There are jackass cyclists like there are jackass motorists and jackass pedestrians. Yet we get the hate because we’re trying to be both economically and environmentally efficient while getting to places as soon as possible?

The numbers you give paint an incomplete picture.
There's a linear component and a component proportional to power when it comes to drivetrain losses. It follows that only at low power you get bad efficiency, literally when it doesn't matter. At 300W the picture is different.
According to data I have a singlespeed with a dead straight chain is roughly wastes 6W/200W or is 97% efficient and interestingly does not get much worse if power drops to 50W only, where it wastes ~1.6W/50W.
Deraileurs of course depend on gear selection, just like the single speed depends on chainring and cog size but additionally cross chaining. On average 8W/200W or 4W/50W (!).
Alfine 11 reaches very close to the deraileur systems efficiency in gear 1 and gradually worsens towards 11, where 26W/200W go to shit. 5.5W/50W in first and 11W/50 in 11th gear.
This makes the Alfine 11 perform quite well, it certainly benefits from the chainline. Even more so you get the best efficiency when it matters: High wattage, low gear, climbing loaded in a headwind. We are talking about a difference of 1 or 2 W in the lower gears. This is under lab conditions. Meanwhile in the real world, aside from the chains condition, a sealed unit will perform consistently over weeks of travel and 1000s of km without regular care (something I at least can not realistically or dont want to provide on long trips).
So, a couple of watts:
The difference is on par with a dirty chain (~4W).
At average pace this difference is equivalent to ~0.2 km/h.
It's equivalent to half the difference between a butyl and either a latex tube or tubeless setup (~ 8W for 2 wheels).
It's a fraction of what wrong clothes, more upright position, wrong tire pressure etc. cost you or to put a nunber on it: The difference is as low as 2% which at speed translates to 0.007% difference.
Personally I love deraileur bikes but for daily, business and travel IGH wins.

An entry level new bike, that is agreeable to ride, not dragged down by antiquated standards like QR, that you won't regret buying, nor immediately feel the urge to swap out half the components because of cut corners, cost approximately USD $1500 at standard retail prices as of late 2024, give or take a few hundred (depending on the finer details).

Now, the prices are going to go up by at least 20%, and the smaller independent brands are going to go under as only the largest players will have the spare cash to ride out the sudden loss of consumer confidence. The most interesting and original bike products will simply disappear from the market permanently until the next wave of prosperity (which may be entirely concentrated somewhere far away and foreign, so that only the wealthiest of your peers will be able to import and use such goods).

How does that make /n/ feel?

That's like saying a heart attack is the circulatory system correcting itself

An actually efficient system would have enough liquidity where mass anything would be unheard of.

But we've got it set up so that your health care and retirement security are tied to not taking the risk of moving to another job, so people hang on far too long and then get purged, and we get growing masses of permanent underclass living in tent cities and you people will be like "just buy more money poorfag commie" while supporting infinite giebs for the people who caused it

The end of ebike terrorism is in sight. Let's not count our chickens before they hatch, but I'm tentatively feeling hopefully about this. During the time that the last thread was up, hundreds of people were killed by ebike fires. We need to put a stop to this. I just hope they make sure to add prison time for people caught with unlicensed ebikes.

I've always been a big fan of the Canadian Pacific C-Liners and their 38D 8-1/8 opposed piston engine. I haven't found a book that goes into their design and construction and inspiration, and trials and tribulations. I do have "Constructed in Kingston" but while detailed about construction it doesn't really go into it's design. The best I've found is the 2-part series in Trains magazine (March-April 1987) which I bought when it came out. I bought a couple actually. The author worked at F-M and he goes into decent detail on the design and concept.

If anyone knows of any other book, let me know because as far as I know I have every book there is on them.

Due to a labor union strike the busiest train system in North America is completely shut down

https://longisland.news12.com/2026/05/17/lirr-service-suspended-on-day-one-of-historic-strike/4loTlXtTUwBPvTZquC1dIh

LIRR workers in the striking unions have a median/average salary around $131,000–$136,000 (highest-paid railroad workers in the U.S.), with total compensation often exceeding $200,000 including benefits. Many top earners make over $250k with overtime. https://www.newsday.com/long-island/transportation/lirr-pay-highest-wages-deovhmtu

Planes don't need parachutes, they can glide. Using a parachute gives you far less control than simply being able to perform an engine-out landing. Imagine if you panicked and threw the parachute only to find out here are power lines directly underneath you and there's literally nothing you can do about it. If you simply looked for a proper landing area within your glide range instead you could've avoided such a scenario. A parachute if anything is just the manufacturer admitting their plane is shit and that they don't trust the engine not to die in a bad circumstance.

>>
>>2078057
People discuss the costs all the time. For passenger use, trains have a niche where they make sense. Problems come in when train obsessives want to force everyone into that niche. Private companies can never work because they can't acquire the required right-of-way without making use of the government's power of eminent domain. For most, we already have done better with the Interstate system and plentiful airports. No idea what you mean by your last question, though I suspect that answer is still the need for eminent domain.

Steam is having a train game sale for the next week and I figured this would be a good place to ask for recommendations.

I really liked Truck Sim and I played a similar game called Train Life: A railway sim but that game has been long abandoned.

Are there any other recommendations for train games? I prefer the more simple/arcade like sims where you don't really have to mess to much with the controls or shunting. I also own Derail Valley but I don't know it's not really clicking for me, though I think I need to give it another shot.

The only way you can have RPM and speed measured by the same dial is if the model is locked to a specific wheel diameter. Different wheel diameters have different relationships between RPM and speed, and you need completely different gauge markings.
If it didn't claim to display RPM on the gauge, I might not have noticed, but it's 100% non-adjustable/tunable.
>5,000 m / hr divided by (400 RPM times 60 minutes in an hour) = 2083 mm per revolution
>2083 mm per revolution = 66.3 cm wheel diameter or about 26 and 1/8th inches
Hope that exactly matches your bicycle and you don't care about things like tire wear or inflation pressure.
>>
>>2078014
i don't care about rpm if it's the wheel's rpm. now if it can somehow measure the pedals's rpm (cadence) that's a different story, it would be like the rpm gauge in a car.
>>
>>2078015
im like 90% sure these are just third shift/b-grade qa fail units off of motorcycles

they probably work fine but after looking into them myself a few weeks ago it's a lot of cabling and weirdness that's probably not worth the SOVL of a mechanical gauge

if you dont want a battery operated thing you could try to figure out a stator/rotor setup to do it without needing a battery like engines use for their timing and tach but that might lose you enough energy to magnets that you can feel it

>>2078014
good models have a tuning screw and you can probably just replace the faceplate with the actual numbers on it. it should always measure RPM accurately (that is what it is actually measuring, with a little spring loaded clutch thingy right at the axle) but you can figure out that function for RPM to actual wheel speed and sharpie in new numbers on a piece of paper you stick to it

>tire wear
you're losing max like 2.99mm before your tire is unserviceable junk
>inflation
just keep your tires inflated??
