Examining more specific examples of rail freight, it is obvious that some of Iarnród Éireann's problems stem from the targeting of niche markets. Rail freight represents a segment of the goods transportation business, but the recent closure of IFI is likely to result in even greater losses for the company, especially when one considers that IFI accounted for 11% of total rail freight traffic with annual revenues of €3.5 million to €4 million. Such a development represents a substantial loss to it. The niche approach, therefore, is difficult to pursue in these circumstances because the company, which depends on only a few freight customers, is open to market vagaries.
