Express Mail. 
Express service was available on paymen of tthe Express Fee that was identical for both inland and foreign mail, except for a short period from April 1, 1981, to February 24, 1985, when there was a differential. On January 20, 1992, the Express service was abolished and replaced by Swiftpost, a trackable priority mail service that spans both the foreign and European Community postal rates: £2.00 for all international mail, inc. Great Britain (£1.00 – inland inc. Northern Ireland).
While the Express Fee only guaranteed Express service within Ireland to the point of departure (usually the Central Sorting Office, Dublin), destination countries often gave such mail their equivalent service, and sometimes applied their own cachets. Ireland, along with Great Britain applied vertical blue lines to the front and back on Express Mail items, but the large design Express label ‘M.P. 459’, initially a pink colour and later changed to red, seems makes the blue lines seem superfluous. Other countries do not apply this distinctive feature.
