There's a Wilhelm Tell Express train leaving Lugano at 11h33. The connecting boat from Flüelen to Lucerne will arrive in Lucerne at 16h47. Details, inluding a link to the timetables, are available at www.myswissalps.com/wi lhelmtellexpress. You'll have to leave early from Venezia St. Lucia to catch this train though, as this first leg to Lugano takes about 5 hours of traveling already. Luggage won't be a problem.
Alternatively, you can take any regular train from Lugano to Flüelen and get on a regular boat to Lucerne there, traveling the exact same route. In that case you won't be tied to specific times. You can plan this trip using the general timetable (www.myswissalps.com/ti metable) and the timetables for boats at Lake Lucerne (please follow the link under "More on other websites" at www.myswissalps.com/bo atlakelucerne).
Yet another option is to do the entire route by train, skipping the boat part. It's less diverse, but quicker and still scenic. You'd indeed travel via Arth-Goldau.
