context_page_description: The Dublin–Belfast corridor is a term used to loosely describe a geographical area that encompasses the two capital cities of Dublin and Belfast, the smaller cities of Lisburn and Newry, and the area between that includes other major towns such as Drogheda and Dundalk. The term has been used in papers regarding planning strategies in the area, with the aim of capitalising on the expanding economies of both cities.
context_section_description: The main route linking the two cities is along the  M1 and N1 in the Republic of Ireland and the A1 and M1 in Northern Ireland.
  
  There is also the Enterprise train service connecting the two city regions.
  There are three major airports: Dublin Airport (32.9 million passengers; 2018), Belfast International Airport (6.2 million passengers; 2019) and Belfast City Airport (2 million passengers; 2019) which together deal with over 40 million passengers each year.
  For the two cities:
  Dublin is served by the Dublin Suburban Rail network, Dublin Bus network, Luas tram network, Dublin Area Rapid Transit and the planned MetroLink.
  Belfast is served by the Belfast Suburban Rail network, Metro (Belfast) bus service, the new Glider (Belfast) bus rapid transport system and some Ulsterbus services.
