The Old Faithful Inn was commissioned in 1902 by Child, and funded with loans from the Northern Pacific Railway, using laborers who were experienced railroad trestle builders.
 Child introduced Reamer to Charles Sanger Mellen, president of the Northern Pacific.
 
While he was carrying out design work on the Old Faithful Inn for Child, Reamer was also designing the Gardiner, Montana depot for the Northern Pacific, at the northern entrance to Yellowstone National Park.
 The depot and the Inn were complementary projects, and similar in style.
 The depot opened first, in 1903, and embodied many design features that Reamer explored on a grander scale at the Old Faithful Inn.
