“…on which Mr Hazzard in purporting to be offended by a long-standing informational map would do well to reflect.”

Or, catch yourself on!  From the Belfast Telegraph, the operator of the national railway network in Ireland, Iarnród Éireann, with a demonstration of how to respond to contrived mischief-making by a member of the UK parliament, in this case Sinn Fein’s Chris Hazzard, MP.  From the Belfast Telegraph report 

A spokesman for Irish Rail said the company had worked “through good and bad times” to provide services between Northern Ireland and the Republic, including “the extraordinarily challenging era when sectarian entities repeatedly disrupted and threatened the service with violence”.

“The map in question has been used in some shape or form on our network for over a decade without any comment from customers (indeed the map shown in the tweet has our old logo so it’s probably over six years old, hence it’s a bit faded),” the spokesman said.

“The map is of the Iarnrod Eireann network but shows the Translink network also to show customers the Enterprise and connecting Translink services. The different colours merely clearly indicate to customers the IE and Translink networks.

“The Enterprise is jointly operated by Iarnrod Eireann and Translink, IE operate a morning and evening commuter service between Newry and Dublin, and all other services in Northern Ireland are operated by Translink.

“…Our commitment therefore to an all-Island and true cross border and cross community service with our friends and colleagues in Translink is unambiguous based on our record, on which Mr Hazzard in purporting to be offended by a long-standing informational map would do well to reflect.”
