hatch covers can be seen in the foreground, and the #3 engine and generator are on the ground behind Dave.

(photo above) Martin Kocanda checks over the #2 engine (our left) and #3 engine. The engines and generators were then moved via forklift and covered with blue tarps, awaiting transport to the engine repair shop for rebuilding.
The project went so smoothly that a few hours of daylight remained. Several team members made good use of the time, swapping out the #2 Governor from EMD E9-A locomotive BN-3 with a replacement unit.
