Severed Oxygen Valve Servo-Mechanism Cables
Three sheared cables—yellow, black, and green—lie coiled in the derelict control room’s corroded panel gash. Their ends are ‘bitten’ clean through where they once transmitted life-support signals, leaving raw copper cores exposed like broken arteries. The Doctor and Harry work frantically to splice the severed wires with a sonic screwdriver, their frayed insulation groaning under the Doctor’s weight as he manipulates the brittle filaments to bypass the breach.

Purpose
Life-support system control cables that originally transmitted servo commands to open oxygen valves, now severed to sabotage the station’s environmental regulation.
Significance
These cables are the literal pulse of the crisis—cut intentionally to trap the Doctor, Harry, and Sarah in a collapsing oxygen environment. Their repair restores not only air but also the team’s fragile hope, embodying the station’s violent past and their desperate fight for survival amidst deliberate sabotage.
