Nope, and there likely won't be.
And no, the reason isn't that the work isn't ready to be done. It is.
But the problem is that with all of the other work being done on the corridor this weekend that there was not a way to move a train into place to test the various elements after the work was done on Sunday night. Which means that the first train over the work would have been the first southbound revenue move on Monday morning. And that is not an option for any number of different reasons.
They'll postpone the cutover by a couple of weeks, and ensure that it won't coincide with too much other work going on in the corridor so that they can have the test train ready at the site.
Makes sense. Safety first.
