Thumper

"It's called Thumper. Apparently, it helps collect the rock faster."

- Edward, Rusty and the Boulder, fifth season

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

Bio
Thumper was built by to 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. He often got out of control on mining sites and is now used for slate mining.

Persona
Although Thumper had no lines in his appearance, he has been said to act as a "cool man" and thinks that no job is too big for him.

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.

Livery
Thumper is painted orange with his name painted on his side of his bonnet in white.
