if you can't get through the paywall here are some significant quotes:

"The NTSB doesn’t have the power to regulate railroad operators, so the state is free to continue using them, she said."

"Matkin said the state was planning to procure new trains around 2025 and will expedite that schedule somehow."

"Washington owns two 13-car Talgo Series 6 trainsets, and Amtrak two others, that would require a combined $100 million to replace, said Janet Matkin state rail spokeswoman. Another set damaged in the crash may also be replaced. Oregon owns two more Talgo trainsets that are different and not criticized by the NTSB, Matkin said."

"owen said two Talgo Series 8 trains are unused and for sale in Wisconsin. Or the state could run standard trains from Seattle to Vancouver, B.C., while dedicating Talgos to the curvier, busier section between Seattle and Portland. Modifications to Talgo 6 may be possible, said Bowen."

"Unlike on typical trains, whose wheel and axle frames are horizontal under the car, the Talgo railcars in the DuPont crash had wheels at the bottom of large vertical posts that the NTSB said broke loose on impact. Nylon straps that secured wheelposts to the railcars were past their useful life, a finding said."


"NTSB staff said the Talgo Series 6 trains, made of lightweight aluminum, uncoupled and ruptured. Two of the passengers killed were ejected from a railcar that broke loose, while a third was struck by a flying wheel assembly, investigators said."
