>> as it is commissioners both said, earlier this morning, we received an alert of the explosion that happened in the tunnel and immediately the mta and transit authority shut down the lines on the 8th avenue line, the a, the b. many of them were rerouted. i will tell you right now they are all back. the only disruption we have right now is both the 7th avenue line as well as the 8th avenue line, we're bypassing the times square 42nd street corridor and also the shuttle between grand central and times square is shut down. we expect it to be back up and normal by this evening's rush hour. i do want to also state that on november 6th, just a month or so ago, we had a tabletop exercise with the nypd to coordinate our efforts in the event that something like this ever happened and the result of that was today in less than two hours we are back totally up to speed
