Traction/Brake Lever

Lever(s) used by the driver to drive the train. It may be composed by one or more levers (e.g. traction lever, EDB lever, pneumatic brake lever, etc) but from the ATO-OB functional point of view it has only three different positions: a)        Traction: when it is requesting the rolling stock to traction; b)        Neutral: when it is requesting the rolling stock neither to traction nor braking; c)        Braking: when it is requesting the rolling stock to brake.
