This stuff is ancient but I hope that it wasn't posted here before:

The construction of the Japanese Shinkanzen high-speed rails, form 1964.
https://www.youtube.com/watch?v=iYjFOYLAtoE


Both the footage and the tempo if that of the '60s, so do NOT expect some twitch footage and on point editing.
But, I think you all would appreciate it, or - at least - should see this!

ps: use auto-subtitles. While at some point it it definitely an 'eh', it is better than nothing.

Why do they only make documentaries about economically-sound train lines where everything went right?

if you're talking about "it's all so tiresome" that was a road building project iirc

Today, Bay Area Rapid Transit formally retired the last of its original rolling stock that had been in service since the system opened in 1972. The occasion was marked by speeches from BART officials and a farewell excursion between McArthur and Fremont (where the very first train had run on September 11, 1972). I was there and rode the last train.

Spring has started in the warmer climates and the worst snow is behind us.

Did anybody pick up any cool clothes to wear on the bike? A new jersey is 15 bucks on Ali. High fashion stuff like Syn and Pas normal have hipster cred. Vintage 80s throwbacks are in. Everyone has figured out taint pads rule even if sewn into 'tactical' mtb shorts.

It's never been cheaper to look good. What is your bike style and what are you doing in 2025 to make the scene?

I've been riding with the cheapest 155gr/m2 merino shirt from decathlon 5 years now, it's great and was like 15 euros, so a week later got 2 more. using them all year, rinsing with water every now and then and washing in washing machine every few months. they also have merino jerseys but their front is too short for normal shorts, gotta use bibshorts

>That cylinder is a mass dampener also known as a J dampener in physics.The purpose is to neutralize high frequency low amplitude oscillations.Mass dampeners are currently used in Moto GP and were banned in F1 in the mid 2000s.The mass dampener can also be placed on the fork,above the bottom bracket and as shown on the rear swing arm/triangle on a full suspension bike.
have these been used on road bikes yet? i have a stiff track bike fixie, anything that could improve performance or comfort would interest me. i haven't paid attention to bike stuff lately so idk if it has been mentioned on GCN/GMBN yet. GCN has done a lot of videos on tire pressure so i could see them experimenting with tuned mass dampers.

>>2027655
nothing is infinitely stiff, you can see when a bike is being pedaled on a turbo trainer that it flexes with the bottom bracket moving from side to side and it's not a problem. it's not common for a frame to fail unless there was a manufacturing defect or you crashed it. an aluminium frame has a limited lifespan in theory but will probably last for decades without catastrophic failure even with a lot of high mileage riding.

This one so much. When I picked up someone from our main station I waited upstairs until I actually see the train because otherwise they WILL change tracks last second.
Due to common late arrivals it's more fun to meet in a cafe or store upstairs anyway.

I went to a train station where hostile architecture wasn't used once.
I ended up rolling my luggage through a puddle of piss. Would not do it again, plus the station stank like rancid body odor.
It was Philadelphia, the Market East SEPTA station, in case you're wondering.

3v Sunrace Sturneys are bad bow?
>>
>>2031289
No, but they offer the same ratio as everyone else now, it used to be that Sturmeys were 25% reduction/increase and Sachs and Shimano about 33%. Correct if I'm wrong, but at the moment, there's no 3 speed on the market that would have ratios other than ~33%?

There are still plenty of that era Sturmeys around in the 2nd hand market so I don't think the advice was that unreasonable, keeping in mind the general caveat that with the last old Sturmeys the quality was hit and miss. Can we count on the survivor's bias at this point?

With 25% it would be feasible to treat the 2nd gear as the default by gearing slightly up. 3rd would still be usable for good conditions and 1st becomes the 'coasting' gear for bad terrain. For hills, there's pushing.

With 33% and upgearing the 3rd becomes too heavy for almost every condition. Instead one tends to treat the 3rd as the universal gear and adjust the overall ratio down if anything. 2nd is the 'coasting' gear and 1st is reserved for hills and snow.

Curret market options force a certain driving style upon us, is all I'm saying.

A 5 speed would be the solution, an overall range a bit more as with Sachs/Shimano, but extra gears also where Sturmey has them. Unfortunately:

Is it possible to make the gears inside IGH modular, choosing the right step for yourself?
2-3 speed IGH with a range of 400-500% would be IDEAL!

cheaper to pay for deisel than to maintain power lines over all the distance trains cover. you could probably electrify a couple of lines and have locomotives with both capabilities but then you run into problems with large freight loads (the part that makes enough money to maintain the infrastructure) on leased tracks and put amtrak even deeper in the red on ones they own

Road signs. What do you think of them? Which country does them the best? Would you change anything in the Vienna Convention on Road Signs and Signals?

>Stop and give way are distinct shapes to make sure you can tell what they are even if snowed/iced over.

Also, you typically have to look for the backs of these signs to know if you have priority in the intersection or not. (Though usually the general road layout makes it clear enough.) Because they are very stingy with these >>2031484 around here.

Like the priority sign is reserved for high speed country roads and never seen in urban environment. The sign tells you that all the intersecting 'carriageways' are to yield. This, even if most of them don't have the fucking yield sign, just a name sign, which is supplied by the road maintainer, that is the sole owner of the road, or like a cooperative with 3 members in it. That you are supposed to yield coming from there because there is a priority road is just 'everyone knows' territory. Besides, the cars are going 100 at the main road and you ar approaching at 30, what are you supposed to do even if you are coming from the right? Many of such places where there is no priority sign yet this is what you do.
>>
Just learned that burgers use stop at literally 90% of intersections. Seems really pointless. You don't need to actually full stop at roads with good visibilty and with no one coming.
In Europe almost all of them would be just yield signs.

>The worst is the 4-way stop.
Why?
>Most of those places would be fine with a hierarchical road structure,
What's that mean?
>or a roundabout
They take up a lot more room than a 4-way stop, driving up the cost. Also terrible for 18 wheelers to get through unless the radius is sufficiently large, which again drives up the cost.
>>
>>2033175
>>2033177
4-way stop seems to be the same as an equal intersection in europe. although I assume it's distributed differently
