Monitoring and control systems

A monitoring and control system comprising:

• a stationary body positioned along a path of movement;
• at least one sensor associated with said stationary body and configured to emit signals corresponding to a condition of said stationary body;
• a moving body that moves along the path of movement and physically interacts with said stationary body during movement along the path of movement;
• at least one sensor associated with said moving body and configured to emit signals corresponding to a condition of said moving body;
• at least one computing device, having one or more processors and located either on said stationary body or on said moving body or remotely, configured to receive and possibly process signals from said at least one sensor associated with said stationary body and to receive and possibly process signals from said at least one sensor associated with said moving body;
• wherein said at least one computing device is also configured to determine a performance value of at least one of said stationary body and said moving body based on the physical interaction between said moving and stationary bodies as said moving body traverses said stationary body during travel along the path of movement;
• and
• wherein said performance value is dependent on both of the signals received from the at least one sensor associated with the stationary body and the signals received from the at least one sensor associated with the moving body during the period that the moving body physically interacts with the stationary body.
