The control for the Anderbad Tunnel is approximately 14 miles from Anderbad, deep inside the mountain. From here, the monotrains' movement through the tunnel is monitored on a display screen, and in an emergency, the trains can be stopped from this control point.
In The Perils of Penelope, Doctor Godber used this control room (with the aid of his accomplice Roache) to stop the monotrain and kidnap Lady Penelope and Sir Jeremy Hodge.
He had also kidnapped Professor Borender the same way, a few days earlier. His aim was to force Sir Jeremy and Borender to reveal the secret process of their new rocket fuel.
A Lady in Peril[]
In a desperate attempt to get them to talk, he ties Lady Penelope to a ladder and lowers her into the path of the Anderbad Express.
Virgil and Gordon arrive at Anderbad in Thunderbird 2, meeting up with Parker in FAB 1. Realising that Lady Penelope has gone missing, Virgil and Gordon set off into the tunnel on the Monobrake. As the Anderbad Express approaches, the brothers discover Godber's hideout. A gunfight ensures, but the control panel in the sub-station is destroyed and the train cannot be stopped! Virgil shoots the ropes which holds Penelope in place and she falls out of the path of the train just as it comes hurtling through the tunnel.
