each solenoid-coil has united to it a bindingpost 3Q, to which is attached an electrical conductor 31, that leads tothe binding-post 29` of the next adjacent solenoid. The circuit is completed from the lastsolenoid to the source of electrical energy, such as the dynamo 8, by a return electrical conductor 32. It will be readily understood that the electrical current conducted to the various solenoids throughout the system is flashed instantly to the solenoids and that as a consequence all of the solenoids-are energized at the same moment, with the result that the controlling-valves 21 throughout the system' are all opened simultaneously and the brakes throughout' the system applied without `intermission at any point.
