Train Travel in Europe crossing 3 countries (Italy, Slovenia & Austria) - ÖBB EC 135 Trieste to Graz

This is a video of a trip on ÖBB EC 135 from Trieste Centrale to Graz. Filmed in the spring of 2023, the trip takes 6 hours and 30 minutes. After leaving Trieste Centrale, the train travels along the Karst Plateau and Gulf of Trieste before crossing the border into Slovenia. The train meanders through the Slovenian countryside including a stop in the capital Ljubljana and eventually crosses the border into Austria. I disembarked in Graz (unfortunately it was too dark by then to record) and the train continues onto Vienna.
It's a somewhat incomplete video. For example, I couldn't get any footage of the exterior of Trieste Centrale station or after the train crossed into Austria. But I hope you still enjoy it.
Thanks for watching!
