  •  It does depend on what the time clipping ... (5+ / 0-)

    ... consists of.

    There's no time to be clipped on the Express HSR sections through the CV unless, for instance, the corridor is built for 180mph and you need to rebuild it for 220mph.

    The first four segments ~ the initial construction segment, then to Palmdale, then to the San Fernando Valley, then north to San Jose ~ are all bullet train corridor, and there's nothing that you could pinch pennies on without making the cost of hitting the target time explode through the roof due to the rework.

    But if the electrification of the Caltrain Corridor is done when the Bay to Basin is done, but the DTX is not finished, then running at 110mph to 4th and King instead of stopping at San Jose would work. As upgrades proceed, the HSR would spend part of each trip creeping along shoe fly tracks to get around each stage of grade separation to finish the corridor for 125mph, but it would be a single seat ride, and under 3:30 to the LA Basin in any event.

    At the LA side, given the number of individual grade separations, they are either going to raise or lower the grade of the whole corridor. The time to do that is before the HSR is using is, since as it stands there is ample space in the corridor itself to put track at grade along one edge, work in the other side of the corridor, put a pair of tracks in there, then do the same work and complete a four track system. That'll work whether its trench or berm. So its after the grade separations work is completed that the HSR can plan on using Burbank / LA Union Station.

    Now, the plan does not include that section until the final stage, but if its available earlier, of course you'd use it. If the LA Union Station / Burbank corridor work has been finished when the Express HSR corridor is completed through to the San Fernando Valley, the HSR First Service will obviously just run through to LA Union Station.
