Limerick–Ballybrophy railway line

The Limerick–Ballybrophy line is a 52.5 miles (84.5 km) railway line connecting the city of Limerick with Ballybrophy in County Laois. The line diverges from the Limerick to Limerick Junction railway line at Killonan Junction and continues in a north east direction with five intermediate stops at Castleconnell, Birdhill, Nenagh, Cloughjordan and Roscrea. The line ends at Ballybrophy where it joins the Dublin-Cork Main Line.

Services are infrequent, with two trains per weekday in each direction from Ballybrophy to Limerick. In addition, there is a commuter service, forming part of the Limerick Suburban Rail network, which has one train from Nenagh to Limerick. The commuter train service runs Mondays to Fridays. On Sundays there is one train in each direction, Limerick-Ballybrophy. Services on the line are formed of IE 2800 Class (diesel) railcars.

This service is an improvement over previous timetables. The North Tipperary Community Rail Partnership lobbied Irish Rail to improve the timetable to suit commuters, which they duly did, to a limited extent. The service is mostly patronised by passengers who connect into morning Limerick to Heuston Station trains and evening trains in the opposite direction, at Ballybrophy Station.

The railway line has several speed restrictions, particularly close to Limerick city. Although the line offers a geographically shorter and more direct route between Limerick and Dublin, it takes almost an hour longer than travelling from Limerick to Dublin via Limerick Junction. The train is slower than travelling by car between Nenagh and Limerick. The railway line does not serve major employment and educational facilities in Limerick such as the National Technology Park and the University of Limerick which are located near the line.
