Yes, but with specific limitations. An Interrail Global Pass allows you to use your pass for two journeys in your country of residence: one "outbound" journey to leave your country and one "inbound" journey to return home. These journeys are intended to help you reach the border or an airport/port to start your international travels. You cannot use a One Country Pass for your own country, as the program is designed to encourage international tourism. During your outbound and inbound legs, you can make as many train transfers as necessary within a single travel day. If you live in a country with a large rail network like Germany or France, this is a great way to save on the expensive "last mile" to the border. Once you have used your one return trip home, any further domestic travel would require a standard local ticket, though you can still use your pass for travel in other European countries until it expires.
