Meanwhile, only a handful of the many surface light rail and commuter rail stations are in locations that equal the least-successful heavy rail locations.
Piggy-backing the expense of grade separation and electrification for commuter rail with HSR makes a lot of sense, however. But the political strategy in LA and across the United States is to create new mediocre services rather than upgrade existing services to something resembling heavy rail performance. The new downtown light rail subway is an exception to this, but a rare exception.

It's still puzzling to me that there are some who still genuinely believe that LRT will suffice, given its many competitive disadvantages:
1) Lower capacity
2) Less frequency
3) Slower speeds
4) Risk of delays from collisions
5) Lack of signal priority
At-grade, street-running segments along any portion automatically affect the entire line and its car-competitiveness, which therefore reduces its overall utility.
This is before even mentioning perceived public safety issues, which along with the pandemic, have really quashed a lot of the momentum built after the passage of Measures R and M. As a result, the D Line extension will probably not generate the level of ridership as initially anticipated, which in turn could reinforce the notion that such a large capital investment isn't worth the ROI and that Metro doesn't need to operate trains at higher frequencies.
At this point, I think our best hopes moving forward are:
1) The D Line extension to the VA opens in 2027, prompting questions and enthusiastic conversations about extending it all the way to Santa Monica
2) Bechtel's bid for the Sepulveda corridor wins, and its innovative approach provides a useful template for HRT expansion moving forward (e.g., shorter, more frequent trains, 21-hour automated operations, smaller station boxes) and sets an important precedent for elevated heavy rail in LA
3) The novelty of the Brightline West ignites talk of mainline ROW upgrades (e.g., double, triple, quadruple trackage) and Metrolink electrification
