I assume that they'll add in the "enhanced variable tension" catenary supports where they failed to install constant tension, as seen here in Hamilton. Again, I can't imagine they spent all this money and did all this work for nothing, but then on the other hand, this is Amtrak we're talking about - the same Amtrak that's sending the rebuilt Turboliners to the scrapper after getting no use out of 'em, and that spent a couple billion on the Chicago - St Louis route only to stay stuck at 79 mph with 110 mph always seemingly promised for "next year" for at least the last five years, and that's currently using the new Viewliner dining cars to serve cold snacks in a box. So, I guess anything is possible.
