Why is transportation board called "n"? What does it stand for?

It's probably a repurposed board from when 4chan was reorganized over criminal liability issues like /g/ and /i/. The original /g/ was for guro and the original /i/ board was for invasions and raids. Moot ended up having to change these boards and some others to new work safe topics around the time that the feds came calling about /b/.
>>
>>1980586
the first board to be called /n/ had as its topic Trains. But that was actually the second board with that topic, the first being /r/ (added to test only)
/n/ then became Nature, which then became /an/. /n/ then became News, and then finally that board was scrapped and the /n/ name was used for the transportation board, likely as a callback to the original /n/. Why the original /n/ used it I don't know, but it's probably >>1980782

Totally random late night thoughts

At the current known speed of travel throughout space (maybe not max) but at the speed the JSWT (telescope) reached the L2 zone in space. It would take 7291 generations of astronaut to reach some planet they believe has a civilization on it meaning it would take 324.7 Million Kg's of food for the entire journey assuming only 1 breeding pair or humans at any one time (inbred as fuck)

583333.3 years assuming 80 year lifespan which isn't including the 20 year overlap having 4 people on board whilst children are brought up to speed and left at age 20 by their dying parents. They would they be dead because the amount of inbreeding required at those levels would make them so fucking retarded they would forget how to breathe.
In closing. Close to 700,000 years worth of life, 389.7 Million Kg of food (including the 20 year overlap) is what would be required to make it to that planet

We aren't making it to any other civlized planets before our finite resources are depleted. Humanity is fucked unless we come leaps and bounds in space travel and shielding technology.

You can theoretically accelerate up to in excess of 99% of C, problem as you described is deceleration, but having a civilization seeding ship having just enough mass to reduce the speed from 2% of C to a stable entry into a system and enough to build up a laser network to decelerate later waves is well within the real of what can be done, like with many technologies the physical ability to produce such technology exists today with the issue being the economics of doing it at present.

the same greenhouse effect that we are using to boil Earth to death could be used to terraform Mars. it would be slow and expensive, but it is doable.

the fun thing about Venus is that a pressure vessel with human habitable atmosphere in it would be buoyant in Venetian atmosphere. we could build the star wars cloud cities relatively more affordably.

why didn't doc brown's time-traveling delorian leave him stranded in space? i don't believe it was ever stated that his machine accounted for the position of the earth in any specific time. the position of the earth in space isn't static, nor is the sun or anything else right? so if you took your starting position as a fixed point in space, your destination will most likely be somewhere in the interplanetary void rather than 'where i was on earth but 30 years ago' or whatever.

the instant of transmission is the fixed point in space where you hit 88 and punch back to 1955, except the earth in 1955 isn't in the same spot as the earth in 1985 and now you're just floating there in outer space.

I don't think they were ever considered futuristic. The idea has been around since the early 1900s or possibly even before, but it was always obvious that the technology sort of sucks for anything beyond a few niche applications. They never took off as a practical form of *mass* transportation because with single track rail, switching becomes a lot more complicated and annoying to figure out. However, that's also why they did work in some applications where they only needed a single track with most switching just being to go into maintenance or storage sidings. They really just don't have any purpose when normal rail exists, so they never took off. Why use a monorail when 2 rails works and is superior?

Airports and amusement parks sometimes have them and they work there. A few world expositions did too - pic related, it's the one Brisbane, Australia in 1988. These are usually temporary though. Okinawa and Chongqing are examples of cities with pretty complex monorail systems, but they're also simple in terms of the route they take.

Tl;dr they don't really serve a purpose when regular rail does the exact same thing. Maybe the only extremely unique use cases would be like...underground mining or similar operations, where suspending rails is easier.
>>

Mine monorails are pretty based btw. Just rare, because similarly why spend all that money on installing something like that in a mine which is finite, when you can just drive trucks and shit. The joke on The Simpsons is basically this. A snakeoil salesman came along, sold them on this cool new idea and it turned out to be a pointless waste of money, like basically all monorails.

I know this is a meme but this is actually a huge contributing factor. Everyone points to how absurd it is that a city as big as Little Rock has ZERO intercity bus connections, but the fact of the matter is that's because the city and the adjacent cities KICKED OUT greyhound, because none of them wanted stops in their cities for this exact reason. As service gets worse the people who take it are more and more desperate which makes the service less and less attractive. National intercity bus service is in a death spiral it will never leave from. I think the best bet is small, regional, public intercity systems and just hoping to god that some small towns overlap between two systems and you can transfer between them there.

This thread is for talking about railways, and things related to railways, in the United Kingdom of Great Britain and Northern Ireland. Trips, tracks, tickets, trains and stations, they're all good - making up rules is boring so let's just be normal. Questions are, of course, most welcome.

If you feel like travelling, head over to National Rail Enquiries (nationalrail.co.uk/); tell it where you're leaving from and where you're going to, and it'll tell you how you're going to get there; then it'll hand you over to a train operator to buy a ticket. The golden rule is that it doesn't matter which train operator you buy a ticket from, as they'll all sell you a ticket from anywhere to anywhere, for the same price. If you're a visitor from overseas, your best option is probably Trainline (thetrainline.com/) - they charge a booking fee on top of the ticket price, but they'll accept just about any payment card. There's also trip.com/, who are apparently a 'thing' with overseas students: I've not used these myself, so please speak up with any thoughts.

Here's a few links:
~The Man in Seat 61 (seat61.com/) - easily the best rail travel resource out there.
~Geoff Marshall (youtube.com/@geofftech2) - Likes trains. Mostly harmless.
~A Visual History of Railway Rolling Stock in Great Britain (gaelan.me/br-stock/)
~Realtimetrains (realtimetrains.co.uk/) - live train timetables: ideal for keeping on top of ETAs and platforms.
~TIGER (tiger.worldline.global/home/) - live station departure boards.
~Traksy (traksy.uk/live/) - live signalling information.
~Openrailwaymap (openrailwaymap.org/) - railway infrastructure, mapped.

What's happening?

DC has a lot of advantages compared to AC at lower voltages. There's no reactive forces and no skin effect to worry about, which will reduce transmission efficiency. These losses become more prominent at lower voltages and higher currents.

So everything with a 3rd rail or otherwise on a lower voltage can transmit more power with DC than at the same voltage with AC power.
>>
>>1985412
>Why are there so many different voltages, AC/DC, and frequencies used in rail?

History. Control of the rotational speed of an alternating current motor is very hard without the ability to control frequency. Thus earliest electrification systems were either DC ( 1.5kV, or 3kV, usually ) or low-frequency AC, to be able to use brushed AC motors ( 16 2/3 hz, usually ). This is why MILW wires were DC.

Since the mid 50ties and certainly, since 70ties of the previous century wide adoption of solid-state power electronics made frequency control pretty straightforward, thus newer systems use straight 25kV 50hz wires.

Nowadays - it is 25kV/50hz for everybody unless a legacy system is involved. If you want to know more - apart from being a railhead, I am also formally educated in power electronics and electric technology in general.

The single-prop aircraft does want to spin the opposite way the prop spins. In such aircraft with high-powered engines (e.g. WW2 fighter planes), this is literally something the pilot has to fight against until the aircraft is flying fast enough. Cocky trainee pilots in WW2 used to wipe out on the regular the first time they got to fly a military fighter as opposed to a low-powered trainer plane.
Once the aircraft is going fast though, the air flowing over the wings resists the rotational force better (stick your hand out of a moving car window, and it resists harder than the air at rest).

Walking is more efficient at low weights (even including the weight of a bicycle) and as weight increases, bicycles hit an upper limit where they require more adaptations to function.
