When I spoke to the driver during the delivery of 4080-4084 w/e 4/8, I believe the plan had been to deliver a 5-car set per week, which would have seen 85-89 delivered w/e 4/15. Since that set didn't end up getting delivered until w/e 4/29, and the driver had said the plan was to get the Staten Island test set delivered w/e 4/29, I would guess they're a few weeks behind schedule for whatever reason. I still think it would be reasonable to see the R211S test set get delivered some time around mid-May or so.
Remember we still don't have the second half of the soft gangway set on property yet (4055-59), so that has to come some time as well.
