The only new feature worth a damn in that whole story is adding more countdown clocks, but even that just quantifies but does not in any way reduce the waiting time.
Typical case of totally different priorities between NYS and NYC. Cuomo obviously does not ride the subway. NYC needs to secede already
Edit: I didn't notice the price is $27 billion. This makes me angry. That's enough to make some pretty substantial "real" boring improvements that would actually improve service. According to wikipedia Phase I of the Second Ave Subway cost "just" $4.5billion. And we're going to blow $27 billion on prettier signs? Are you !@#$% kidding me? I wish I could vote against you more than once, Cuomo
Edit 2: To be fair, there is one useful feature of the new trains: More space to pack more passengers with the "open gangway" design. But the rest is a waste
