Answer:
The argument is a bandwagon fallacy, because, yes, Phoenix is growing, but that does not call for having a light rail. Just because other major cities have a light rail does not mean a city which already have other modes of transportation that already works really well would need a light rail. This is a bandwagon, for the publisher believes that for Phoenix to be able to "become a major city", they must have a light rail like all the other major cities. This is a fallacy, and is just a group of people trying to tack on the title of major city through building a light rail. In this case, if a small town of a couple hundred can build a light rail and call themselves a "major city". Does it meet this fallatical statement? Yes. Does it make the town a real major city? Not in the near future, if at all.
