With the explosion of international buses to Croatia, train lines are slowly dwindling away. Even on domestic routes, buses are much faster. The main advantages of train travel are for transporting bicycles which are not allowed on buses.
There are five daily trains which take about 2 1/2 hours. See the Ljubljana Train Station for schedules and booking.
There's one non-stop train daily from Vienna to Zagreb that takes about 6 1/2 hours and five other trains with one to four stops. Check schedules and book with GoEuro.
There's one non-stop train daily that takes about 5 1/2 hours and two more trains with stops in Salzburg. Check schedules and book with RailEurope.
There's one direct train daily that takes about eight hours and an overnight that takes about 15 hours.
Here are the major train lines :
Zagreb to Karlovac
There are over a dozen trains that run the 40-minute route. Two daily trains connect to Knin where it's possible to find a bus to Zadar but a Zagreb-Zadar bus is much faster.
Zagreb to Split
Again, the buses are much faster, taking about 4 1/2 hours to the train's 6 1/2 hours, but there are two daily trains--morning and afternoon that make the journey all year round. There's an extra couple of trains in summer, including an overnight train which can be convenient for arriving in Split early enough to take a ferry out to the islands.
Zagreb to Zadar
There are two trains daily both of which arrive in the morning. The late evening overnight train makes the most sense for an early arrival in Zadar.
Zagreb to Istria
There are no direct trains to Istria but the Rijeka train connects with a bus that winds through Istria stopping at Hum, Pazin, Zminj, Kafanar, Vodnjan and other little towns before ending in Pula about 4 1/2 hours later.
There are no trains to Dubrovnik or any trains that run along the coast.
All domestic train travel can be booked online at the Croatian Railways website or at any train station of course.
