'Purging', not a word I associate with steam locomotives, but do associate with removing contaminants from the fuel cells used on the Apollo and Space Shuttle programmes.
Cylinder drain cocks tend to be at the front of a locomotive because that's where the cylinders are located, at least on a conventional locomotive as distinct from an articulated design or a Shay, and the boiler blowdown is at the back because that is where the firebox is located (again, on a conventional locomotive).
That blowdown valve terrifies me - if the linkage fails with the valve open there must be a real risk of emptying the boiler with disastrous consequences!
