 Light rail was eliminated on cost grounds, and the entire Belfast Rapid Transit project is now planned as bus rapid transit.Originally much of the EWAY was to be routed along the trackbed of what had been the main line of the Belfast and County Down Railway (BCDR) between the site of Ballymacarrett Junction in East Belfast and the former Dundonald railway station in County Down.In 2003–04 the Knock Valley Relief Sewer was laid along of the former BCDR trackbed, flowing from Dundonald to Ballymacarrett.
