California High-Speed Rail: Progress Amid Challenges in the Central Valley
The California high-speed rail project, a bold vision aimed at transforming transportation across the state, is making strides in the Central Valley, despite facing a rocky road filled with challenges and delays. On January 6, 2025, California Governor Gavin Newsom joined California High-Speed Rail Authority CEO Ian Choudri to celebrate a significant milestone in the construction of the railhead—a staging area for laying down tracks for the future bullet-train route that will connect cities from Merced to Bakersfield.
What’s Happening at the Railhead?
Located between Wasco and Shafter in Kern County, the new railhead site marks the beginning of laying down steel rails for high-speed trains. This pivotal area will serve as the operational hub for transporting materials necessary for track installation, indicating a promising step towards making the high-speed rail a reality.
“Finally, we’re at the point where we’re going to start laying down this track in the next couple of years,” remarked Newsom, emphasizing the significance of this development. The railhead is not just another construction site; it symbolizes the persistent efforts to change the face of transportation in California.
A Journey Full of Hurdles
The high-speed rail project has been no stranger to controversy and challenges. First conceived to provide swift travel across California, the project’s history tells a tale of fluctuating timelines and ballooning costs. Originally initiated in 2013, the construction has continuously faced delays, with the anticipated completion date pushed from 2018 to 2026 for the first segments alone.
In a significant contrast to initial expectations, the financial requirements have surged, with costs for construction packages skyrocketing from a combined estimate of well under $2 billion to an updated total that now exceeds $8 billion across various contracts. This upward shift in expenditure has raised eyebrows and concerns, prompting scrutiny from both political figures and members of the public.
For instance, the first construction package, stretching from north of Madera to Fresno, originally bid at under $1 billion, now faces an anticipated completion at a staggering value of over $3.7 billion. Such changes have led to questions surrounding the project’s management and efficiency.
The Political Landscape
Adding complexity to the situation is the shifting political terrain as federal support has been uncertain. With President-elect Donald Trump slated to take office soon, there is apprehension regarding the potential withdrawal of federal funding that has supported California’s ambitious plans. Historical context reigns as the Federal Railroad Administration canceled nearly $1 billion in previously awarded grants during Trump’s first administration. However, the recent Bipartisan Infrastructure Law, passed in 2021, has provided a glimmer of hope by funneling additional funds towards the project.
State leaders, including Governor Newsom, maintain an optimistic outlook despite the political uncertainties. “We are in a very different place at this sacred moment,” he stated, reminding stakeholders of the project’s momentum.
Looking Ahead
The road ahead remains both exciting and uncertain. The California High-Speed Rail Authority is on the cusp of awarding contracts for track installation, alongside contracts for the purchase of trainsets set for testing operations. The goal is to have the Merced-Bakersfield line operational between 2030 and 2033, a target that promises to reshape commuting experiences in California.
As we move closer to achieving this transformative project, it’s essential to keep in mind that progress in such a complex endeavor requires not only engineering feats but also perseverance amid bureaucratic and fiscal challenges. The upcoming years will undoubtedly be pivotal in determining whether this bold vision of high-speed travel will reach its destination, but for now, California is laying the tracks for a new transit future—one spike at a time.
Stay tuned for more updates as we follow the California high-speed rail project through its journey from ambitious dream to infrastructural reality!

The A Line Light-Rail Extension from Azusa to Pomona: A Significant Milestone for Public Transportation
After a long-awaited journey, the extension of the A Line from Azusa to Pomona is officially complete and set to usher in a new era of public transportation in the San Gabriel Valley. This extensive 9.1-mile extension, which has taken over five years to construct, is positioned to enhance connectivity and mobility for residents and commuters alike.
The A Line extension is set to open to the public this summer!
A Monumental Achievement
As reported in the San Gabriel Valley Tribune on January 3, 2025, the $1.5 billion project was officially handed over to LA Metro last week. This extension includes four new stations in Glendora, San Dimas, La Verne, and Pomona. The construction involved overcoming significant challenges, including health protocols during the COVID-19 pandemic and a series of unusual weather patterns. Despite these obstacles, the project was completed within its scheduled timeline, showcasing the dedication of the construction teams from Kiewit-Parsons (KPJV) under the oversight of the Foothill Gold Line Construction Authority.
Improving Accessibility
This extension not only connects the existing light-rail system but also extends the A Line’s total length to a noteworthy 60.8 miles, solidifying its status as the longest light-rail line in the world. Current ridership estimates suggest that the extension could lead to over 11,000 additional weekday boardings, significantly contributing to the overall ridership numbers. As of November 2024, the A Line saw an average of 70,425 daily boardings—a notable increase from the previous year.
City officials and transit advocates view this development as an important asset for the region. “This extension will solidify Los Angeles’ public transit system, providing a viable alternative to those stuck in traffic,” said Eli Lipmen, executive director of Move LA.
