What do you think the devs will do when they run out of headcode letters for new termini? (Reply in comments)

We all know that there will be a station after James Street in the future. But we don't know what the station name is or what it looks like. I think James Street will be a through and terminus station just like Newry. 2 platforms could be for terminating and 2 platforms could be for trains going to the next station. I also think that the entrance/exit will be upgraded (most likely it will). Tell me what you think
