Correct Answer:
C. TPC with Section Controller.
Explanation:
A Power Block refers to the period during which the overhead traction power supply is disconnected to allow for safe maintenance or repair work on electrified railway lines. This operation is coordinated through the Traction Power Controller (TPC) in conjunction with the Section Controller to ensure that train movements are properly halted and the designated section is electrically isolated. This collaborative effort ensures that maintenance personnel can work safely without the risk of high-voltage electrocution while managing the impact on overall rail traffic.
