DART passengers were forced to walk along the railway line last night after an electrical fault brought the train to a stop.
The company said the 6:40pm Howth to Bray service stopped just outside Shankill due to "overhead power line damage" on Wednesday.
It said the 40 passengers onboard were 'safely walked' 30 metres back to the platform by staff, after spending approximately one hour onboard the train.
The damage was repaired overnight and all services are now operating as normal.
Really worrying to read about this tonight. It is unacceptable & dangerous for passengers & staff, who had to walk from Shankill to Bray.
Irish Rail must carry out a full investigation so this does not happen again. Answers are urgently needed https://t.co/PE7n1fbqFs

Higher Education Minister Simon Harris posted on Twitter, calling for a full investigation to be carried out.
He described the incident as "unacceptable and dangerous".
Jane Creegan from Irish Rail said there was no safety issue.
"There was no danger at all, it was less than a minute's walk," she said.
"It was only 30 metres from Shankill which would be lit up.
"There was a number of Iarnrod Éireann staff there to assist those people.
"There was 40 people in total and they were all able-bodied and well able to walk the minute's walk.
"So, I wouldn't see there was any safety issue with it at all," she added.
