Dynamic brakes; Rheostatic brake; Blended braking (Rail); Blended brake; Rheostatic braking; Plugging mode; Hydrodynamic brake; Dynamic brake; Reostatic brake; Electrodynamic brake; Rheostat braking; Resistive brake; Hydro-Dynamic braking; Dynamic braking (locomotive)
  • [[Norfolk Southern]] 5348 diesel-electric locomotive employing dynamic braking. The cooling grill for the brake grid resistors is at the top center of the locomotive.
  • EMU]] at London [[Blackfriars station]] in 2006, which has been fitted with dynamic blended braking

Rheostat      
·noun A contrivance for adjusting or regulating the strength of electrical currents, operating usually by the intercalation of resistance which can be varied at will.
Rheostat      
An adjustable resistance; an apparatus for changing the resistance without opening the circuit. Its action may depend on the introduction of variable lengths of mercury column, of some other liquid, or of wire into a circuit. (See Rheostat, Wheatstone's.)
rheostat      
['ri:?stat]
¦ noun an electrical instrument used to control a current by varying the resistance.
Derivatives
rheostatic adjective
Origin
C19: from Gk rheos 'stream' + -stat.

Dynamic braking

Dynamic braking is the use of an electric traction motor as a generator when slowing a vehicle such as an electric or diesel-electric locomotive. It is termed "rheostatic" if the generated electrical power is dissipated as heat in brake grid resistors, and "regenerative" if the power is returned to the supply line. Dynamic braking reduces wear on friction-based braking components, and regeneration lowers net energy consumption. Dynamic braking may also be used on railcars with multiple units, light rail vehicles, electric trams, trolleybuses, and electric and hybrid electric automobiles.
