The digging was done by huge tunnel boring machines, known as TBMs, which cut through the chalk, collected the debris, and transported the debris behind it using conveyor belts. Then this debris, known as spoil, would be hauled up to the surface via railroad wagons (British side) or mixed with water and pumped out through a pipeline (French side).A tunnel digging apparatus (10) has an undercarriage (12) pivotally attached to a moving means, the undercarriage (12) being pivotable between a first moving position where the machine may be moved over a surface (44) by operation of the moving means (34) and a second operating position such that at least a portion of the undercarriage (12) is in contact with the surface (44).
