running it is correct practice to balance the boiler pressure against the load being pulled and the track conditions. With a light load and level track the pressure may need to be only 25-30 p.s.i. therefore, turn the gas control down to keep this pressure. When running a heavy train with steep gradients, increase the pressure by turning up the

Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam. This means that even a small percentage blowdown can represent a high mass to be blown down. Water-tube boilers tend to operate at higher pressures, usually up to 150 bar g. The higher the pressure, the greater the energy contained in the blowdown water.
