High-speed rail proposal In 2020 the Irish Government confirmed it will be launching a study into an approximately 500 km high-speed railway from Belfast via Dublin to Cork and Limerick, which could cost around €15 billion. Services In addition to the inter-city service between Belfast and Dublin, both NIR and IÉ operate local services along the route. NIR operates local services along the northern half of the line (see Belfast–Newry line) between Belfast and Lisburn, Portadown and Newry, while IE operates its Commuter services between Dublin and Dundalk as part of the Dublin Suburban Rail network. In addition, the line between Dublin Connolly and Malahide is electrified and forms part of the DART network. One early morning weekday IÉ Commuter stopping service also operates from Newry to Dublin Connolly and returns to Newry in the evening. The line is also used by rail passengers changing at Dublin Connolly onto the DART and also by connecting bus travelling to Dublin Port for the Irish Ferries or Stena Line to Holyhead and then by train along the North Wales Coast Line to London Euston and other destinations in England and Wales.
