What should you do upon occurrence of an excessive wheel slip (Spinning) during start-up?

Explanation

Correct answer: Reduce the intensity of the tram's acceleration.

Wheelspin, or excessive wheel slip, occurs when the tractive force is too great in relation to the adhesion of the wheels to the rails. To regain the lost adhesion, the tractive force must be reduced by decreasing the rate of acceleration. This action will allow the wheels to regain contact with the rail and ensure the tram moves off smoothly and effectively.
