OUR model locomotives rely on kinetic energy from flywheels to overcome minor interruptions in electrical supply from the rails. The booster devices designed by Alfred Raworth for the Bulleid ‘Booster’ locomotives worked in a similar way to mitigate gaps in the conductor rail. Granted, we do not have miniature motor generator sets incorporated in our models, but the use of flywheels to smooth out model operation is an accepted technology today.
The boosters, in what became designated as Class 70 electric locomotives, served several purposes, the primary one was to assist the locomotive over gaps in the conductor rail and to smooth out operation where gaps occur, thus avoiding snatching of couplings.
A booster is a motor generator set with a large one-tonne flywheel
