Control mechanism for a rail system, rail system provided with such a mechanism and rail vehicle provided with such a system

A control mechanism configured to equip a rail system and to act mechanically on mechanical members of the rail system, the control mechanism comprising:

• a casing from which at least one control rod projects, and wherein the casing is configured to mechanically and securely connected to at least one control cable actuatable at a distance from or in proximity to the casing;
• a plate mechanically connected to the casing by at least one attachment member and from which the at least one control rod projects;
• and
• a locking/unlocking device positioned in a recess provided in the plate and having a stable position, wherein the control mechanism is configured so that, when the at least one control cable is mechanically connected to the at least one control rod, the locking/unlocking device is elastically moved away from its stable position to allow the partial introduction of the at least one control cable in the plate as far as a position in which the at least one control cable is mechanically and securely connected to the at least one control rod.
