3. Features

This set provides buses, trucks, small commercial vehicles, cars, horse carriages, and tractors, beginning from the year 1700.

• Small truck capacity is calculated using vehicle max load and cargo unit weight.
• Semi-trailer trucks and farm tractors can be refitted to single power units (using passenger refit).
• Running costs depend on truck and trailer weight (decreased without a trailer).

Refitting

• Refitting to a different truck body or trailer is expensive.
• For semi-trailer interchange, only a small fee is applied (difference between trailer purchase and sell price).
• Refitting without body/trailer change is free of charge.

Parameters

• Purchase cost modifier: Half, normal, and double purchase costs.
• Running cost modifier: Half, normal, and double running costs.
• Build cost modifier: Multiply or divide the road build costs from 1/16x of the default price all the way to 16x.
• Maintenance cost modifier: Multiply or divide the road maintenance costs from 1/16x of the default price all the way to 16x.
• Capacity multiplier modifier: Normal, double, or triple max load (use with caution if road slope is high).
• Keep old vehicles in purchase menu:
  Allows disabling expiration or extending the model life of old vehicles. This option applies only to this set. To disable expiration of all other vehicles, use the "Vehicles never expire" option in game settings.
