Permit grf-determined variable running costs
2.6 alpha 0 r1421 or later
Configuration file: variablerunningcosts on|off
Command line: -ZV
This switch will allow grf files to adjust the running costs of your vehicles. Other than reading the documentation, there is no simple way to determine if or how a grf may choose to adjust the running costs, beyond noticing that most grfs that want to adjust running costs will complain if this switch is off.
