The MTA is looking for ways to improve passenger wayfinding via improved screens and announcements. Better tech is good on paper, ETA's Blair Lorenzo told the New York Groove, but the real question is if it will actually be used to improve the rider experience, and not simply blast more noise.
Lorenzo noted that any new tech is only as good as the messaging its used for. New tech also opens up the opportunity, of course, for more advertising.

"That would only make the rider experience worse, further pushing people who can to ignore announcements while forcing those who rely on them to sift through an ever-increasing amount of noise," she said. "The best technology in the world is useless if it isn't used in a way that gives riders the information they need while otherwise respecting their time and attention."

I always thought under-slung BART wouldn’t fit through the Golden Gate Bridge towers, but it turns out BART is small and the bridge is huge. Here is a mockup in 1/100 scale, BART fits easily.

Announcement pollution is one of those things that’s a huge problem but complaining about it sounds like nitpicking. It’s a respect and safety issue. Training riders to tune out announcements has consequences when you finally announce something important!

The math behind high-level platforms *and* wide doors: Narrow doors/high platforms allow 45 passengers/min/door to flow through. The 50" (double-wide) doors increase that number to 75 passengers/minute/door. Two sets at the quarter points means the whole car can clear in 48 secs.

A 125 St subway should be a slam dunk. But at $7.7B for 1.25 miles, and with stations deep underground, current plans would not only build the most expensive subway in the the world, but would cost riders valuable minutes every single trip. It's not too late, however: www.etany.org/reports/digg...

The cost disparity between third rail and catenary has gotten a lot worse over the years because the costs of substations have exploded. In 1966, they were about $500,000 a pop -- or about $5 million today if they'd risen at the costs of inflation. But they didn't. Now they're like $30-$40m each.

Promises made/promises kept: Please meet the 1966 report that would determine the next 60 years of how LIRR would be powered: the third rail. If all the work on platforms and dwells by Ronan & Co. was planning that was way ahead of its time that got things very right, this is the opposite.

This morning, ETA commented to the MTA board on it's study extending LIRR electrification to the new Yaphank-BNL station. It's exciting to see electrification of commuter rail, however we urge the agency to study more cost-effective catenary for extensions. www.etany.org/statements/y...
ETA welcomes the MTA's commitment to study electrification and double-tracking to the new Yaphank-BNL station. But prior studies rested on assumptions that inflate costs and reduce benefits, jeopardizing the value of the project.
The LIRR's environmental assessment put electrification beyond Ronkonkoma at 25 million dollars per mile, in today's dollars. Recent international commuter rail projects electrify for 2 to 3 million dollars per mile — an order of magnitude less. The difference is catenary and modern installation methods. Catenary requires less track work and fewer substations, and supplies more power for faster acceleration. The MTA instead proposed third rail, a legacy technology.
We ask the LIRR to study catenary electrification, and to study railcars that run on both third rail and catenary, like the M8, and that clear every LIRR tunnel. ETA's "M10" concept is one example worth examining.
We also ask the LIRR to consider passing sidings rather than full double-tracking, as Utah's Frontrunner 2x is doing. That requires less track and signal work, freeing funds for service increases elsewhere. Several diesel branches carry more riders than this stretch of the Main Line, and deserve the same study.
Finally, this work should serve a region-wide goal: incrementally unifying on a single electrical standard, 25 kV 60 Hz AC Catenary, as expensive-to-maintain third rail equipment reaches its normal end of life.
Scoping the study this way will identify the most cost-effective ways to improve service for LIRR riders. We ask that you include these suggestions. Thank you.

The fundamental math of @etany.org 's thru-running proposal. There are 11 platforms at Penn. Assume 10 minutes per train. That adds up to 66 trains per hour, easily enough to handle the 48 tph of the Gateway tunnels. Lots of caveats and complexities but that’s the basic plan.

As part of the new Yaphank station announcement, the MTA announced it's eying an extension of electrification to Yaphank. Momentum 1 laid out a detailed case for why fixing the Montauk service and the Port Jeff service should be first -- transitcosts.com/momentum/#6
The opening of the new Yaphank-BNL station comes as the MTA launches a study of potential infrastructure improvements to support more frequent and reliable service on the LIRR Main Line east of Ronkonkoma Station. This portion of the branch currently has only one track and is not electrified, requiring trains to operate using diesel power and run less frequently.

The study will assess opportunities to upgrade signals, communications and other infrastructure; add a second track along all or part of the branch between Ronkonkoma and Riverhead; and electrify a portion of the branch east of Ronkonkoma. Adding a second track would build on the LIRR’s Double Track Project between Farmingdale and Ronkonkoma and allow more trains to operate in both directions. Electrification could support faster, more frequent service while reducing reliance on diesel locomotives.

As part of that work, the MTA will evaluate the supporting infrastructure required, including new power substations, and examine the costs and benefits of potential investments. The study is expected to be completed in early 2027, and its findings will help inform future conversations with the public about investment priorities across the LIRR system. This study is funded by the MTA's historic $68 billion 2025-2029 Capital Plan, which was fully funded by Governor Hochul and the legislature in the FY 2026 Enacted State Budget.
