With this dialog, you determine the real speed of a model train. For the determination, you need to measure a part of your track. Enter the value in the field "Distance". Select a part, where you see the start and end point. The longer the distance is, the more exactly becomes the measurement. For the conversion on the real speed, you must enter the scale in the field "Gauge".

Then you start the test train. As soon as it reaches the beginning of the test track, press "Start". Now the time is running. The other values make now no sense. As soon as the train passes the end point, press "Stop".

Under the time, you see the speed of the model, as it moved on the track. On the right side, this speed was converted to the speed of the original. In most cases this speed is for a visitor to slow. Therefore, the standards of European model railways 661 define for every gauge size a correction factor. In the field "Correction" you see the speed, how viewers of the model train would feel the speed.
