Commissioning
Observe whether the wheels rub on the track,handle it in time to prevent damage once the phenomenon occurs.
Observe whether tilt,out of orbit or overturned after it sliding along the slope curve and colliding with another car.
Observe the runing codition on the minimum radius of curvature of the track.
