"When this is built, I want New Yorkers to take it for granted” Thank you to @thecity.nyc @amysohn.bsky.social and Harry Siegel for having my on the podcast to discuss QueensLink! www.thecity.nyc/2026/03/07/q...

We've posted the slides and a printer-friendly version of our subway expansion report, A Better Billion! Slides: transitcosts.com/ABB_Presenta... Printer-friendly PDF: transitcosts.com/A_Better_Bil... NYT write-up: www.nytimes.com/2026/01/30/n... The OG interactive: transitcosts.com/a-better-bil...

We at the Transit Cost Project are hosting an event on our most recent report, "A Better Billion", at 370 Jay St in Brooklyn on March 4th. If you are interested in hearing about the planning proposal in person and ask your burning questions on the report, RSVP on Luma here: luma.com/ub7q20a6

Now I want a (12) train shirt to go with this.

✨ introducing… ✨ 🌇 Transportation for the Abundant Society 🚅 "Abundance" says our problem is artificial scarcity—especially housing. But you can’t build your way out if transportation policy still treats traffic flow as sacred. Transportation is the binding constraint. ssrn.com/abstract=538...

Some questions I ask whenever I see a crayon like this:

I don't think we wrote it to be synergistic in the first place.

Hi Zohran, we at the Transit Cost Project just published a report planning for how the New York City can build affordable housing and good transit together - all year long, for 40 years. Let's plan a city that plans for the future, together. transitcosts.com/a-better-bil...

No notes. Love the header image @davecolon.bsky.social nyc.streetsblog.org/2026/02/02/f...

I am now off the clock, so I am officially, formally, incredibly thrilled that 'A Better Billion' is now in the world. And it's absolutely surreal to help with something that ends up with a feature in The New York Times. -- transitcosts.com/a-better-bil...

It has been fun working on the A Better Billion project over the last couple of months. You can check out the full StoryMap here: transitcosts.com/a-better-bil... Also the gift article link to the NYT coverage of our plan; www.nytimes.com/2026/01/30/n...

This "beigeness"accompanied me through high school 🙃

Line 5 and 6 can be the prime examples of Jumping-out-hole-we-dug-for-oursevles-ism. I still remember the time when I saw the TTC getting award for best transit system in NA (2017-ish). H(C)opium: maybe Line 3 can avoid these pitfalls and try to build a REM-esque service in Toronto.

I wrote a thing. Build trams, but build them well. Understanding what tramways are, what they do best and how to employ them. open.substack.com/pub/marcochi...

Bill C-15 for Toronto-Quebec City High-Speed Rail (TQHSR) has been tabled for first reading in the Canadian Parliament. www.parl.ca/DocumentView...

An update:

It's an honor and pleasure to be named to City & State's "2025" Unsung Heroes" list. I have to also shout out the amazing volunteers at QueensLink who make it look easy when it's not. www.cityandstateny.com/power-lists/...

New Marron survey of 400+ subway lines across the world from London to Paris to Shanghai finds just 6% still use two-person train operation, which would be required by a TWU-backed bill. “It doesn’t really matter to us what the data shows,” says TWU boss Samuelsen www.nytimes.com/2025/11/13/n...

We dropped a new report re: train operations, everyone’s favorite topic. There’s some backstory that we will get too. But, the basic takeaway is modern train systems have moved away from two-person train ops. New York should, too! transitcosts.com/Train_Operat...

↓Mood for the rest of the day

@ndhapple.bsky.social Hey look they are looking to make the descendant of the traincar in our acceleration curves tables

If only we have some land-based alternative that can move a lot more people on a dedicated alignment... You know, to compensate for the loss in flying capacity...especially for this route, too.

Scared about kill switches in buses Norway bought from China? How about trains in Poland with something similar but even more malevolent 👇 jonworth.eu/newags-digit... Ah no, not China, so doesn't generate the same fuss 🤷‍♂️

I've done something that I don't do very often. I wrote a short, quick polemic post. It was prompted by a discussion in here. It's about why I'm still skeptical about ALTO's HSR project and why there is no way around transparency in public projects. open.substack.com/pub/marcochi...

The Canadian 2025 budget tabled by the Carney administration, describes the Alto HSR project in a very specific, defined goal. The full budget can be found here budget.canada.ca/2025/home-ac... 1/thread

You know what? A better city is possible.

