At the time of its establishment Iarnród Éireann referred to itself as Irish Rail, and introduced the four rails IR logo; however, the initials "IR" (Irish Rail) were often defaced as "IRA" on signage.[citation needed] The company gradually brought the Irish form of its name to the fore, ultimately introducing its current IÉ corporate branding and logo in 1994. The Irish word iarnród (alternately rendered "bóthar iarainn") translates into English as iron road, or railway. While the name "Irish Rail" was dropped from the logo, it remains part of the official company name ("Iarnród Éireann - Irish Rail") and was revived as the name of the company's online booking service, irishrail.ie, in 2006.[citation needed]
