Monobrake

A low-slung search and recovery utility vehicle capable of either travelling along monorail tunnels or, by using its front mounted telescopic arm, can be attached to an overhead monorail line for greater speed. Due to its low height, the Monobrake can remain in a monorail tunnel and have a train pass over it without incident. The vehicle has seating for two people. The Monobrake appeared in use in the episode "The Perils of Penelope", is glimpsed in the vehicle hangar in "Cry Wolf" and can be seen in Pod 1 in "Security Hazard". Both Konami and Bandai produced models of the vehicle.
