"The deliveries of the initial 28 vehicle orders will coincide with the arrival of Evergreen Line SkyTrain service in 2016 and an additional 28 vehicles may enter service in 2017. It is conceivable that thew new vehicles will be using the newest Bombardier Innovia Metro 300 specification designed by Bombardier in 2010.
Among the interesting portions of the document and perhaps the most prominent is “APPENDIX 2”, which details the technical specifications that the new vehicles must meet.
This portion of the document reveals important details about the configuration of the new trains. It specifies that there is a “centre car” (a vehicle insertion between two end vehicles) as well as that the number of cars in a basic unit is to equal 4. This points to the fact that while the individual vehicles themselves will be of simlar length, the new vehicles will be arranged in a 4-car articulated configuration which will be connected and walkable from end-to-end. If they were just married pairs, as with the current ART 200 configs, there wouldn’t be any “centre cars” – they would all be “end cars”. With TransLink is attempting to maximize per-train capacity, ensuring that all ART 200 (Mark II) trains operate with a 4-car configuration (2x 2-car married pair), this specification does make sense. Up to 56 of these new cars may be in service by summer of 2017.
At present there are only two other Bombardier Innovia ART systems in the world using 4-car long vehicles, being the implementations to exist in Beijing, China and Kuala Lumpur, Malaysia."
