Getting back to the origin of this discussion, yesterday Cuomo disclosed a study indicating that the Hudson tubes could be repaired while in use, like the L train tunnels were repaired. From NY's standpoint, most of the benefits come from the repairs (by staving off catastrophe) and not from extra capacity. The ideal situation for NY, then, is to get the repairs done independently and let NJ and the Feds figure out how to pay for Gateway without NY's help.

New Jersey leaders are
outraged that New York doesn't want to subsidize their commutes...
Might be a moot point though if Biden orders DOT to release funding for full Gateway.
