I never have a concern about safety when riding on trains. My grandfather worked for almost 50 years on the New York Central, then on the Pennsylvania then BOTH when they combined in to Penn-Central! He was a brakeman on freights. I knew how seriously the roads took safety (even when those roads were "bleeding" money) I live in Pittsburgh and when I want to go to NYC, (Have family in Brooklyn) It's ALWAYS by rail! Yeah, a plane IS faster (I'd spend as much time GETTING to the airport as the "wheels -up" time of the flight!) Airports are a PITA, generally. and you have to spend BIG BUX on taxis to get out and into the respective "downtowns". On Amtrak, I leave Downtown Pittsburgh and I end up in Manhattan! (Then, I have subway access to the whole city!) Sure it's a 9Hr ride. But the train is comfy , so sleeping is an option! I just plan my trips to accommodate. This holds true in the OTHER direction as the few times I went to Chicago. I also ride Amtrak a few times a year to Sandusky, OH to visit my daughter. The ONLY time i fly is when going to the West Coast (rare occurrence).

Oh shit, a naturally voiced infographic video?! Thats rare!

The Dutch national railway NS uses 100 % renewable windpower. The majority of railway lines have been electrified. The Netherlands is small country (seize of Vermont), with a dense railway network.

This whole thing about climate change, carbon emissions, net zero is a big scam

Makes sense to me! There's no real reason why electrification of railways can't happen even without overhead or third rail power when you can harness regen braking and batteries to do a lot of the work... And yes fast-charging is certainly possible at sidings and station sites...

No shit Sherlock

Thank you for this, well done. Technology helps these concepts along. A company that makes graphene supercapacitors has them installed in heavy trucks and passenger trains. The capacitor can take the current from braking instantly and efficiently and store it for the next cycle of acceleration. The heat energy manifested during braking for these heavy trains/trucks is significant and until now has been wasted. Large companies have recognized this "waste" and can convert it to "operational cost savings."

Captain obvious !

I wonder if some kind of modular barge that can be transported via truck or rail upstream would ever be developed

A great idea turned into reality.

Calculations could include the fact that railroad box cars weigh quite a bit more than a tractor trailer for the same contents. So they are still much more efficient but not the entire 24x.

Don’t like the AI voice

That is awesome!

1:38 there are no cement roadways. They are made out of concrete. My father, an architect, explained when I was seven years old that “cement comes in bags“.

Hello? They've done in for real in plenty of movies. We didn't always have CGI.

I have studied railroads for 50 years. When I tell people that the United States has the most efficient rail system in the world - our freight rail system - they don't believe it. Our freight trains are also super-efficient because of diesel-electric locomotive power, which combines the force of diesel with the finesse of electric driving of the wheels which is needed, for instance, to get a 10,000 ton coal train moving from a dead stop with very slow turning of the wheels (imagine trying to do that with a clutch). We need freight trains for heavy loads and for long-distance hauls. Trucks can fill in the shorter routes at each end. They are a great system when working together.

Finally someone says this!

Just one oz?

It depends. Truck is more efficient for last mile and first mile because it can reach almost every part of the cities. And the plane is more efficient for long distance because it is faster and cheaper than train. If we talk about most efficient way to transport cargo, ship is the most efficient, and then high-occupancy train. Ship, train, truck, and plane complement each other. Without trucks, trains operation cost wouldn't be efficient. Similarly, without planes, packages that need to be delivered quickly wouldn't reach their destinations on time.

Hi

also these guys in canada: th-cam.com/video/ndADHCmv9H8/w-d-xo.html

you should tell tom cruise because they actually did run on top of a train and jump from car to car in dead reckoning: th-cam.com/video/n7Bcsh9Dh5o/w-d-xo.html

It is make-believe dude.

When Kevin James first started doing stand-up as Kevin james, it didn't always go so well. One night, he was sitting at the bar after a particularly brutal gig, when a buddy of his came up and asked the bartender how he'd done. "Bombed," the fellow replied. "James bombed."

Rest in peace to the AI narrator and possibly AI video. 🕊️🕊️

I don't fly for a number of reasons.

As someone who specializes in physics and aerodynamics... Your statements are technically correct but your explanations are definitely not. Energy loss in wheels is not due to friction. When a wheel contacts a rolling surface the point of contact doesn't move. That means it's the static coefficient of friction. If you're using kinetic friction on a wheel it means your wheel is slipping. Static friction doesn't cost energy... Where you lose energy in a wheel is due to structural defamation of the wheel at the point of contact. That structural defamation and reformation causes heating, and it's that heating that represents your loss of energy. Same exact thing with the truck tire. As for the aerodynamics... I'm not going to touch that, but... 🤨 Now when it comes to gravity, the gravity doesn't help the train or the truck one way or another. Where the train has an advantage is in its mass. A train has so much mass that it's able to store gravitational potential energy and convert it back and forth between potential and kinetic energy very efficiently. And because trains are so long and the links between them are both tensile and compressive a train is effectively able to average out the gravitational potential energy along its length. This is why regenerative braking works better for heavy objects than for small things like bikes.

What about Ocean Liners they’re more comparable than Jets since they use horse power and Not thrust like that of jets

Trains are indeed more efficient, what I don't get is why they are so expensive (train ticket vs bus ticket or airplane ticket)

Also three locomotives can transport about 120 rail cars. How many transport trucks would that take to move same. How many people die each year in truck crashes compared to rail related deaths.

if this is true railways would be everywhere they are not they all have been ripped up to favour roads and trucks

Correction: Friction does not determine efficiency. In fact, high friction is desired for any vehicle that rolls on wheels. The thing that makes trains so much more efficient than trucks is their extremely low rolling resistance.

Can someone send this video to elon musk?

Even ships too

Very well said, excellent video. 👏👏

The reason is train dont get stuck in traffic but instead train creates the traffic lol

Let's gooooo 🔥🔥🔥🔥

noice

Love these animations!

Seems China is in same position as USA was in 1800s

"You died of dysentery"

Yup, we British did it first!

Shoutout to all of the friendly Calgarians who chatted with us. 🙌

Awesome job!

Great instructor, I’m sure he has instilled good habits in all the professionals he’s trained!

I love the way he was talking

Dude sounds like David Lee Roth

😍
