Marble Control Panel Lever Switch Nov 23, 2006
Yeah, marble.
The station was designed to last 100 years and that was reflected in the materials selected. I'm used to seeing control rooms that look like this, so finding a marble-clad wall with old station controls mounted on it was a bit of a surprise.
Unfortunately I don't have any passable photos from the control room at the Toronto Power Company station but from what I remember, they were nothing like this.
This wasn't the first control room
The station operating controls were originally out in the main Power House on a mezzanine level above the bus breakers. (In the same open space as the large blue alternators.) At some point a new control room was built and everything was relocated there.
The following archival photo shows these controls back when they were on the mezzanine level.
