It's not uncommon to travel through Germany using only the regional trains. There are several tickets tailored to this, like the "Quer durch's Land Ticket", which is valid for a full day. I, for one, used to travel a lot through Germany using only the Wochenendticket, which is the predecessor of the "Quer durch's Land" - Ticket and was only valid on Saturday or Sunday.
