THIRTEEN sticks of TNT found at Dublin's Connolly Station this morning could be up to 40 years old, gardaí have said.
Cross-border rail and DART services were affected after the train station was closed for several hours.
Workers found the explosives at about 11.30am.
The area was cordoned off and neighbouring houses and offices were evacuated while Irish army bomb disposal experts examined the explosives.
The station reopened after 2pm.
Iarnród Éireann confirmed the explosives were "historic in nature" and said normal services resumed yesterday afternoon.
The Irish army also dealt with a suspicious substance found in Dublin Airport yesterday morning.
A sample of the substance was removed for further examination.
The scene was declared safe at around 1.30pm.
