These valves too are interesting and surprising.
These handwheels are connected by linkages to turbine drain valves below. Newer stations have motorized valves operated from the control rooms or by computer. They still have to be checked by an operator to make sure they worked properly. The Hearn station had very few
automated valves. It was run buy hand. There were never even any computers in the computers in the control rooms. A lot of people liked it that way. There was a saying at the station "automagical - autotragical".
