What are the considerations needed to make between choosing a locomotive or MU to power a train?I know passenger trains in Europe tend to be MU but freight is always locomotive hauled.
>>1992346>Jacobs bogiesmain downside is that cars sharing a bogie are a bitch to seperate, while the whole point of using sperate cars instead of an integrated multiple-unit design is to be flexible in their combination.Btw, I've seen similar designs (not sure if technically a jacobs bogie or if there's special terms for it) in car-transporters and container train cars, making two-car consists with 3 or 6 axles respectively.
>>1992370I've always heard them referred to simply as articulated cars, jacobs bogie I only hear in reference to passenger equipment. Articulated autoracks are two cars, articulated well cars can be up to five cars, at least in US. 3 and 5 car articulated well cars are very common. I don't see it as much with autoracks.
>>1992346>Why aren't Jacobs bogies more of a thing with coaches?When going through the trouble of Jacob's bogies, it makes no sense to have them on 'dumb' coaches. If you want to keep the axle load in check, the middle sections will get about half the capacity of a full coach - or even less when vestibules are considered. Jacobs bogies are also troublesome to rearrange the train, if it's not an EMU, then why limit the inherent flexibility of the wagon consist?This is why they are popular on EMUS, but not traditional coaches.However, this does not mean there weren't any. A famous example was British Silver Jubilee coaches originally pulled by A4 Pacifics. Pic rel is a German-made four-car set of Polish railway's double deckers which were phased out a few years ago. Those have three axle Jacobs bogies and were being used as two, three and four car sets. Romania, I think still uses these.
>>1992370>>1992472I'm only asking as it seems like most passenger trans are made of coach sets where you have a number of them coupled together for a long period.The axle loading doesn't shoot up nearly as fast as you might think, a coach is an air-filled with some seats, racks, etc inside. Also, each section in an articulated set is shorter to reduce overhang inside the curves, but there's a reduction in the number of bogies over the whole train length.The overall weight of the train goes down too, as each bogie is heavy. Maybe ~6 tons each for a lightweight design, which adds up. E.g. for a train of 8 coaches that could be a full coach's weight.I get that this is probably more of a consideration where acceleration/ high speed performance is needed. As you say, for Amtrak and other long distance/slower services the consideration changes to reliability and easy maintenance.
>>1992460Germany definitely has some 3 axle two car autoracks, while the container cars have 3 bogies of two axles instead due to weight.>>1992558Indeed those consists usually remain as is throughout the day, however from a maintenance standpoint single cars are a lot easier to handle given the facilites used for that.Single cars can just be decoupled and then spread throughout the maintenance yard with these funny side-swiching bridges they use, while consists with jacobs bogies can only be handled in their full length. Having properly seperate cars also allows all sorts of switching around when one is due for a service or repair. Up to just running the train without it.For serious acceleration it's almost always just an EMU anyways, due to better ratio of tractive weight to total weight.

America has globally, objectively low commute times. And generally the more public transit usage and walking there is the longer the commute.
>>1995985>spending a quarter of your waking life driving to workYep, that's the European way, wasting your life for the 'environment' and smelling armpits on the bus while Americans have quick and easy commutes using cars.Also owning a car in a normal country like USA isn't expensive, since you don't get raped by insurance, taxes and fuel prices.>Sounds like great arguments for building more housing adjacent to metro stations and increasing bus and train frequencies!Yes retard, let's pack everyone extremely densely into little 3x3m boxes so their masters can get them to work as cheaply and efficiently as possible. Having your own house with a garden and a garage? No thank you, I prefer listening to crying children of my next wall neighbors. Fuck quality of living, that's for Americans.
>>1995989Anon, you really should value your time higher. Every minute spent driving is a minute you could have been exercising, reading, studying, or catching some Zs. Or hell, just shitposting here. Instead you willingly pack yourself into a car for an hour each day, just to spend 3 more hours making the money to pay your car payment, insurance, gas, and repairs before you start making money for food, rent, hobbies, vacations, etc. You're sitting here posting about your commute as if that's the only factor in quality of life.>Also owning a car in a normal country like USA isn't expensive, since you don't get raped by insurance, taxes and fuel prices.Hilariously wrong, median used cars cost around $27k, median new cars around $46k. That's not cheap, and insurance has skyrocketed in the past several years because Americans are driving more recklessly than ever before and cars are getting more and more expensive to repair. My own insurance on a 5 year old hybrid sedan that I own is $2600/year despite a stellar driving record because of the sheer number of idiots on the road.>15 minute conspiracy theoriesMeds. Now.
>>1995970if only we could just build them in a way that covers a large enough portion of where people live so that a station isn't too far away, even in the suburbs with larger homes
>>1995994>Anon, you really should value your time higher.I do, that's why I use a car instead of wasting time on public transportation.>median used cars cost around $27k,so? I bought mine for 5k. You can go way cheaper but I wanted something with over 250hp.>conspiracy theoriesArea 51 was a conspiracy theory, doesn't make it untrue. There isn't even a theory, you can just listen to what they say the want to do to you.
>>1996042Still way worse than a car. Too much walking and waiting for a train.

