If Amtrak were to get on the same page with either Caltrans and Nevada DOT (or both), it could counter Brightline West’s pending service just in time for the next Summer Olympics in three steps.
The first step would be to roll out conventional Los Angeles-Las Vegas service with four or five roundtrips during the Olympic Games (and then cutting back to its planned two roundtrips as per ConnectsUS afterwards). Part of the inspiration comes from this article from 2021.
Secondly, if Amfleets, Horizon Cars or surplus cars from California prove to be unavailable, then, the soon to be discontinued Talgo Cars should be the first backup plan once the Cascades get the new Airo equipment. Another strategy would be to borrow commuter equipment that isn’t being used and tidy it up until Amtrak can get its older fleet to the West Coast.
