Emerald City.

while not the same as high speed rail and usually not as fast as a metro, some trams systems can be quite high speed in certain sections depending on the train technology used. tram trains, like those often used in German stadtbahns or some North American light rail can go at pretty good speeds for being a tram vehicle. "High speed tram" is probably referring to it being high speed relative to an ordinary tram, as this line is an orbital light rail which runs through helsinkis putter suburbs, connecting outer suburbs and multiple transit lines, hence being higher speed than a prototypical urban tram.

All left-green governments love slums and poverty. You are only seeing the best part of it here, you should take a look at the hideous slums being built in the new urban areas of Helsinki. Search for Postipuisto, Kalasatama or Ruoholahti. When and if people accrue wealth, they will invariably move away from the slums and the Green "15-minute cities".

Most trams in Helsinki average lower than 30km/h. This isn't that much faster though.. Maybe over 30km/h.

From the data that I found, they have been increasing the frequency over time. From the initial headways of 12 minutes in 2023, to 8 min now, and apparently 6 min during peak hours. To provide the same capacity with busses, you would need frequencies of 4-3 min, which considering the labour costs in Finland would be rather expensive, and there would obviously be 2x the vehicles to store and maintain. So using trams seems pretty justified to me. Don't know why they use the 70 km/h as a marketing point, when regular busses can go at such speeds as well, but that's a question for the marketing department, not the planners.

@Ruzzky_Bly4t buses can be articulated with 200 pax capacity, especially if they made like trams, with most capacity standing not seating. These buses can run twice faster (not only max speed which is 1.5 = 100kmh, but all loading, congestion on interchanges and so on) so require the same number of vehicles. And, of course, they are much more convenient as bus can drive on majority of local roads after it leaves dedicated trunk path.

you can continue driving bro, the tram won't hurt u bro :DDD

@kos-mos98 nope. We have tram here, pet project of Sydney major. It permanently destroyed one of main roads ANZAC pde as now it has only 2 lanes, it goes - on dedicated path! - slower than buses and it costed $3B. As bonus they regularly crash to cars, including fire truck righ in the middle of city, you can find clip here on yt. All this of course does not hurt anybody.

@@antontsau tldr?

Not catchy enough, even if it's more straightforward

there is no english counterpart for "pikaraitiovaunu" so naturally it will be translated to the closest word in english. these words really don't matter that much 😑

Yes. A way for a High-Speed train is other than this.

Trams don't need to be sped up, they just need to be used for what they're designed for: denser urban environments. For longer stretches between stops, use the good old suburban busses and trains. In my city, the trams go through the center faster than cars or busses, because they have a separate right of way with priority on intersections. Beyond the city limits, where top speeds aren't limited to 50 km/h, the busses go significantly faster, and suburban trains reach 120 km/h. I suppose the reason why low-floor trams aren't that fast is limited by some technical aspect or another, and can't just magically be fixed.

for rail transport be faster than car (in rural, so 90-100 kmh) requires full scale line control, not only line of sight driving. Signals, automatic speed control, blocking, emergency braking and many many other things, allowing speed at least 120kmh on railways. Huge money, available only for full scale trains with 1000 paxes each, every 2 min next train. Other way it will be massacre.

@antontsau Maybe, but then why do they call it "high speed"? Also what's the point then if it is slower than the bus it was supposed to replace?

@@AntonFetzer because they VERY want to do this. Ahhhhh our new tram! Fast! Convenient! And bike path! Ahhhhh! Not as these naaaaaaaasty ICE buses and Hellish Cars! Usual greenish nonsense.

@@antontsau line 550 was overcrowded and got stuck in traffic. You would often see multiple 550 busses bunched up in a line because traffic is inconsistent. the point of the "lightrail" was to have higher capacity and at least mostly avoid going on the same roads as cars. i'll admit the high speed part was probably mostly marketing tho. stop this bullshit about "greenish nonsense"

@kos-mos98 so instead of improve bus service they spent huge money for rails and trams with cries "trams do not stuck in traffic!" - oh yes, as they got dedicated path. Awesome. Greenish nonsense as usual.

It's totally as well as absolutely a high-speed tram dear Mr. expert.

@@Scandinavian92 it's very high-speed, indeed. In fact it is as high-speed as the 560 bus it replaced. Lightning fast.

​@@Scandinavian92 It's slower than the car traffic next to it on several sections. Feels absolutely frustrating to watch the overtaking cars when sitting in the line 15

@@Scandinavian92 for tram only. Buses on dedicated road easy roll 90-100 kmh, if you so like public transport. Cars 130.

@@AntonFetzer "It's slower than the car traffic next to it on several sections" Yes, it seems to be a light rail/tram line. Why do you expect a tram to go faster than cars? The only thing that is faster than a car, is a train.

And?

@@mikaveekoo And what?

@@EdwardM-t8p Americasplaining.

T2 and T3 have a different type of tram with fixed bogies on modules 1,3,5 (or 1.3.5, 7 on T3). These are prone to yawing. This Helsinki tram has swivelling bogies on bogies 1,2,4,5, which would make them more prone to yawing, but not as bad as a fixed bogie tram with suspended sections. I think the Škoda tram for Bratislava (and the new tram for Prague) with swivelling bogies on the ends and fixed bogies on modules 2 and 4 would not have a yaw issue. The new Citadis for Paris T1 has a similar arrangement, but on different modules. It would be interesting to hear how that rides.

you can feel it but its not too bad

It's known as hunting oscillation and results from lowered stability due to the tram's conical wheel profiles. You need to have conical profiles on fixed axle wheelsets in order to not derail in curves. If you can build your tracks with shallower curves, you don't need as steeply angled profiles and can drive faster without hunting, but that's not usually possible when you want to fit the tracks along pre-existing streets. You can also drive slower to reduce the hunting, but that's counterproductive to moving people around the city. Of course, getting trams with differential wheelsets would work as well. You'd just need to pay way more.

This is one of the reasons for "tram-trains". Sure you can reach top speeds on normal light rail vehicles, but comfort inside on long stretched of top speed of 70 km/h is not always guaranteed. Tram-trains use different suspension allowing them to go higher speeds (up to 120km/h) more comfortably.

@Nelchihaak This tram type has five sections. The four outer ones have one bogie each. The middle one has no bogie. Even if the bogies would not hunt at all, the sections carried by each bogie are free to swivel a bit around the vertical axis. Surely that also has some effect? If at least one section would have two bogies (as in the older Artics, and the Tampere ones), that section would be ”locked” relative to its bogies which would improve the stability of the other sections, too. At least that is my guess…

My girlfriend says she feels nauseous in the line 15 because of this wobbling. It's definitely affecting passengers.

The tramway is in Vallilanlaakso park located between Mäkelänkatu and Hämeentie: 60.20090, 24.95366 ☺
