FIGURE 27. Transformer Station. Circa 1918.
Note: The Transformer Station (Building 77, 1918 - 1945) was designed as a two tier, multi-purpose
facility. The ground floor level was a building enclosed on three sides and sheltered by a hipped
roof providing an open-bay or garage effect. This enclosure was used as an automobile pit until 1945.
Extending from the hipped roof of the enclosure was a tower which contained a 2,300 volt transformer
station. On some Base maps, this structure was identified as a Sterilizer House.
