Mullardoch Dam & Power StationThe drawing below (click on the image for the high-resolution version) gives a good idea of the general arrangements at Mullardoch: Illustration: Mullardoch power station, general arrangementIllustration by: Photo of NOSHEB drawing by Mike Ross The surface structures of Mullardoch power station. The high building to the left surmounts the access shaft; from inside there a ladder can be descended to the power station. The I-beam is for the shaft hoist. The sunken structure to the left is primarily the winch house, but also contains lift which is the normal means of access, and the station batteries.

To the left from this point, a short passageway leads to the lift in the access shaft.

Shaft drops straight to the floor of the power station - it's around 100ft. Photo: Mullardoch power stationPhoto by: Mike Ross OK... back into the low building, into the lift, down the shaft. Lift doors open... we're in the small, simple main chamber of the power station. Local control panel to the right. On the extreme left, the horizontal-shaft generator, 2.4MW. Below floor level, accessed by the short ladder visible in the centre, is the top of the vertical-shaft Francis turbine. The deeply flanged & webbed blue object in the middle is a bloody great gearbox which turns the drive through 90 degrees.

The blue cabin to the right of the lift is for sound-deadening and contains a telephone; what with the turbine, the gearbox, and the generator, it's bloody noisy down there.
