Broombridge is a railway station serving Cabra, Dublin 7, Ireland. Unlike most stations in Ireland, it is a halt. It lies on the southern bank of the Royal Canal at the western end of what had been Liffey Junction station on the erstwhile Midland Great Western Railway. It takes its name from Broome Bridge, which crosses the canal, a place best known as where William Rowan Hamilton discovered the mathematical notion of quaternions. A plaque on the adjacent canal bridge commemorates this.
The station was opened on 2 July 1990. Unfortunately, the station is in a state of poor repair, due to vandalism. There is no station building, as the previous building - a metal structure - was set alight during the 1990s, there are no intact benches, and the majority of the station signs have been removed. While running services to the 2006 Ryder Cup through the station, Irish Rail burnt graffiti off the platform surfaces and painted over graffiti on the enclosing fences and remaining shelters - as well as a number of the station signs. As present, the only signs of it being an active station are a copy of the Western Commuter timetable, and a few station signs. The platform surface is roughly laid tarmac, as the surface of interlocking blocks, common to most stations on the line after the service upgrade in the late 1990s was being gradually lifted and being used as ammunition by local youths to damage passing trains. It is the last station served by both branches of the Western Commuter line, prior to the split on the line. IÉ plan to reinstate Liffey Junction just beyond Broombridge to run services into Dublin Broadstone.
