A route that I have travelled a few times. It runs from Malahide and Howth to the north of Dublin down the East cost of Ireland through Dublin to Bray and Greystones in County Wicklow. There are lots of stations and a very regular service with lots of views of the Irish Sea. The full route from Howth to Greystones may be too long for TSW2 so maybe Dublin to Greystones. There are also diesel commuter express trains that go further that run this route to add an alternative. It would be good as a first Irish sim for TSW2.
