The RTE archive has a piece on the opening of 4 new stations on the Maynooth Line in 1990 (Broombridge, Castleknock, Coolmine and Leixlip Confey).
The blurb contains many errors, including:
Referring to the service as “A new Dublin suburban rail line”. The Maynooth Line service actually started in 1981.
Stated that the original railway along which the service ran dates back back to the 1870s. The line actually opened in 1847.
Stated the railway was originally known as the “Great Midland and Western Railway”. No. The railway was originally built/owned by the Midland Great Western Railway.
