10th August Post Update.
There have been a number of questions about the turnback and the consultation process. The full details of the consultation are here:
On the same site there is comprehensive information about Dart+ Coastal North including an explanation of the Turnback north of Malahide Station. Irish Rail have now moved the full railway order application, details below in the link from the original post.

The Forum is delighted that Irish Rail engaged and listened to our feedback and have moved the Turnback from the Eastern Embankment to the Western Embankment North of Malahide Railway Station.
The original proposal would have led to an unnecessary and significant, permanent impact to local residents in the Marina and the movement of heavy machinery through the village during construction. Win, Win, Win.

Well done on turn back.
Need to get NISA to run its cables in the water from the turbines to Baldoyle. This would avoid digging up a lot of roads.
