\r\nStage 1 of the Ion project involves constructing a 19km 16-station light rail line from Conestoga Mall in Waterloo city to Fairview Park Mall in neighbouring Kitchener, together with a 17km Bus Rapid Transit line from Fairview Park to Ainslee Street in Cambridge.\r\nThe light rail line is being constructed by the GrandLinq consortium under a 33-year design, build, finance, operate, and maintain contract awarded in 2014.\r\nBombardier is supplying 14 Flexity Freedom LRVs worth $C 92.4m ($US 70.9m) with an option for 14 additional vehicles. The LRVs are being supplied as part of a larger order for 182 vehicles for Toronto and Hamilton transport authority Metrolinx. However, the programme has been beset by delays and has recently erupted into a legal dispute between Metrolinx and Bombardier.\r\nThe first vehicle for Waterloo was originally due to arrive in August 2016, but last April Bombardier told the regional government that it would not be able to deliver the LRV until October. In May 2016 the region pushed the opening date back to 2018 when it became clear that deliveries would not start before December.\r\nTesting of the first vehicle is now expected to begin in the Spring on the section between Northfield station and the intersection of Caroline and Erb in Waterloo. The LRV will be publicly unveiled at the line\u2019s depot in April.\r\nWhile Bombardier originally intended to build all 14 LRVs at Thunder Bay, assembly of the 13 remaining vehicles has now been switched to the company\u2019s plant in Kingston, Ontario. The first of the Kingston-built vehicles is due to be delivered to Waterloo in June or July.
