Train Ticket
From FOnline: Aftertimes
This ticket is required for traveling from one train station to another. You can purchase tickets for 100 caps each at any of the four train stations and a single ticket is spent in dialogue when you get on the train. You can purchase as many tickets as you can afford to buy. Train tickets are generic so any ticket can be used by any character, unlike Vault City Day Passes which are tied exclusively to whichever character was granted the pass at Vault City.
