Can anyone tell me what is the difference between the driver commands 'drive to' and 'navigate to'? I assume they must be different or otherwise why have both.
The main difference is how things are handled if there is another train in the way when the train you give the command to reaches such an area. With Drive To, the train will not try and find an alternative route around the affected train if one is available, whereas with Navigate To it will.
I believe that drive to simply takes the shortest possible route whilst navigate to is more intelligent and tries to take a route which avoids other trains etc.
