Nickel Plate Road Steam Locomotive No. 587
Low speed: A standing Locomotive collects condensed water in its cylinder as trapped steam cools. Since it isn't
Compressible, this water can blow out a cylinder head when the engine starts.
To avoid this ,the engineer first opens valves called cylinder cocks under each end of the
cylinders(sometimes in the middle too ). Then when the engine starts,the exhaust steam comes
Whoooshing out of the cylinder cocks with the condensate instead of chugging up the stack.
Engines doing this spray steam from under their cylinder.
The starting steam cock open is controlled by CV147 (about =14) since steam loco has no drier.
