Butterfly Canopy
The passenger shelter along tracks 1 and 2 is the only remaining canopy of a series of five. The other four canopies were demolished in April 1969. It was built in 1928 to Southern Pacific plans and is similar to canopies at the Sacramento Station in California, and is 23 feet wide. During the peak of passenger train travel in 1927, a tunnel was built under the eleven tracks with stairways to the surface at each platform. Called the passenger subway, this tunnel allowed pedestrians to access all eleven tracks from the Grand Lobby, bypassing those tracks that were occupied by trains. When passenger service ended the tunnel was filled in for safety purposes, although when the platform was repaved in 2008 a portion of the tunnel was uncovered. Plans are to place a glass over the uncovered portion for visitors to see.
The Butterfly Canopy and platforms are host to Union Pacific's Steam Team during their East-West trips over the Transcontinental Railroad route and the former Rio Grande Soldier Summit route. The operating water column at the north end, which is connected to the Ogden City water line, allows the steam locomotives to be serviced conveniently.