A Step Towards Greater Connectivity
The Pomona extension is strategically significant, as it brings the A Line closer to San Bernardino County. While not quite reaching the county line, the Pomona station is sufficiently close for many residents from western San Bernardino cities like Montclair, Ontario, Upland, and Chino to benefit from this light-rail alternative. Many of these residents will find it convenient to park at the Pomona station and travel to key job and entertainment destinations in Los Angeles, Pasadena, and beyond.
Montclair City Councilmember Bill Ruh emphasized the importance of this link, noting how it enables residents to access transportation services more seamlessly than ever before. The extension is paving the way for expanded public transit options, which are essential for families in the Inland Empire.
A New Transportation Hub
The Pomona Station holds particular significance as it will also connect with the Metrolink San Bernardino line, creating a crucial interchange for travelers. This synergy between the two systems is expected to elevate passenger traffic on Metrolink, catering to an approximate increase of over 2,000 daily passengers.
“Connecting these lines gives people more options for accessibility and commuting,” said Habib Balian, CEO of the Foothill Gold Line Construction Authority. “It allows for a travel experience that wasn’t available before.”
Future Prospects
Notably, this extension is just the beginning. Plans are already underway for an additional 3.2-mile extension from Pomona to Claremont and Montclair, anticipated to be completed by 2030. This initiative will broaden the A Line’s reach further into San Bernardino County and provide a meaningful alternative for commuters navigating the busy 210, 10, and 60 freeways.
As residents begin to utilize the new service, the Pomona extension will likely drive demand for additional transit options in the Inland Empire. Bart Reed, executive director of The Transit Coalition, noted the anticipated ripple effect in transportation services in the region.
The upcoming opening of the A Line extension from Azusa to Pomona marks an important step forward for public transportation in Los Angeles and its surrounding areas. By enhancing connectivity, providing more options for commuters, and anticipating future growth, this extension promises to offer significant benefits for communities in the San Gabriel Valley and beyond. As we prepare for the service to commence later this summer, residents can look forward to a more integrated, efficient public transit system that supports their daily travel needs.

Learning from Voices of War: Honoring the 80th anniversary of World War II’s final major battle
(Family Features) The Ardennes Offensive, commonly known as the “Battle of the Bulge,” stands as the single bloodiest battle fought by the United States during World War II. Waged in the bitter cold of mid-December 1944, it took the Allies a month to secure victory. The cost was staggering: nearly 20,000 Americans were killed in action, close to 50,000 wounded and another 20,000 captured.
In honor of the 80th anniversary of this pivotal battle, the Library of Congress Veterans History Project has launched an online exhibit to commemorate the milestone. While the battle itself is etched in the annals of history, the personal stories from those who endured it remain one of the most powerful testaments to its impact.
The online exhibit, “Serving Our Voices,” features accounts from 12 Battle of the Bulge survivors, part of the thousands of narratives preserved by the project. These stories ensure future generations can gain deeper understanding of veterans’ service and sacrifice.
One such story includes Eliot Annable, a 20-year-old radio operator serving with the Army’s 106th Infantry Division. Just days after arriving at the western front, Annable found himself under German artillery barrages on. Dec. 16, 1944. He recalled the assault in his oral history, describing the intensity as “almost enough to knock you on the floor.”
The following five days became the most harrowing days of Annable’s military service. While on a communications mission, he became stranded behind enemy lines and spent nearly a week evading the enemy in the Ardennes Forest without food, shelter or appropriate winter clothing. After traveling more than 30 miles, he eventually safely rejoined the remnants of his unit.
Back home, Annable’s parents were gripped by uncertainty. On Dec. 31, 1944, his father wrote a letter expressing the family’s anguish and love for their son, regardless of what happened. The moving letter, coupled with Annable’s oral history, provides an intimate view into one soldier’s Battle of the Bulge experience.
Another featured veteran in the exhibit, Guy Martin Stephens, also served with the 106th Infantry Division. Unlike Annable, Stephens was captured by the Germans during battle. In his oral history, he recounted the surreal feeling of combat, the relentless hunger he endured as a prisoner of war and the lingering effects of his time in captivity.
“It’s hard,” Stephens said. “It’s something you can’t ever … your mind is just like a video, or camcorder, I guess. You put it in there. You get busy and get married. You get home, and you get an education, and get a job, and raise your family and everything like that. You can kind of gloss it over or try to push it back, but it’s always there, you know?”
Veterans who served during the 20th or 21st centuries are invited to establish a collection, including interviews (video or audio), letters and original photographs, even if they did not see combat. Families can also submit collections posthumously to honor their loved ones. To explore more veterans’ stories and learn how you can contribute to the program, visit loc.gov/vets.
