(*) Recent OpenTTD versions have added a number of base costs. To keep compatibility with earlier grfs, a number of 'old' base costs override the 'new' ones if the 'new' costs are not set separately. These cases are marked in the table. To avoid this behaviour always set the 'new' cost to 0 if you are changing the 'old' cost but want to keep the new one unchanged. Note that this may override other grfs that change base costs, but this is currently unavoidable.

(**) In TTDPatch and OpenTTD before r18268, setting these costs affects all vehicles. In OpenTTD after r18268, they apply only to vehicles defined by the grf, if said grf defines any vehicles of the related type itself. Else, they have an effect on all vehicles of the appropriate type.
