The ash bin is directly across the street from the boiler roomand ashes are delivered to it through a bridge by means of a telpher-age system which hoists and transports the ash cars from the boilerroom basement up to the level of this bridge and thence across intothe tower where the contents are dumped into the bin.

All the steel workinside and outside is covered either by brickwork or by reinforced!concrete. The roof of the ash bin is composed of reinforced con-crete slabs, similar to the roof construction of the power station. The General Features of the Power Station Equipment.
