It’s all happening guys. Okay, maybe not “all.” But when it comes to the Second Avenue subway line, a pipe dream like no other, even “a little bit” of progress is better than nothing. So, rejoice: Phase I is finally set to be completed this December. The MTA is already test driving trains on the new line, as you can see in the positively riveting video above. And this morning, Congresswoman Carolyn B. Maloney, who’s brought buttloads of money to the project in recent years, gave the MTA an A+ on its Phase I report card, part of the representative’s initiative to oversee progress.
