PRESIDENT WARREN G. HARDING and his wife paused at the Continental Divide on Jul. 2, 1923, while on the trip through the U.S. and to Alaska which ended with his death a month after this picture. An electric passenger locomotive pulled his train through this electrified operation area. Electrified operation is used on 656 miles of track, the largest such operation in the U.S. today. Electric freight locomotives of this general type are still in use.
