A Victoria Line (refurbished 1967 stock) train stopping with emergency braking as it often does to prevent overruns at station. Notice the horrible grunting noise at 15 seconds into the video, this is the emergency brakes being deployed, it is much louder in real life.
The Victoria Line train operation is fully automatic and the train speed is controlled by computers (ATO [Automatic train control]operation). For various reasons, the ATO can cause the train to overrun the stopping point and risk passing the monitors which the train operator relys on when closing the doors. Therfore if the train operator judges that the train speed is too great when nearing the stop marker, he/she will have to intervene.
In this video, the train operator only had the emergency brakes on momentarily. Sometimes the train is actually brought to a standstill whilst its still in emergency braking, and its VERY UNCOMFORTABLE. Hopefully the future 09 stock will have a better braking system.