What the fuck is wrong with these mongoloid slackers? They completely underschedule longhaul trains everywhere outside the NEC so almost no one can use them for shorter trips and then wonder why ridership is in the shitter. Each route should be minimum 3x a day per direction.
>>1994046>JRBuilt by the government then privatized>if Amtrak could leverage the sameDoubt they're legally permitted to and even if they could, the chance to buy cheap land remotely close to city centers disappeared decades ago
How is Amtrak going to get the line reservations when they're competing with coal and bulk commodities for rail time?
>>1992023Long-haul routes are kind of a special thing, like preserving a traditional way of travel without too much practical use.But they could just run a bunch of regional lines between major cities more frequently, maybe buy some smaller DMUs for that. I'm talking journeys that are maybe up to 4-5 hours, start with two or three trains a day. That wouldn't be very expensive and it might get people to use trains more regularly. They could also work as feeders for the longer lines.
>>1992023Americans like their cars.
>>1995958Americans like trains, too.

>>1976443This guy is the scooter "e-bike" trash on why i hate the chinese throttle garbage. This dude got some piece of shit off amazon and doesn't peddle just throttle controls everywhere claiming he deserves the bike lanes going 30+MPH on bike lanes and sidewalks
>>1975554Cheapest thing with the quickest charging and regen braking? I really want to make the world flat.
>>1995777So at minimum, you want pedal assist only?
>>1995857Yes, and all UL certified. That would be a good start. I mean come on Chinese seem to have nailed the fat america oh so well, since they sell the vast majority of cheap fire hazard throttle assist bikes. Also really the whole class two seems like a stupid category. It wont address people trying to mod their bikes to remove the limited but its a good starting point.
>>1995904That would be my next comment/question: regulation is mostly a dream. But not to be evasive, it would keep your average dummy from hurting most people. Probably a net positive. But I don't want anything to hinder a car replacement. First step of that is stay just below the line of regulation.
What is the most pleasurable airport to be a passenger in?Pic unrelated.
Do any of you have experience working a grunt job at an airport? DTW is nearby, and I've always liked the idea of seeing/hearing the commotion of machines and people on their missions while calmly stocking a snack shelf. Almost like an omnipotent observer.

>>1995845No job. Just ethical consumerism. Like cars, these shits should be modularized/standardized as a sad nesscary part of the world to make them as cheap as possible. The Bolt just needs a dual motor kit (doubles milage to 30)/redesign to carry lower slung batteries.

I really like planes, especially the BOOM Overture. Concorde, 747, 225, A380, and C-17. What planes do you like? :D

>>1991775Important to note: the gradient here. White in purpedicular sunshine: 120FBlack: 140FThe answer is double hull and/or insulation, even propane powered refrigeration. All beats the greenhouse on wheels if a car.
>>1995848>White in purpedicular sunshine: 120F>Black: 140FWhere did you get those numbers? On picture range is from 31.1°C to 45.8°C (88 F to 114 F).I can't find the link to the full study though to see what is the ambient temperature.I think insulation might do more harm, because the major source of heat is still the body doing the work. And you have to remove that heat. Insulation is good only if you actually have some sort of air conditioning installed.Vented double hull might work. The outer hull stops the sun and heats up because of that, inner hull is heated up by body heat and the air between both hulls circulates and cools down both inner and outer hull. >propane powered refrigerationDo you know where to get it? I cant' seem to find anything useful.
>cycling on sidewalks is... le misdemeanor! >you should drive on the streets with a speed limit under 50 km/hname a more braindead law than this, jesus fucking christ99% of people riding bicycles do it all their lifeI am convinced the only reason this law exists is so that the ONE time some cop(s) with nothing better to do blocks your path, they can milk you for fines and report all your personal info to the big brother systemthe whole fucking point of a bicycle is that you are not a car and that you can go places cars cannot, but carbrained lawyers the want to regulate the shit out of it for some reason, even in le walkable non-carbrained EU cityfuck I'm so pissed off right now
