Accessing the Power Source

When you are standing in front of the SubWayne shutter, look for the red wire on your left. Follow this line down the stairs to find the work area.

You will need to switch to Catwoman to use her Whip on the yellow panel. This opens the black shutters and gives you access to the internal components.

Restoring Power

Switch back to Batman and interact with the red Toolbox to activate your X-Ray Vision. This view lets you see which green wires connect to the power grid. You must place two blue Batteries into the correct power stations to complete the circuit.

Insert the Batteries into the 2nd and 4th slots to restore the flow of power. Once the system is live, return to the SubWayne shutter and press the red button to open it for use.
