I've been hearing about BIRG tickets and checked ftroute's website regarding them. I read that they are not train tickets but transportation tickets sold by ATAC and COTRAL.
I guess I'm confused since I thought I could use these tickets to take the train from Civitavecchia station to Rome Termini station?
Also, the BIRG tickets are only good for Regional (2nd Class) trains correct? So I could only take a Regional train from Civitavecchia to Rome? Can I purchase BIRG tickets in advance?
One last question, I read that I can purchase them at the ticket office, but I wanted to avoid any huge lines at the train station to purchase these tickets. Are they available at other locations near the train station?
Thanks for your help.
