Clearly common sense escapes your sense of logic. You're obviously trolling to have flamed someone's post when it was completely factual. Anyone who understands project management understands that the size of the project can change. It was never a cost of $700M to do the work that was originally contracted for $250M. That is all BornRuff was saying. You had to start crying about what he wrote was crap.
What does understanding what one can buy for $700M have to do with anything? As pointed out earlier, what is out there right now certainly isn't all that we are getting for that money. A portion of that cost has gone into development for future upgrades and the future deployment of it. By the time that is rolled out, it may be one of the most expensive transit systems in the world but it will also be the most advanced.
