This 18 foot penstock section is being lowered downgrade to the dam from the fabrication plant at Electric City. Note this type of locomotive, a Shay, which featured reduction gearing, is particularly suited to steep grades, slow operations, and heavy loads. The round object on the top of the penstock segment is a manhole cover. These access points are still used inside the galleries of the dam. What will become the upriver side of the dam is seen in the background.
