If Pantos fail to raise when Panto Up is pushed, what is the first action a driver should take?

The first action a driver should take when the pantograph fails to raise after the Panto Up button is pushed is to inspect the pantograph control and the pantograph motor MCBs (Miniature Circuit Breakers). This step is crucial because it allows the driver to verify whether there is an electrical fault or an issue with the control system that is preventing the pantograph from functioning properly.

By inspecting these components, the driver can determine if there's an immediate fault that can be rectified before taking further action. For example, MCBs may have tripped, indicating an electrical issue that needs to be addressed. If the control circuitry is not working correctly, this inspection may uncover the root cause of the problem, allowing for appropriate troubleshooting.

Taking this proactive step ensures that the situation is assessed properly and safely, adhering to protocols designed to maintain the integrity of the train's operations.
