deadman's brake en · NOUN
Meanings
-
A brake that normally operates under pressure, but engages fully when all pressure is released.
Two rates of deadman's brake application are provided on the locomotive to suit the class of train being hauled. Selection is by the Braked/Unbraked changeover switch. This does not affect driver-controlled braking, but allows a slower rate of application of the deadman's brake when hauling unbraked stock.
