caption_attribution_description: English: UK Electric Multiple Unit Brake Handle, showing five positions; Release, Step 1, Step 2, Full service brake and Emergency brake
context_page_description: On trains, the expression emergency brake has several meanings:
  The maximum brake force available to the engine driver from the conventional braking system, usually operated by taking the brake handle to its furthest position, through a gate mechanism, or by pushing a separate plunger in the cab.
  A completely separate mechanism from the conventional braking system, designed to stop the train as quickly as possible.
  A handle or plunger which may be applied by a passenger in an emergency situation, either stopping the train directly or sending an alarm to the driver so that they can stop the train.
  The emergency brake applies considerably more braking force than the standard full-service brake. The engine driver or motorman will only use the emergency brake as a last resort, since it may cause damage; even with modern wheel slide protection, a train may develop wheel-flats, and the rails themselves can suffer profile damage.
