I'd really like to see an Irish route. Maybe east to west line, Dublin to Galway or Limerick. Will never happen but may as well suggest it
Never say never, but I think you should make a proper suggestion, with images and descriptions. I think that attracts a lot of attention from the community. I would personally love an Irish route, but they're only going to make one if a lot of people want it, due to money and time restrictions. So if just 2 people want a route, it's not gonna happen.
Just to add, Sam went through the top 50 requested routes on last night's stream and Ireland didn't make it. It was around 70th place.
It would probably end up being Dublin Suburban, maybe part of the Rosslare Line to give the service frequency, though Belfast to Dublin would be an interesting study.
