I would argue transit and active mobility investments tied into stopping local government from highway expansion is an equal priority.

"I've been radicalized on bicycle and pedestrian safety."

Ah yes 4 unit builds definitely don’t belong in the suburbs. LAs dingbats would like a work

Sure but that falls apart when you look at his history in local government

Becerra and Steyer are both “fine” based on what I know. Steyer has bolder ideas but no political experience

Porters legislative attempts are far too anti transit or local control focused

Mahan struggles on housing and transit when you stop listening to campaign rhetoric and look at their record

There’s no strong data to support their position and they’ve ran out of just trust us as their arguments get weaker.
I was hoping for 6 stories and expecting 5, looks like we will get 4.

Meanwhile, Metro wants cut $5M from Metrolink operations, which will lead to service cuts that put more cars onto these freeways. Priorities...

Feds have rules on where aviation fuel tax can go to, right now that’s only supporting airports or a state aviation program. Goes back to the late 80s

given airports can impose landing and takeoff fees I’d be curious if the state can force every airport to charge commercial flights 5-10$ per seat and direct that money elsewhere.

Add "farmers in the American West whose farms are only viable because they are given incredibly scarce water resources for 5 cents on the dollar" to the car dealers and realtors — destructive, unproductive conservative groups that we need to reduce the influence of when we're back in power.

Key system took over part of their routes in 1940 and combined them with their own.
sfstreetcars.co is a good interactive map

Budds carshell design even on the Metroliner trying to copy a plane was fine. The issue was they repeatedly struggled with integration and sub contractors.

Texas cycling community grieving after Paralympian's death "Find some good roads to ride up there....hope the wind is always at your back."

Another senseless traffic death.

Paralympics champion Dory Selinger, who lost a leg in 1993 when a group he was riding with struck intentionally by a driver, was killed yesterday while riding his bike.

Appreciate this discussion of NFPA 130 here. The deferral to the fire service in each jurisdiction creates really bad incentives for cost control and risk.

How California transit operators and institutions understand transit

Happy tax day! Shout out to taxes, the cornerstone of a functional and equitable society, and in particular the often-maligned but extremely important property and gas taxes.

Given the likely time difference I’m not sure knowing direction would change much
They could probably provide that as a non vital output on current equipment

800+ railcars seems short. I was expecting 1200+ for the first round but I assume there’s lots of options available

Amtrak may include some on all LD trains in the future and based on the distance/hours expected on the train you’ll get assigned a different car and seat.

Curious what you think direction would add?

Yep looking at Siemens GCP3000/4000 the unit does not output direction to the preemption circuits.

Looking at this from a road signals perspective?
The crossing gate knows which approach was touched and based on that knows direction. It’s also how it releases the crossing gate before the trains off the opposite approach.
After some videos?

We don’t need PTC data for direction. It can be used for speed where approach circuits aren’t long enough

Approaches can be simple do we detect a train but for the US it’s quite common to have a constant speed predictor which also provides direction. Sometimes the trains can talk to crossings directly but that’s generally limited to 90mph+
Approaches will time out if the train doesn’t reach the island

Standard railroad crossings have 3 segments for detecting trains. Approach-Island-Approach. Approaches give the gates and traffic signal interrupts 30s+ at the fastest mainline speed. Once a train hits the island gates will remain down.

That doesn’t work for services that use a cab car which is all of Amtrak California

from where?
Amtrak can't spare superliners and we are short across the state.

If they give up checked baggage completely they can modify the first floor of the cab to be all bike space
