The cog, or rack and pinion, system that allows the locomotive to climb Mount Washington. Located in the museum. The rack rail design used is one of Marsh's own inventions, using a ladder-like rack with open bar rungs engaged by the teeth of the cog wheel. This system allows snow and debris to fall through the rack, rather than lodging in it. [42]
The Pilatus Railway is the steepest rack railway in the world, with a maximum gradient of 48% and an average gradient of 35%. Functioning of the rack and pinion on the Strub system. A rack railway (also rack-and-pinion railway, cog railway, or cogwheel railway) is a steep grade railway with a toothed rack rail, usually between the running rails.
A rack and pinion has roughly the same purpose as a worm gear with a rack replacing the gear, in that both convert torque to linear force. However the rack and pinion generally provides higher linear speed — since a full turn of the pinion displaces the rack by an amount equal to the pinion's pitch circle whereas a full rotation of the worm screw only displaces the rack by one tooth width.
The water is drained at the bottom, and the process repeats with the cars exchanging roles. The movement is controlled by a brakeman using the brake handle of the rack and pinion system engaged with the rack mounted between the rails.
