Charles Stewart Parnell turns the first sod for the construction of the West Clare Railway (WCR) on January 27, 1885, although actual work on the line had begun in November 1884. The line is opened on July 2, 1887.

At the end of the Great Famine there is a new growth in local businesses. The British Government determines that an improved railway system is necessary to aid in the recovery of the West of Ireland. The West Clare Railway and the South Clare Railway are built by separate companies, but in practice the West Clare Railway operates the entire line. The lines meet at Milltown Malbay. In due course the entire line becomes known as the West Clare Railway.

The West Clare Railway originally operates in County Clare between 1887 and 1961. The 3-foot narrow gauge railway runs from the county town of Ennis, via numerous stopping points along the West Clare coast to two termini, at Kilrush and Kilkee, with the routes diverging at Moyasta Junction. The system is the last operating narrow gauge passenger system in Ireland and connects with the mainline rail system at Ennis, where a station still stands today for bus and train services to Limerick and Galway. Intermediate stops include Ennistymon, Lahinch and Milltown Malbay.

On 27 September 27, 1960, CIÉ gives notice of its intending closure with effect from February 1, 1961, despite the dieselisation of passenger services in 1952 and freight in 1953. CIÉ says that the West Clare is losing £23,000 per year, despite the considerable traffic it handles. In December 1960 it is announced that the line would close completely on January 1, 1961 although actual closure does not take place until January 31, 1961. CIÉ begins dismantling the line the following day.

A preservation society maintains a railway museum at Moyasta Junction station, and successfully re-opens a section of the railway as a passenger carrying heritage line with diesel traction in the 1990s, and with steam motive power from 2009.
