Missed opportunity to mention Eschede train disaster from 1998 - where attempt of bringing back compound steel/rubber wheels end up in one of the deadliest train disasters in Europe.

[@GrandProtectorDark]

Nah, Enschede isn't comparable. They weren't really trying to "bring back" the design. The idea of putting a rubber ring layer between the steel wheel and the steel tyre, was a concept already in common usage around the world..... On trams. The design technically works just fine at what it's designed to do, the problem was, that it's simply not suitable for the stress of high speed trains.

[@pxlcowpxl6166]

​@@GrandProtectorDark The main problem was poor maintenance. There was a crack in one steel tyre big enough that it shouldn't have been allowed to run anymore. Only at slow speed to the next workshop. Compound tyres work fine even on high speed train when properly maintained, but they add a layer of complexity and potential failure compared to monobloc tyres.

[@Sacto1654]

@@pxlcowpxl6166 No to mention the fact that railway suspension systems have improved a lot since the 1990's and modern air suspension systems (e.g., the suspension on the N700A and N700S Shinkansen high speed train sets) have made ride quality based on the wheel design moot.

[@Dirk-Ulowetz]

​@@pxlcowpxl6166Das Problem war: Durch das Aufschrumpfen der Radreifen bei Monoblockrädern standen die Radreifen unter Spannung. Risse zeigten sich folglich Aussen. Also genügte Sichtkontrolle. Man dachte, das würde auch bei den neuen Rädern genügen. Aber durch den Gummi neigten die Ringe zum Walken. Dadurch bildeten sich die Risse auf der Innenseite der Radreifen. Der Riss, der zum Bruch des Radreifen führte, hätte nur durch Ultraschall entdeckt werden können. Das war damals aber, wie oben erklärt, so gut wie nie statt. Der Radreifen war allerdings auch schon etwas zu sehr abgenutzt, man dachte aber, das könnte man auch erst ersetzen, wenn der Zug in Hamburg wäre, wo sein Heimatbetriebswerk war. Da kam der Zug aber nicht mehr an...

[@pxlcowpxl6166]

@@Dirk-Ulowetz Danke für die Auffrischung. Ich wusste, dass der Unfall durch grobe Fahrlässigkeit möglich gemacht wurde, aber nicht mehr genau wie. Wenn ein Radreifen zu sehr abgefahren ist, dann muss das Fahrzeug unbedingt bezettelt werden und darf dann nur noch mit verringerter Geschwindigkeit und ohne Fahrgäste (bzw. Güterwagen ohne Fracht) bis zur nächsten Werkstatt fahren. Da gibts kein wenn und aber. Man muss nicht wissen, was im Radreifen alles passieren kann, wenn er zu weit abgefahren ist. Die Sicherheitsvorschriften im Eusenbahnverkehr sind nicht zum Spaß da. Übrigens, man unterscheidet zwischen Monoblockrad (ganzes Rad ist ein Stück Stahl) und, wie in dem Fall, bereiftem Rad (besteht aus Radkörper, Sprengring aus Gummi und Radreifen außen daraufreschrumpft). Früher gab es auch noch das Speichenrad.

The Montreal Metro is dependent on its rubber tired trains because the gradients it uses are too steep for steel wheels without a fourth rail with grooves to assist, but that would dramatically slow it down.

[@u2bear377]

A "rail with grooves" is called a _rack_ (as in "rack and pinion").

[@00Zy99]

Actually, improvements in traction control now allows conventional rail technology to conquer the slopes unaided. When there was a call for new rolling stock recently, at least one bidder offered conventional rail technology. It wouldn't even require a retrofit, since the Metro (as in Paris) already has steel rails of standard gauge in place, along with a third rail.

The limiting factor in acceleration of trains is not the adhesion of steel on steel but passenger comfort. It is expected that passengers can walk around in a railway carriage. Consequently acceleration is normally limited to about 1/20 g. (1 mph/second) Steel wheels can easily achieve 1/10 g. If you have ever been standing in a carriage when the driver makes an emergency brake application, you'll know exactly what I mean.

[@u2bear377]

> acceleration is normally limited to about 1/20 g. (1 mph/second) What does this come from? Commuter and subway trains seemingly accelerate faster.

[@ramdom_player201]

@@u2bear377I haven't looked it up to verify, but it seems to make sense. Long distance trains might limit their acceleration and deceleration for comfort. But commuter and subways trains travel short distances between stations, and it would make more sense to speed up and slow down at a higher rate. These style of trains tend to have overhead grab loops and poles, for people to hold onto so they don't fall over during acceleration.

[@Gelatinocyte2]

@@u2bear377 I think that's the point: commuter trains and metros in general sacrifice comfort and max speed for increased acceleration/deceleration and service frequency.

[@SimonWoodburyForget]

Wait... so the only reason trains don't accelerate faster is because passengers don't like spilling their tea? Food for thought, but couldn't you just tilt the carriers by a few degrees and completely eliminate the feeling of acceleration? Oh... and I'm not saying it would make sense to implement just for a couple seconds of acceleration... just a random fun idea.

[@Gelatinocyte2]

@@SimonWoodburyForget well, metro and commuter trains do accelerate faster, because they don't expect you there to be having a cup of tea. "Normal" trains (regional, HSR, sleep) are always slow from the start - ideally for only a couple seconds, more if it's the antiquated "prime mover" train.

