Value for the rate of acceleration.
This is a default value; it will be used, if the acceleration parameter(s) in the timetable file are missing. If more than one vehicle in a train has this modifier, the value from the rightmost vehicle, which defines it, will be used. It is intended that only locomotives and rail cars carry this modifier - but Traffic itself does not know the type of the vehicle.
Traffic is not a train simulator. It is not intended to correctly simulate the dynamic behaviour of the trains. There is no way to control the acceleration or speed depending on the vehicles coupled to a locomotive.
