For people not familiar with the matter: any tram line I'm aware of globally works in so-called "line-of-sight", i.e. it's 100% manually operated by the driver with some protection for single track and switches
None use PTO signaling (i.e. that enforce max speed), except on off-street sections

We’ve blown hundreds of millions on a “high performance” signalling system meant for separated railways, that, on a streetcar, simply imposes a more conservative operating regime. Why?
- “Safety never stops so we need the safest signalling ever!”
- “LRT is rapid transit, just like the subway!”

The regulated transport era was not some function of a halcyon socialist past, but an absolute necessity given the state of technology.
Booking a trip took 1-4 DAYS. There was *no practical way* for anyone to compare unregulated fares and availability. Without choice regulation was required.

Wasn't just airline travel being much cheaper today than in the past. For NYC to Chicago in 1949, Amtrak is less than half of what the PRR charged in coach and about 2/3rds the cost with a sleeper.
This is what ppl who think the 50s were a golden age forget about the real cost of goods.

Can we PLEASE stop citing Amtrak's generic delay codes and calling it reporting? Ever since they made those damn codes public its created a torrent of bad reporting and bad peanut gallery commentary. Find the ppl with the radio scanners and get the info from them

There's a movement on the right to label fascism as left wing for the exact same reason. 😅
One of the most damaging things that morons like Chomsky have done was to take the history of communist tyranny, and proclaim:
"Actually, they were rightwing, because they did bad things. And we are the good guys, because we are leftwing."
Thoughts so deep, they could fill another mass grave.

I just saw a stripped SEPTA M-4 car on a flatbed trailer heading northbound on US 13 in Bristol.

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. 🙄
