Wouldnt the blow down valve being open mean there is no water in the boiler as it is warming up? Or how does that work?
Different railroads have different ways of lighting fires, but the main thing is to maintain water level as pressure builds. I understand having the water at 1" instead of half a glass because theres less water to heat up, but theres not much room for cushion should an injector not work properly.
