Urgent Question about OBB Intercity Bus from Villach Hbf to Venezia

Hi,

I got a urgent question. I have a Eurail pass and I've checked my itinerary for my route from Budapest Keleti station to Venezia Santa Lucia station includes a bus trip on an OBB-Intercity Bus (number 835) that I have to take from Villach Hbf to Venezia Piazzale Roma. Is my Eurail pass valid for this particular bus? I know this question sounds silly as Eurail is supposed to be for trains and not buses but I was just wondering in this case whether it is part of the network? I can't find the information on the Eurail website and I have tried asking the railway people at the Budapest Keleti train station but they are not sure. I look forward to some quick assistance on this matter as I will be leaving tomorrow morning. Thanks.

According to this page on the Austrian Railways website,
> Eurail- and Interrailpasses will be accepted: supplement of 7,- Euro (2nd Cl.) or 9,- Euro (1st Cl.).

thanks alan1972 for the information!

The bus is just a substitute for the train, as the cooperation between the Austrian and the Italian railway companies on this track has been cancelled a few weeks ago.
