Railroad signals and other train stuff! Twitter Refugee. New Jersey Proud. Ask about my Christmas week SEPTA Trip.
I just saw a stripped SEPTA M-4 car on a flatbed trailer heading northbound on US 13 in Bristol.
Couldn't get a photo 😭
@alanthefisher.bsky.social any idea of what's going on?

It's interesting how Bristol, PA is a perfectly nice small city, but generates so little SEPTA R7 ridership. Compare to Croydon which has high level platforms and a generally full lot.

Amtrak s westbound Pennsylvanian Train 43 passing by the Milepost 21 intermediate signal on the Main Line.
These might be the most recent main line instances of G grade plates in North America.

TFW you accidentally get into an NEC vs I-95 race and realize you'll have just enough time to get into position for a video of your friend passing on a Next Gen Acela.
Made it with a cool 45 seconds to spare and I only had to pull off my usual route via Del Rt 279 near Newark.

When I saw this I figured the bonuses were cumulative, so 500 points for each level.
Turns out they are additive! So I'm currently on a last minute round trip to DC for a happy hour event 😅

Another problem with eliminating the 30-day Metrocard that @thelirrtoday.com briefly touches on: it *encourages* fare evasion. If every ride is an incremental cost, you're going to take opportunities to avoid that cost. Meanwhile, the MTA is spending millions to solve a problem they're exacerbating.

The switch away from sunk cost unlimited passes encourages riders to penny pinch and fare evade instead of using the services as much as possible.
Almost like the MTA doesn't want to deal with the hassle of ridership growth. 🙄

Does anybody know what rail cars would have been moving through Catawissa, PA around Thanksgiving last year? I assume they are heading down from Alstom. They look like an NYCTA NTT, but Alstom didn't have an R211 contract 🤔

Leftists are so fucking dumb. ACA premiums skyrocketing are a GIFT for the midterms and anti-GOP sentiment.
Do they really want people getting a healthcare check with Trump's name on it?

A Sharon Begley byline, almost 5 years after her death.
Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."
Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.

The key factor that everyone seems to always forget is that Trump was the host of what was once the highest rated show on network TV - a purportedly non-fiction show that portrayed him as a hyper-savvy and hyper-successful businessman.
Trump has gotten huge numbers of infrequent voters to the polls, twice. He's deeply unpopular but has mobilized a large, unprecedented coalition of Americans motivated by some combination of ignorance, avarice, and cruelty. It is hard to describe what he has as something other than charisma

I have a Grand Unified Theory of Recent Polling Errors
-there is a crucial population of people who occasionally vote, usually only in presidential elections, but don't pay attention to politics and never answer their phones

Good summary of why pollsters whiffed in VA and NJ. TLDR: electorate looked like 2017 when pollsters assumed it would look like 2024, plus Latino turnout exploded.

BTW, I would really like @consumerreports.org to watch this video and perhaps start breathing down the necks of those big companies for forcing everyone into using pre-dosed products.
