“It's called Thumper. Apparently, it helps collect the rock faster.”
Edward, Rusty and the Boulder, fifth season

Thumper is a quarry machine with two arms and caterpillar treads. He is used for loosening rocks.

Biography

Thomas & Friends

Thumper was built by the Sodor Mining Company and brought to the quarry to help clear rock, but his arms accidentally dislodged an enormous boulder which chased Rusty, Skarloey and Rheneas down the line before nearly crushing Percy and running into the sheds at the mine.

Because of his large size, he often gets out of control on mining sites and is now strictly used for slate mining.

Personality

Although Thumper never spoke, it has been said he's laid back in approach with a "cool dude" attitude, though he can come across as accident-prone.

Technical Details

Basis

Thumper is not based upon any known quarry machine - at any rate, a machine of his type would be extremely hazardous to those around due to the lack of a window at the front of the cab, making the operator unable to see. However, Thumper does appears to be a Hodge-podge of various different machinery. His front-end is from a GWR 0-4-0 Diesel shunter built by Fowler. His treads appear to be based off the treads of a Kliment Voroshilov tank, albeit with the treads mounted backwards with the drive sprocket in the rear.

In addition, assuming that a window would be technically where the face would be, such a machine would be impractical in real life as well due to the end of its arms not providing a sufficient amount of area to loosen the rock on the sides and below and above the machine, let alone be capable of making a proper hole through the cliff face and properly loosening or clearing rocks. The arms appear to be on a non-flexible joint with the siderods attached to the inner arms appearing to be quite thin, thus potentially leading to the machine being more capable of damaging itself than loosening or clearing rocks, unless being lightly placed in front of the rock / cliff face to properly function, which thus means that the rock may only be lightly loosened or cracked.

Livery

Thumper is painted orange-red with his name painted on the sides of his bonnet in white. His roof is painted black.
