With a disable_item statement, it's possible to disable one or more existing items. This works for vehicles, houses, industries, cargos and airports. The general syntax is:

disable_item(feature[, first_id[, last_id]]);

feature specifies the feature of the item(s) to disable. If no further arguments are given, all default items of that feature are disabled. If one more argument (first_id) is given, only that ID is disabled. With two more arguments, all items from first_id up to and including last_id are disabled. For lists of default IDs, consult the documentation about that feature. An example:

 /* disable all monorail and maglev vehicles */
 disable_item(FEAT_TRAINS, 54, 115);
