 The brand was introduced on 16 May 1994 as 'Arrow', the first specific branding for diesel suburban services, with the launch of the Arrow brand on the newly opened Kildare line.This brand was applied to stations on the line, as well as the 2600 Class railcars.It was also applied to the 2700 Class and 2800 Class railcars upon their introduction (however in the case of the latter, it was removed shortly after their introduction into service and replaced with the National Development Plan logo).
