fpslem, w ‘Transformational’: how a California city launched America’s first hydrogen-powered passenger train

I posted this because I think this is absolutely silly. A hydrogen-powered train that runs on a low-volume 9-mile track? Why on earth couldn’t this just run on gantry-provided electric power? I guess it’s fine as an experimental trial system, but let’s not pretend that hydrogen is better than electric in basically every rail application imaginable.

Jumuta,

it’s also hilarious that the picture in the article shows overhead wires

the first hydrogen-powered, zero-emissions passenger train

That depends entirely on how the hydrogen is being produced: it’s an energy storage medium, not an energy source.

Though the onboard process does not directly emit greenhouse gases, the production processes to create hydrogen fuel in the US almost always do.

fpslem,

100% agree, this article glosses over that (and many other aspects) of this supposedly newfangled system.

usrtrv,

But what’s wrong with working in parallel? Develop hydrogen while the grid becoming greener. A traditional electric train has the same issue of being grid based.

Latuga17, w California’s new electric train makes for a shockingly better trip—we tried it

So glad that caltrain go ally has what would be considered normal in the rest of the world 🙄. But seriously this is a massive improvement and commuter rail systems should see this success and do this instead of trying to have battery powered trains and diesels that run under northeast corridor wires.

fpslem,

Agreed! I feel like Americans can’t imagine a future without seeing it somewhere in their home country. They travel to London or to Paris, enjoy the high-speed trains and the frequent metro service, and then come home and keep getting in their cars. So actually experiencing modern electric rail service (albeit not yet high-speed rail) in their own country is a big deal.

There’s a facebook group for that line, perhaps they could help you: www.facebook.com/groups/upbelvideresub/

Hey coding nerds, I know you’re nearby, do you think I’d be able to use tensorflow or something to identify an incoming train with this view?

Technoguyfication,

You could, but if this is taken from another window in the same building you’ll likely only get ~10 seconds of warning.

If you could put a couple cameras a mile or so down each direction on the track you could get an earlier warning system

yokonzo, (edited )

This is taken from my window, and I’m not sure how I feel about leaving expensive equipment out in a suburban area for anyone to pick up and run off with

usrtrv, w How do I learn a freight trains schedule?

There are groups out there that monitor train routes. And some publish to the Web.

In theory you could hook up an software defined radio and listen to train transponders yourself and give yourself a warning if one is nearby.

I don’t know what it’s like where you live, but as rule, who knows? There are scheduled trains which are notoriously unreliable, but also unscheduled trains. Basically whenever there is enough cargo to justify a train it gets put out on the tracks and they move it when they can. Caveat: this is for Canada and is largely based on info from some former neighbors who were conductors and brakemen.

My sympathy to your cats.

yokonzo, (edited )

So real shit they don’t track freight trains? That seems kind of inefficient if I’m honest.

Then again I’m not a train professional so what do I know

Freight is definitely tracked but not necessarily scheduled in regular intervals. This is true for both trains and ships. Like it costs so much and the world isn’t always that consistent.

But yeah like cp/cn/CSX/ns/BNSF etc all know what’s on their lines and where.

However these lines are fully private unlike aviation so there is no requirement to publically provide any data.

For planes position data doesn’t even come from the airline but a govt mandated transponder that communicates on public frequency on the aircraft and private websites use a network of recieving radios donated or not spread across the world to provide the public with a service they also try to profit off of. This doesn’t exist for trains as far as I know. And I don’t think for ships either.

Well that puts a wrinkle in my train heist.

DrBob,
@DrBob@lemmy.ca avatar

They track them, but they’re not all scheduled. If there is enough cargo there they put on a “special” and they will move it between the scheduled trains. Train scheduling and tracking is an art unto itself.

h3mlocke, w California’s new electric train makes for a shockingly better trip—we tried it

Ha! “Shocking” I get it!

Gieselbrecht, w California’s new electric train makes for a shockingly better trip—we tried it

It’s funny to read this article painting electric trains as a great novelty, when the majority of trains in western Europe (excluding certain island states) have been electric for decades. But good for california, sounds like a nice improvement!

XeroxCool,

Or that the Northeast Corridor (DC>Philly>NYC>Boston) is all electrified and has the fastest passenger train on the continent (Amtrak Acela can do 150mph, soon to be replaced with a 165mph variant that can do like +30 in turns). And that NJ Transit on that line (following US 1 and I-95) is electric along that massive population concentration. But yeah, good for California. I get it, running power is a really expensive project but at least this section goes back at least as far as the GG1 loco days.

ChicoSuave,

America is a petrostate that uses diesel and coal for most industrial purposes and trains have usually been used as cargo movers and not people movers, so they usually use diesel.

fpslem,

I just loved seeing electric rail referred to in a positive manner, and to see the benefits (speed! quiet! comfort! land use!) highlighted.

davel,
@davel@lemmy.ml avatar

Yeah it’s not very impressive, electrifying one commuter line, when China now has 45,000 km of high speed electric lines.

Repelle,

Yeah, I was really surprised. I would have assumed the vast majority of commuter rail was electric, it’s certainly been true for the rail I’ve taken.

Rentlar, w I have been seeing this smaller engine a lot recently

From the manufacturer’s website, appears to be a maintenance of way (railroad and ballast maintenance) vehicle.

nokturne213,

Thanks. I was going to look it up today. I am going to try and build a LEGO version of it. I was unsure if herzog was the manufacturer or the operator. But I figured either was it was a good place to start.

TheOubliette, w I have been seeing this smaller engine a lot recently

It’s very cute

yokonzo, w I have been seeing this smaller engine a lot recently

I thought this was the default one. IDK where I live in Illinois I see this one a lot

nokturne213,

This is about 2/3rds of the size of the standard BNSF engines here in NM.

nokturne213, w Inside America’s First High Speed Rail

I would love a train from Albuquerque to Denver. Currently for that trip you have to go through Chicago.

espentan,

Holy cow, now that’s what I call a detour.

mercano, w Mt Washington Cog, 150 year old steam engine
@mercano@lemmy.world avatar

If you go, pay attention to the schedule. They still run one steam loco per day, so two round trips, but most runs up and down the mountain are powered by the biodiesel fleet. The cog railroad dieselized to reduce operational & maintenance costs, and to reduce emissions. Parts for the steamers were getting hard to source, and while the coal smoke coming out of the steam locomotive makes for good photos, it’s not always the best image, if you know what I mean.

Lost_My_Mind, w How much does it cost to build a shortline railroad?

Not that I have millions of dollars lying around

Guys, he’s lying. He TOTALLY has millions laying around.
