Hi,

This might seem like a silly question, but when you operate the horivontal water injector is it best to turn the steam or water on first. Or does it not matter.

Essential to turn the water on first to keep thigs cool. The way it works relies on the steam condensing in the cold water and you also need to be able to adjust the steam flow to get that to happen smoothly. You often see drivers looking over the side of the loco to see the injector is first dribbling water, then ‘picking up’ and not disappearing in a cloud of steam.
