Irish Rail is reportedly set to announce a €9m operating surplus for last year, its largest for five years.
Reports this morning said the figure represented a major turnaround for the company, which had a €92,000 surplus in 2003 and an operating deficit of €17.5m in 2002.
The reports also said Irish Rail was expecting to achieve an operating surplus of €15m for this year.
The improvement in the company's finances has been linked to improved cost control and a five-year programme of state investment that is now coming to an end.
