How is the Traction Challenge carried out on the competition weekend? How is the Traction Challenge result averaged? If it’s over a certain distance, can you confirm the distance the measurement takes place?
The Traction Challenge will be run in accordance with the rules. The positions of the points will be indicated on a plan of the railway and provided to all teams in due course.
The distance between points F and G used for the traction challenge (in combination with the noise challenge) will provisionally be approximately 100m up the gradient between the
Haven and the tunnel.
Averaging of the acceleration: this will be measured using a vibration meter which takes successive one second average measurement for the duration of the test run.
