Hi everyone,

I am planning to travel from Ljubljana to Zagreb on Friday the 6th of August, 2021, but I am not sure if there is a connection between these two. 

In the web-version of the Interrail rail-planner app I find plenty of possibilities: https://bit.ly/3qP4Ba8

But when I check the same search request on other reliable websites for European trains I find no results at all apart from taking the Flixbus:

• Results on Trainline: https://bit.ly/3AseDCF
• Results on RailEurope: https://bit.ly/3hG30j1

However while writing this question I noticed that NS International suddenly showed results that overlap with those shown on the interrail rail-planner app, which wasn’t the case a few days ago: https://bit.ly/3ypRijb

Then I also checked the websites of the official railway organizations in both Croatia and Slovenia, which both said there is indeed a connection between Ljubljana and Zagreb but on the Croatian website (https://bit.ly/36c0jAb) there are four departure times a day that all overlap with those shown on the interrail website, while on the Slovenian website (https://bit.ly/3hF1RYO) there are only two departure times a day of which only one overlaps with the ones shown on the interrail and Croatian websites, which is at 14:45 pm.

So this leaves me with only one departure time that is recognized by most sources, but not shown on Trainline and RailEurope, which still makes me doubt if it is actually operating, and a bunch of other departure times of which it is not clear at all whether they are operating because all sources are contradicting each other. 

Long story short, is there anyone who knows more about the train connections between Ljubljana and Zagreb who can tell me if there are trains operating between these two cities at all and if yes, at what times? 

Thanks in advance!
