 my $lines_ar = $obj->get_lines;
 my $station = $obj->get_node_by_id($station_id);
 my $station = $obj->get_node_by_name($station_name);
 my $route = $obj->get_shortest_route($from, $to);
 my $stations_ar = $obj->get_stations($line);
 my $metro_name = $obj->name;
 my $xml_file = $obj->xml;

 # Pragmas.
 use strict;
 use warnings;

 # Modules.
 use Encode qw(decode_utf8 encode_utf8);
 use Map::Tube::Vienna;

 # Object.
 my $obj = Map::Tube::Vienna->new;

 # Get route.
 my $route = $obj->get_shortest_route(decode_utf8('Taborstraße'), decode_utf8('Kaisermühlen'));

 # Print out type.
 print "Route: ".encode_utf8($route)."\n";

 # Output:
