ETA is here in Berlin and will be all week for InnoTrans to bring the best insights back to New York from the biggest public transit showcase in the world! If you'd like to meet with our team while we are here, we'd love to hear from you, feel free to drop us a message!

I was seeing this on the way out of a station earlier. I’m wondering if connecting busses could be shown instead.

Rock trains do come down New Haven others stuff heavily via Hudson, Iirc those 1-2 Hudson trains include the LI freight.

What is the distance from Wayne junction on that?

Yes, but that’s entirely because they never bought tap changers for the arrows. This has always been fixable, but at this point with them this close to retirement is not likely worth the effort.

They haven’t in decades, but this would prevent it for another generation.

I don’t think it helps with cost, but I don’t think it’s impossible either.

This series of posts is something that was discussed the last time this came up. It discusses boarding, electrification (25hz only) and much much more alejandrogonzalez1.substack.com/p/how-septas...

Unfortunately I believe it. It still is not helpful that it complicates upgrading the NEC’s electrical system for another generation.

Which is also nuts, they not to recently rebuilt Wayne junction and could have prepped it to go to 25kv 60hz over time similar to what NJT did with the coast line. It also makes it hard to expand the system on 25kv

Madison - ProgWML6 @progwml6.bsky.social · 15/05/2026
The lack of 60Hz and 25kv compatibility in this RFP for catenary is so odd. Everything else other than possibly the SL IV’s supports 60 Hz supports it.

Madison - ProgWML6 @progwml6.bsky.social · 24/02/2026
Yet they didn’t require 25kv in the RFP which I find shocking, as it makes expansions of the network more expensive for what’s a rounding error when building stock now

The track that connects the NEC to the Hoboken bound line is called the waterfront connection

There have been less cars south of Trenton for years, and the second waterfront track is in the NJT capital backlog

We also have discussed this project and the rest of NJT in several pieces since then.

Extending the Second Avenue subway across 125th St is a great concept, but the current project is deeply flawed: * At $7.7B for 1.3mi, it will cost an order of magnitude more than similar lines in other global cities. * Deep stations will waste a lot of time—over 10 min across 125th.

The western extension of the Second Avenue Subway has a $7.7-billion price tag that calls into question the very logic of building it at all — but advocates and researchers say the train is a good idea that could cost a lot less with some minor alterations.

NYCT only builds new lines to B Division specs. None of this discounts expanding the 7, and at the costs involved, i'd rather just extend both across the Hudson, if anything goes from the village/chelsea across.

you could also do HBLR + heights, as a HBLR connection is helpful regardless to relieve the transfer loads to the path
000
Madison - ProgWML6 @progwml6.bsky.social · 13/01/2026
you have two options, one is you put a single station at 9th st HBLR, the other is you put a station in central hoboken, and another to cover the heights south of the split point. there are pros/cons to both. and I haven't really analyzed them enough to have picked one
100
Madison - ProgWML6 @progwml6.bsky.social · 13/01/2026
yes, My plan would have them share several stops, one near Chelsea piers, Stephens, 1-2 intermediate stops, then they split near JFK

Madison - ProgWML6 @progwml6.bsky.social · 13/01/2026
My question is really what’s the deepest station that you can do and get under the river?
100
Madison - ProgWML6 @progwml6.bsky.social · 13/01/2026
The path underlining is another complexity here. That, and ALM through the arches up to the meadowlands also fit into this, as do future through running tunnels. There are a few key pieces that have to get built, which services use them is a whole other problem.

Madison - ProgWML6 @progwml6.bsky.social · 13/01/2026
And the circulation issues are fixable at some of those stations for the L.

Madison - ProgWML6 @progwml6.bsky.social · 13/01/2026
What geometry problems are you referring to?
010
Madison - ProgWML6 @progwml6.bsky.social · 13/01/2026
Part of this is a third issue that gets fixed regardless, if you have 2+ lines, one is going from JSQ up JFK till it can go up bergenline or central at least to Nungessers to handle north/south issues in north Hudson and southern Bergen counties.
110
Madison - ProgWML6 @progwml6.bsky.social · 13/01/2026
The Q is not going to help downtown JC at all, you would need to go uptown to 125th and back down to use it for most destinations. If you send it across, it’s got to help communities further north.
130
Madison - ProgWML6 @progwml6.bsky.social · 13/01/2026
Need to run the math on this one with 5.5% grades, and tunnel depths the same as the shallowest Hudson crossing to see what’s possible.
120
Madison - ProgWML6 @progwml6.bsky.social · 13/01/2026
Which goes north/south would depend on loads, yards, and o/D pairing, but yes, one would go up Bergenline/ central and the other down JFK to Bayonne also relieving JSQ in the process
110
Madison - ProgWML6 @progwml6.bsky.social · 13/01/2026
My current thought is to send both the 7 and L across from near Chelsea piers up to Stephens, and split them near JFK. The geometry isn’t relevant you would build to IND standards regardless, and JC/Hoboken/Bayonne, and other towns nearby can use the extra capacity from 2 lines plus the Q/T north
010
Madison - ProgWML6 @progwml6.bsky.social · 13/01/2026
I think you are solving different issues here. The 7 and L would serve JC and Hoboken far before they help north Hudson towns and south Bergen ones. Either way, future proofing the terminal to be able to cross the river is not a difficult task.
330
Madison - ProgWML6 @progwml6.bsky.social · 13/01/2026
If you get it across the river and route it to a new build bus hub at Nungessers it would be a huge net positive to NJ. At a bare minimum it should be future proofed to go across the river.

Great news: Gov Hochul has reportedly decided to veto a bill requiring two-person train operation. This poorly-considered bill would've mmediately impacted services that are currently run with one person, and would've make it impossible to fully automate new lines like the IBX.

The bill on Hochul's desk mandating 2PTO on the MTA, Assembly Bill A4873, still hasn't been vetoed. If it's not by the end of the day it will automatically be law and worsen service on small shuttle trains and off-peak services as a result Call her office at (518) 474-8390 and demand she veto this

With all this, I’d really like to see updates on how we generate ridership estimates for rail projects considering just how many have vastly improved over projections as of late, it makes the economics that much easier regardless of the need to lower construction costs

Madison - ProgWML6 @progwml6.bsky.social · 16/10/2025
It’s definitely good news overall, but I would like to see more concrete info on if or how they are planning on avoiding accidentally selling off land needed for service expansions and electrification in future.

Something like this tech from the Netherlands infrafoundations.nl/en/project-h... which they also use for catenary foundations or precast foundations you can just bury in the ground would be quite helpful if attempted nowadays
infrafoundations.nl
Project HKVs in collaboration with Rijkswaterstaat.
Rijkswaterstaat has recently started laying the first foundation piles in Groningen, at the Gerrit Krol Bridge. We have been asked to lay the foundation.

Definitely not my preferred option to do it by hand, fortunately in 2025 there are plenty of electronic solutions to avoiding voltage or ac/dc trouble. There are also ways to avoid the need for neutral sections using SFC’s when at the same voltage.

Not necessarily although that would work. Some railroads eBay swap pans just drop and coast. You could also add a switch in the cab, or if one exists just add another position.
