We were approx 20mins delayed at connolly. Funny announcement onboard (at malahide)stated that were stopping at portmarnock, howth junction and then nonstop to connolly... we then proceeded to stop at Kilbarrack

with a further announcment that it was non-stop from Kilbarrack to Connolly! I didn't see the broken dart as the train was like a cattlewagon by then.
