Translations:Cutoff/2/en

With the regulator open, the vehicle’s chest is fed steam at a relatively constant rate from the boiler. However, the chest’s exhaustion rate to the cylinders increases with the vehicle’s speed, because the cylinder cycle becomes more frequent. At a certain speed, with the cutoff set to full forward, the chest no longer receives enough steam to overcome the exhaustion and the vehicle stops accelerating. However, by gradually pulling back on the cutoff the faster the vehicle goes, the driver is able to give the chest increasingly more time to pressurize, making it possible to reach greater pressures and speeds.
