A number of loader cars for carrying escapees or properties from each exit tunnel along the track to escape, each car having four universal wheels underneath the bottom of the car and two parallel axles perpendicularly fixed at the upper and the lower end back side of the car, a set of several ball bearing rollers connected each other by specially curved springs is rotatorily mounted on each axle for supporting and traveling along the tracks. A group of special contour retaining bars pivotly mounted between the parallel plates of the track for automatic sequence control of the traveling cars. A spring damper located at each turning point or corner of the track for dampening the speed of the traveling car.
