If you were searching for a connection on DB's website, it doesn't show it for some reason. Try just Sezana-Ljubljana and you'll find it 1 minute after the train arrives from Villa Opicina to Sežana. (however, there's no connecting train for Nova Gorica)The Slovenian railways have started running trains again to Villa Opicina in Italy. This is good news, but what I don't understand is the schedule. The trains don't connect in Sezana with the trains from Ljubljana, which is quite puzzling. Is there a particular reason for this? As it is now these trains are not very usefull.
I found out that it's a glitch in the on line time table. I've done some research and found out what is going on.^^ Don't know but i have another question about that. You know if there are directly connections from italy to lubjana?
That's right. On Ljubljana-Sežana you take a Desiro, on Sežana-Opicina there's a locomotive and a carriage. See this post.However, the rolling stock SZ uses on Ljubljana - Sezana can't enter Italy any more. (It could in the past...). Do for the Sezana - Villa Opicina part they use a different train, and everyone transfers in Sezana.
