Train connections & reservations

Hi Everyone, I am planning a trip with my girlfriend and we wanted to travel from eastern europe to Greece or Turkey. But when we use the Interrail app we dont see any options. Doe someone has a solution for us? Or is someone planning a trip in the same direction? 

I want to make a reservation with interrail and also one without for someone else not having  interrail to travel together. How can I do that?Thanx 

Hi everyone! I am quite new here and also in Eurail. What is the train I have to take from Rome to Naples? And... where it is located?

Hey I have a question. When I travel on trains where reservations are not obligatory, do I just have to get on and show the Interrail ticket on my mobile phone? Or do I have to buy a 0 Euro ticket somehow beforehand?

HelloI want to travel to Spain this summer. I took a Global Interail Pass.I am unable to book seats on domestic lines:barcelona -valencevalence -madridmadrid - barcelonaeven on the smartphone application.Maybe there is no need to make a reservation, but then does that mean I can travel free of charge and just with the pass?Do you know of a help number that I can reach?Thank you all for your help 

What is the least expensive method of making a train reservation?

Hi! This summer me and my friends are going to Italy, we already have our interrail pass ‘one country-italy’ but we can’t find if the pass includes a ferry in amalfi coast to capri. Anybody knows? I’m sorry for mt english 😅 

I am currently planning my trips and would like to know which trains require extra seat reservations.
