Questionable motor control

The locomotive continues even off the rails. Have seen in acquaintances, where the railways stopped immediately after derailment or deliberate positioning beside the tracks the set. We found this solution great because you did not have to catch the train again. Unfortunately, the engineers have these meaningful control amended so that the locomotive ever moves, independent of the underground. Only after 2 minutes will stop this. This change is justified by the fact that the train can be translated between different rail routes thus without a break. For us a significant step backwards.
