Belfast–Bangor line

The Belfast to Bangor line (known simply as the Bangor line by NI Railways) is a railway line in Northern Ireland, originally part of the Belfast & County Down Railway. All services are operated by NI Railways, the only operator for Northern Ireland (NI). Unlike the rest of the United Kingdom, no railway in NI is part of the National Rail network and none is owned by Network Rail. Services run every half-hour, with extra services at peak times.[1]
