In the locomotives editor you manage the data of the locomotives on the railway:

In the top list you enter all the data of your locomotives.

The speed profile section is very important. You should create the speed profile for each locomotive by measuring. Most of that is done automatically by the software. You need a (preferably straight) track section for measuring with three sensors, like this:

----|----A----|-------------------B---------------------|----C----|---

The orientation must be so that the locomotive drives towards sensor B when located in sensor A and driving forward. And there must be plenty of track left before sensor A and after sensor C.

The three sensors must be put into the three drop-down boxes in the "Measuring track sensors" group in the order A, B, C. The length of section B in cm must be entered into the field to the right of those boxes.

To measure a speed profile, place the selected locomotive in sensor A and press the "Measure profile" button. The program will then drive the locomotive back and forth and measure the speed at all different speed steps.

You should also measure the stopping distance of each locomotive for at least three speed steps, e.g. minimum, 6 and 12. You can best do this after measuring the speed profile by selecting the desired speed step in the list and pressing the "Measure stopping distance" button. The program will then drive the locomotive towards sensor B and set its speed to 0 when reaching sensor B. Then you measure the distance from the start of sensor B to the point of the locomotive that first touched sensor B (i.e. the first or last wheel, depending on the direction) and enter that distance in cm into the "Stopping distance" column for that speed step.
