Thanks for that article Branchline121. Currently there are 3 Enterprise sets along with spare coaches. A 200 metre FLIRT (or similar) would comprise about 10 carriages with a capacity of about 400+ passengers, similar to the current Enterprise sets. So 8 new sets should facilitate the proposed hourly service. The two big questions are whether the new units will be in service for the 2028 European Soccer Championships and whether a journey time of under 2 hours could be achieved once the DART is extended to Drogheda. I assume the planners in IR, NIR/Translink, the NTA, Dept of Transport, etc., are discussing these issues in the context of DART+ and the Strategic All-Island Rail Review. Hopefully some rational proposals will emerge later in the year.
