The mole

A high-speed, manned 30 ton tunnelling machine capable of boring through even the hardest rock to rescue individuals trapped underground. A serial number of "56156" can be seen on the top rear port side of the Mole. Due to an inbuilt thermal-imaging system in its drill bit, the Mole can be operated with acute precision to ensure that buried individuals are not endangered from rockfalls caused by drill movement despite the fact that the drill screw rotates in the wrong direction. The Mole is carried to rescue sites on its trolley, then tilts to commence drilling. Caterpillar tracks on both sides enable it to return to the surface.[1] The vehicle is often carried in Pod 5, and is notable for being one of the few pod vehicles to appear in multiple episodes; it also appears in the closing credit sequence with the five main Thunderbirds machines and FAB1. It appears in "Pit of Peril", "City of Fire" and "The Duchess Assignment", and is glimpsed in the pod vehicle bay in "Cry Wolf". It is generally regarded as one of the most popular machines of them all and barring Thunderbird 4, has had more replicas made than any other pod vehicle.
