Abstract: A barrier vehicle system for an amusement race track is formed from a chain of pivotally coupled barrier modules. Each barrier module has a top and a bottom link separated by a spacer structurally joined with the top and bottom links to create a rigid structure when assembled. A pin extends through the top and bottom links, to one side of the spacer. An resilient, deformable barrel is journalled on the pin. To assist in attenuating high energy impacts, an extendable, energy-absorbing mechanism is attached to one end of the barrier, and the other end of the barrier is anchored to the ground.
