Broadstone railway station was the Dublin terminus of the Midland Great Western Railway (MGWR), located in the Dublin suburb of Broadstone. The site also contained the MGWR railway works and a steam locomotive motive power depot. A Luas tram station opened at the front of the station in 2017.

The Midland Great Western Railway (MGWR) was the third largest Irish gauge railway company in Ireland. It was incorporated in 1845 and absorbed into the Great Southern Railways in 1924. At its peak the MGWR had a network of 538 miles (866 km), making it Ireland's third largest network after the Great Southern and Western Railway (GS&WR) and the Great Northern Railway of Ireland.
