 The lower byte (rr) contains the (translated) railtype/roadtype/tramtype the vehicle is currently driving on.
 If the railtype/roadtype/tramtype has no entry in the railtype/roadtype/tramtype translation table of the GRF, this value will be 0xFF.
 If no translation table is present, the raw value will be returned.
