There were brief delays to DART services through Dalkey and Glenageary this morning due to deer appearing on the line and platforms.
Iarnród Éireann staff responded to try to move the deer to safety.
However, the deer then left the area by itself.
The deer had also appeared in the area at about 6pm yesterday evening.
While normal service has resumed, Iarnród Éireann drivers are taking extra caution in the area.
The young deer is still on the southbound platform in Glenageary station. Looks very disoriented. pic.twitter.com/txEp3H08D9— Ronan O'Keeffe (@ASportingView) May 10, 2019
