 =====Description=====
-The task of BBT is to ensure that locomotives / trains arrive as precisely as possible with the speed **V_min** at the **IN** detector. The locomotive is braking in a predetermined number of steps between **ENTER** and **IN**, as Rocrail sends decreasing speed commands to the locomotive at regular times. If the locomotive arrives at the **IN** detector after an attempt at a higher speed than **V_min**, Rocrail calculates a faster sequence of the steps and tries it with the next attempt. If the locomotive is at **V_min**, long before it arrives at the **IN** detector (and now creeps to the **IN** detector), then Rocrail calculates a slower sequence of steps. With each iteration, the sequence becomes more accurate to finally reach the **IN** detector with a point-to-point accuracy of **V_min**. In those cases, where the setting of the different speed steps between **ENTER** and **IN** is visually recognizable (i.e. jerking of the locomotive), you have the possibility to configure Rocrail in such a way that more steps can be used.
