The basements of the barracks were often stone and brick, and many of them were connected by short tunnels.
Some small candles light one of the few surviving tunnels that once linked buildings on the campus with the steam plant. In winter, it was common for patients to be transported through these to avoid the cold, and during the Cold War these served as nuclear fallout shelters.

A colorful boiler is a happy boiler! RotoGrate systems remove ashes from the boiler firebox by revolving the bottom of the system to let the fly ash drop into a hopper. This greatly increases boiler efficiency.
