“If we can cach, at the Hutt Valley Workshops, save five minutes per day—I do not mean force the men along, there are other ways to do it—a sum of £6,000 to £7,000 would be saved in the course of a year in this workshop alone. Imagine what that saving would be if a similar result could be achieved throughout the service.”—Mr. A. E. P. Walworth, Manager, Railway Workshops, Hutt Valley.
This translation of time into terms of money saved occurred in the speech of the Works Manager, Mr. A. E. P. Walworth, at the first reunion of officers associated with the Petone and Hutt Valley Railway Workshops.
Referring to what Mr. Walworth had said about organisation, Mr. H. H. Sterling (General Manager) said it was a good sign that so many were found to be thinking along the same lines. The old order was changing.
Among the changes was the coming of motor competition.
