They have decreed that there by golly, nope, won't be light rail tunnels under Marquam Hill with elevators to OHSU, and they aren't going for a tunnel under Hillsdale - but they might run a tunnel over to PCC/Sylvania campus, maybe. Translation: we're still paying lip service to "studying" BRT, but we really want to spend more billions on light rail.
The only reason they've opted to dump their longed-for choo-choo tunnels is because doing that would add so much to the cost that even the feds wouldn't contribute. Naturally, they claim not to want to disrupt businesses in Hillsdale or operations at OHSU, but neither of those considerations would matter if they could find a way to get their paws onto the necessary money. It's how they roll.
