Part of the way to keep costs low when building the railroad grade to Grand Coulee Dam was the use of mules for heavy grade leveling. Understand that when the contractor, Ryan Construction Company submitted a bid, they had in mind to do the work to the minimum standard at the lowest cost with the most profit to the company. Mules would fit this profile just fine.