[@michaelwright2986]

Perhaps worth mentioning the Paris Metro, which converted some lines to rubber tyres after WW 2. The advantages of quick acceleration and braking, and quiet running, would seem especially useful for a commuter line, and maximum speed isn't very high. Rubber dust everywhere would be a particular problem in tunnels, though.

[@bocahdongo7769]

80's EMU onward already have insane acceleration anyway to the point it already on 60 kph right after leaving the station, so the point is kinda moot anyway.

[@swayingGrass]

recurring correction: while a wheel deforming generates more grip due to larger contact area, the grip is what effects rolling resistance. It is the not-100% efficiency of the wheel deforming and un-deforming. If you think for a second, a non-slipping wheel would have 0 speed difference between it and the rail/road, making grip a non-factor.

[@ImperatorZor]

The picture of the Silver Slipper at 8:15 is actually taken on the Reading Railroad. The Budd Company was native to Philadelphia, which was also the headquarters of the Reading and the Pennsylvania, probably one of the reasons why both were so ready to buy in so early. The Reading, in particular, was the railroad primarily used by Budd for factory deliveries and initial testing of equipment. Many pictures of Budd equipment can be found on the Reading system, even if they were not intended for use on the Reading. There are rather famous pictures of the Budd Metroliner and Silverliner-both intended for the Pennsylvania Railroad and painted/signed as such-on Carpenter Siding at Jenkintown. Pictures of the Rio Grande's Prospector at West Trenton station also exist. The exceptionally straight, level, and fast, New York Division between Jenkintown and West Trenton was the preferred Budd test track, especially after the move to new, larger, facilities at Red Lion Road, which was directly alongside said route. The reason that the picture of the Silver Slipper can be identified as being on the Reading is because of the catenary support on the left-hand side of the picture, especially the angled support between the horizontal and vertical steel I-beams. That is very much a Reading electrification hallmark. Interestingly, the New Hope branch left the Bethlehem Division at Glenside station (technically CARMEL Interlocking a bit beyond it), which is the next station after Jenkintown, about two miles away. The Reading's railcar, however, would not have usually seen service at Glenside. 1931 was when the Reading inaugurated electric service, and the New Hope branch was included as far as Hatboro station (the last station in Montgomery County), with New Hope service generally being a shuttle from there through Bucks County, which rather quickly got a bit more rugged and therefore less suitable for suburbanization. Incidentally, the accent is on "New" instead of "Hope". NEW Hope. Just a local quirk.

Steel's efficiency has nothing to do with slipperiness. This is a painfully common error in education/edutainment and misleads a lot of people. You use the word "friction" to refer to both "adhesion" and "rolling resistance", apparently confusing the two which have basically nothing to do with each other. Good adhesion doesn't waste energy, it's what lets you accelerate and brake. Steel on steel actually has pretty good adhesion most of the time. High rolling resistance is what just wastes energy. It mostly comes from the periodic deformation of the wheel while rolling. Steel doesn't deform like inflated rubber.

[@Lucius_Chiaraviglio]

A clarification about friction: The friction that you need for starting and stopping is sliding friction of surfaces. More of this does not necessarily impede motion at continuous speed -- after all, consider cog railways. Rubber tires have an additional way of losing energy, though -- they flex much more than steel wheels, and that flexion is not perfectly elastic, but instead dissipates some of the energy that went into flexing them as heat. This type of loss will occur even if the wheel is operating on wet or icy rail, which greatly reduces the sliding friction but leaves the flexional friction unchanged (apart from whatever effect temperature has on it). That said, many HiRail vehicles use rubber tires on the tracks. (A fair subset of HiRail vehicles have the rubber tires lifted off the tracks entirely, and if they use them at all it is by pressing them against the steel wheels that run on the rails -- this is not about them.) The HiRail vehicles that use rubber tires directly on the tracks also have steel guide wheels. Of course, HiRail vehicles have rubber tires for the purpose of road travel (in some cases even off-road travel) when they are not on the rails, so the drawbacks of rubber tires are viewed as acceptable. They are usually maintenance of way vehicles, and in some cases road-capable yard switchers, thus lessening the impact of the drawbacks of rubber tires. Even so, I have seen videos of a Hi-Rail truck acting as a locomotive, pulling a substantial train on a standard heavy rail line. For example: kzbin.info/www/bejne/r4Kzi4OVnsusn9k and kzbin.info/www/bejne/jV66Xp1-pbKVrpo Of course, the rubber tires available today are a LOT tougher than those available in the 1930s.

something similar i could already see coming with these was if tires went mainstream for railways, especially if they were put on rolling stock, would be the friction between tires and rails. it might work if it was the railcar situation where every wheel is powered, but if you put it on rolling stock or even just engines with bogie wheels, there's the possibility the tires might just not turn since it's a smooth, slippery material on smooth, slippery material.

I would assume the rubber tyres decrease the amount of wear on the track. Underground systems must run constantly so minimising track maintenance is a must, have good acceleration and breaking as well as tackling steep slopes. Underground trains are never too far from maintenance facilities. Moving the maintenance burden from the track to the rolling stock could find some niche uses with underground systems but tyres do generate the most heat under acceleration and breaking. The tyre dust problem still may not be fixed though.
