One of the emergency alarms located adjacent to the external doors on the mockup of the London Underground 2009 stock that will replace the existing 1967 stock on the Victoria Line. When the alarm button is pushed an alarm sounds in the driver's cab and the "Driver Aware" indication is given to the passenger. Once the driver has acknowledged the alarm the "Speak to Driver" indication is given so the passenger can communicate the nature of the emergency to the driver who can take the apropriate action.
