When Metro West was in the early planning stages, the design drawings produced by the RPA indicated that the line would not be segregated from road traffic, unlike the Metro North proposal. Metro West plans, published in 2007, proposed lines which would run overground, with some tunnels and bridges to avoid major road junctions. The proposed route included a number of interchanges with other modes of public transport. As well as the link with the Metro North, the line would 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. As of 2007, park and ride facilities had been proposed at a number of stops.
