I have booked train Ljubiana to Budapest Nygati.The train only travels to Kelenfold and i have to get public transport how does this work
There are no direct trains from Ljubljana to Budapest-Nyugati, so I doubt you have a reservation until Nyugati.
From Kelenföld to Nyugati, you can take the metro: M4, change to M3 at Kálvin tér.
In terms of your pass . . . it doesn’t cover the metro, so you will have to buy a ticket to get between the stations.
If I understand your question correctly, you arrive at Kelenfold, get off your train, head towards the metro station, buy a single ticket and get the metro to Nyugati..
