<p>Seattle's first railroad, the Seattle &amp; Walla Walla Railroad, was built to carry coal from the mines east of Lake Washington to the Seattle waterfront. The narrow-gauge railroad's first locomotive was named the "A.A. Denny" in honor of one Seattle's founders, Arthur A. Denny. In 1880, the railroad became the Columbia and Puget Sound Railway.
