Route redirection not working in Config?

Hi. I use multiple route configurations in Router.php. everything works except for "addRedirect()". Can't I use the "addRedirect()" method in the config file?
It dont works

PHP Code:

....
#$routes->get('/activate_success', 'Jobs::start'); 
$routes->get('/login/logout', 'Jobs::start'); 
$routes->addRedirect('site/datenschutz', 'Site::index/privacy');  
.....
$routes->get('/tags/(:segment)$', 'Jobs::index/tags/$1');
