The drivers agree between them before they start as to how much work each will contribute to the overall effort. The train engine has its brake set to the running position and the ejector's small jet turned on, but other than that it takes no part in the braking of the train – the pilot engine has command of the brakes. The pilot engine's driver also has responsibility for sighting the signals, but the train engine crew will normally watch out and of course take any necessary action if the pilot driver misses one!
