Possible complicating factor is that at about the same time Irish Rail started experimenting with radical new concepts like having trains that were not from the early 1960s, and having more than one commuter line in the entire country. So possibly hard to read too much into it; there’s an argument that Irish journeys just went up because the system was becoming rapidly less terrible.

(I remember being amazed as a kid in the 90s on encountering a mainline train that had automatic doors. Irish Rail was pretty behind the times for a long time.)
