Going to Ljubljana from Zagreb by train soon. The Seat61 describes the ride:
There are several trains every day linking Zagreb & Ljubljana, journey time 2h28. It's a lovely scenic train ride through the hills along the beautiful River Sava.
Is there a side of train that affords better views?
Some scenic routes I've been on in other contents are only scenic from one side as the train might follow the base of a cliff. Some passengers see a rock wall the whole way and others see valleys, rivers, towns, etc