I finally completed my second long form post dedicated to the problem of High Speed Rail and the city, or "who goes with whom in the puzzle of traffic separation around large urban areas?" I hope you enjoy. open.substack.com/pub/marcochi...

The NEW, interactive website for our NEC report (by @alonlevy.bsky.social) is ready! nec.transitcosts.com

We will discuss free buses for at least the next year! Free buses are okay. Faster, more frequent buses and a more expansive fair fares is better. Let’s translate @zohrankmamdani.bsky.social’s enthusiasm for buses into real change in the next administration: www.npr.org/2025/10/16/n...

“Massive NY tunnel and subway projects still alive,“ “DOT has no plans to end the multibillion-dollar Gateway tunnel and Second Ave Subway projects, an administration official told POLITICO a day after the president said they had been ‘terminated.’” subscriber.politicopro.com/article/2025...

Meanwhile in New York City...

I just can't get over the differences in scale between Ballard Link's Westlake Station as proposed and the original Westlake Station, off to the left.

What's the incentive for politicians when they get reflected even if Metrolinx's leadership set money on fire in Dundas Square. Ontarians deserve that because they voted for that.

🚌 Strategies used to turnaround Akron’s bus system: 1. CEO used to be a bus driver, now rides the bus with customers 2. Run buses every 15 minutes, 7 days a week 3. Concentrate on most needed services 4. Reduce job requirements “If we’re not using our product, why should anybody else use it?”

NYC: we need a ventilation building for air intake and smoke extraction, so it's at least 40 feet above street level. Actually, we need two for each station. NFPA 130: extraction/intake should be a couple of feet above street level, so one can't park above it. Copenhagen:

This concise description is not stressed enough. With urban rail there are more benefit to apply quad tracks instead of continuously adapt bypass track designs on certain high-throughput corridors over longer distances. Even so when commuter rail and urban rail share the same corridor.

Not sure if Transit Bluesky missed this, but the FTA is seeking public comment from all transit stakeholders on streamlining and improving the Capital Investment Grants (CIG) process. Comments are due in 3 days! www.federalregister.gov/documents/20...

When I commuted from San Francisco to study at Stanford in the late 1980s, the San Francisco peninsula rail line @caltrain.com was a primary limiting factor on my education. It ran every two hours and stopped at 10 PM. Why? 🧵 1/

House GOP released proposed appropriations for FY 2026 for housing & transportation, proposing: —$2 b increase in highway funds—but a $1.8 b cut in transit spending, essentially eliminating new grants for transit lines. —$900 m decrease in housing funds, including no new funds for the HOME program.

Mamdani, campaigning for bus improvements: "Speeding up buses isn't complicated... all the tools are in the power of City Hall... we just need a mayor who will deliver for the more than one million New Yorkers who ride the bus every day."

Hong Kong announced funding schedules Phase 1 of the MTR Northern Link. By moving to mainland standards, the legislative committee claims the cost has been reduced to 39.1 Billion HKD and a firm opening date no more later than 2034. www.stheadline.com/society/3471...

Bringing in HSR to city centers has always been a touchy subject, even for Chinese cities. Barring Shanghai and Beijing, many other Tier I/II cities first introduces HSR at a location 10-20km from the traditional center and then considers how to introduce it into the city center in the next wave.

If there is one single thing that the R211 series designs have done right, it would be the generous application of exterior and interior LCD displays. Just saw a passenger enthusiastically filming two R211s running between each other with grin on their face.

HTML Post of Momentum is up. Reposting this after a memorable early morning Amtrak trip highlighted by failing Acela I equipement (Ch. 9.1) and ACS64/ Amfleet I intercity cars (Ch. 9.2) that came to the rescue for the stranded passengers. Fleet and route modernization cannot come soon enough!

This reflects my priors re: how Mamdani will actually govern. It’s always nice when history provides some support. New York’s longest serving mayors found a way to build coalitions across divides. I hope we see that again: open.substack.com/pub/culturea...

The informatic system of the Go at union just continue to remind me how sad the current fallout between olde Canafian Railroaders and DB is. Their IT infrastructure is ready for the Go to become a regional system yet the mindset seemingly isn't.

Technical pragmaticism is always easiest to say and hardest to do.

One lesson that man learns from history, is that man seldomly learn from history. Or so I am told.
