What is the final step to attempt raising the pantographs after performing previous actions?

The final step to attempt raising the pantographs involves pressing the raise pantographs button. This button is designed as a direct command to initiate the pantograph raising mechanism. Prior to this step, specific preparatory actions are typically taken to ensure that the pantographs can be raised safely and effectively. These actions might involve checking the power supply to ensure that the system is operational and verifying that the train's systems are ready for the pantographs to be activated.

By pressing the raise pantographs button, the operator communicates the intention to engage the raising mechanism, which is crucial for the pantographs to function correctly. If previous checks have confirmed that everything is in order, this button can then safely engage the raising process. Thus, this action is essential as it initiates the movement needed for the pantographs to connect to the overhead wire, facilitating the transfer of power to the train.
