Dublin Metro - Metro West

Two potential routes for Metro West were published by the Railway Procurement Agency in January 2007, with a number of sub-options also included. Following discussions and a public consultation process, the preferred route was announced in July 2007. This route starts at Tallaght, then continues on through Belgard, Clondalkin, Liffey Valley, Blanchardstown. Stops are also planned for the National Aquatic Centre and Abbotstown, before continuing in the direction of Sillogue and Harristown. Following Harristown it will link with the Metro North, after Northwood and before Dardistown station. The line is expected to be 25 km long.

Although the Metro West is currently in the early planning stages and can change at a later stage, according to the design drawings produced by the RPA, the Metro West line will not be segregated from road traffic, unlike the Metro North proposal. Metro West will run overground, with some tunnels and bridges to avoid major road junctions. The preferred route will also see a number of interchanges with other modes of public transport. As well as the link with the Metro North, the line will also link with the Luas at Tallaght and Belgard, rail services at Fonthill and Porterstown and Dublin Bus services at a number of other stops. Park and ride facilities are also proposed at a number of stops.
