I am interested to know how water was delivered into a boiler for a stationary steam engine such as in the O scale sawmill.
Was water gravity fed from a tank or pumped in by hand from a nearby water container??
And if it was gravity fed from a tank how was the tank filled ??
I have found some information on steam donkeys water supply but it also not clear how the water gets into the boiler.
Any pictures or drawings would be good.
Thanks in advance.
