Slow bus to nowhere

I'd looked this bus up online and it looked like the only one available. I still think that's the case but unfortunately we're visiting the non-tourist cave, Skocian. Another cave, a little closer to Ljubljana, has better and fast connections. This one has only the local bus. The distance is about 60km and there is a motorway, but every 10km the bus took a detour of 15 minutes to visit local towns on route. It meant to journey was 1 hour 40 minutes. I knew the from the timetable bus thought it was because the caves were far away. In fact Ljubljana is a very small country, half the size of Wales, but everything is far because of mountains and slow connections. At least we were treated to a old locomotive at each stop. I think an important railway was built through here connecting to Trieste.
