About paper wheels and rubber tyres: In my view, travelling comfort has notably been raised by the implementation of "long-welded" rails. (Please replace my literal translation from Dutch with the proper English term(s).) After all, removing the bumps is better than finding cures for handling them.) Besides, a great part of railway safety, signalling and electric traction (globally, to my knowledge) relies on electric circuits using the rails and wheels as conductors. So, it makes sense to locate suspension devices not at the wheel level, but rather at the bogie level. (This obviously requires only bogies to be applied, which would be impossible for "all" steam locomotives.)
It wasn’t so much the paper degrading, though that did happen, it was the constant flexing of the steel tire. This flexing caused fatigue failure that ended up allowing the wheel to lose tread sections. A good example of this is the train wreck in Germany of an ICE high speed train.
The PCC streetcars,used a rubber insert on their wheels,cut the noise,and there was also a rubberized suspension system on the trucks! So,paper wheels,20th century style!

The french PLM company 220 (440) "coupe vent" (wind cutters) were succesful. The streamlining purpose was to reduce the effect of strong wind that blows from Lyon to the south east coast, the "Cote d'Azur", through the Rhone river valley, called Mistral. The characteristic shape of the cab eventually survived up to the last steam locomotives built in France, 141P (282) and 241P (482). Because it looked cool though...
Bert Meinders The first "Windsplitter picture shows Walschaert valve gear with piston valves. It's generally believed that the NZR B class 4-8-0 of 1899 was the first to combine the two features.
Yes, but the wheels don't run on the rail, but on seperate larger concrete bands. There were 4 major issues with the Micheline railcars and trains : - the wheels had to be narrow, because of the width of the rail, limitting the weight they could handle. The railcar needed to be very light and the number of wheels multiplied - because they were light, trains wear out very quickly - there were often punctures, due to laminating rails mainly (locomotive slippage leaving steel chips attached to the rail). A wheel or two had to be changed during most of the journeys, and replacement was not easy task, the wheel weighting almost 100kg (200lbs) - there was considerable resistance and a lot of power was required from the locomotives. And the crew could not relax : they needed to pull continuously, contrary to a steel wheel train where they just had to let it go in descents. Paris (and Montreal) metros don't have these issues.
The tracks are not classic railway tracks they are flat steel or concrete. The advantage of that metro system (more adhesive tracktion/breaking) outweighs the negativs. Also the GLT trams (guided light trams) use pneumatic tires and are guided with 1 railway track in the middle. Its an enginering solution that can benefit in special occasions like very thight curves and fast / often exeleration /breaking.
Montreal metro: laughs in fully underground rubber tired system. I kid you not our oldest trains are turning 50 in a few years and They are legendary in montreal.
It may be worth noting that 100 wheels wouldn't go a long way on Pullman cars, as they typically had 3-axle bogies. That would be enough for up to 8 cars and a few spares. I'd be interested to know how many cars were ultimately fitted with these wheels, and how many rainstorms they would typically survive!
Pneumatic tires on rails is still quite common...hi-rail vehicles 😅 Had pneumatic tires for rail vehicles caught on, then another drawback would have become apparent: the coefficient of friction of steel on steel is one of the lowest known coefficient of friction (this side of leather soled shoes on ice). Increasing this friction takes away one of the railroad's intrinsic values: the low coefficient of friction makes rail travel fundamentally more efficient (from an energy standpoint), which goes away when you introduce more friction.
I have a suggestion: 5 planes that ended up where you’d least expect. Also a suggestion for that: the S199 aka the Sakeen. It was a version of the bf109…that was used by Israel.
Not only planes also the Panzer IV ended up at the IDF. Captured ones (Syrians in 1947) were later even destroyed by the IDF with Shermans and Centurions!
And some lines at Mexico and Santiago de Chile too (but ALL OF THEM have also metal wheels behind the rubber ones). And the VAL metro and other small automatic metros all around the world have tyres instead of rails (and some weird turnouts to be able to use them without rails).
Paper wheels did get 50 years of usage in them as a technology and, frankly, as they pretty much ceased to function at speeds above 50mph. Then again, having composite wheels on trains tends to fail in spectacular ways. As germans can attest.
Mi local railway museum has a French manufactured railcar for a colony that has rubber tires. Was able to ride on it back on the day and the ride was not only smooth, but super quiet as well. Even back then I could grasp the issues regarding these kinds of wheels, but damm it was impressive.
Speaking of failed tires; the Eschede train once had tries with an additional layer of metal. However, that layer of metal led to one of the most disastrous train accidents in history.
Quite! It has led to the phasing out of metal "tyres" around the wheels of trains (in Europe, at least in Germany), and in the meantime adding white marker lines on wheels with these tyres, so that relocated tyres can easily be spotted. (Note: there is this Eschede in Germany, and there is Enschede in the Netherlands, on the border with Germany.)
Only Benefit I could see for "wind-Splitting" is fuel economy and when the locomotive has to travel against gale force winds. Stream lining is different cause it also does wind-splitting but it adds extra weight which adds tractive effort to the locomotive. I.e. the streamline locomotives could pull more stuff with no extra added motive power.
@@chrislaarman7532 Thanks, Chris, for confirming. I should also say that, contrary to what I implied, I know definitely that I travelled on the metro in Paris, but was unsure about the rubber wheels.
@@nicolek4076 "Together we can!" ;-) Anyway, see en.wikipedia.org/wiki/Rubber-tyred_metro or preferably fr.wikipedia.org/wiki/M%C3%A9tro_sur_pneumatiques.
@@chrislaarman7532 no. The system has conventional rails and wheels behind the tyres to use turnouts and solve the issue of a blown tire. Also, the system is used at Mexico, Montreal and Santiago de Chile. There are also automatic metros with tyres and no rails, but that is a different kind of system.
Aerodynamics is still a waste of time when it comes to trains. Applying aerodynamics to trains is like applying it to a brick, It may look fast but it's still a brick. The Aerodynamic Siemens chargers that Brightline uses literally have the same fuel consumption as the normal chargers, they also can go the same speed in the same amount of time. It's like putting lipstick on a pig, no reason other than looks and it looks awful.
Been binge watching your videos.... You need to make a Top 5 streamlined locomotives, possibly one part for 4-8-4's and one part for 4-6-4's, maybe one for Worst 5 as well, for ugly, failed, streamline locomotives.... There's enough out there for US v Europe v Canada....now, get to it! 😉😆😂 Oh, btw....Milwaukee Road RULES! ✊🏻😎 Keep 'em videos coming! 🤜🏻🤛🏻🍻
Well, that, and paper has two other qualities that make it unsuitable for making train wheels; 1) it gets soggy (and warps) if you get it wet, and 2) it’s FLAMMABLE! Combine the heat from braking, with flammable paper train wheels, and oxygen from the air, and you end up with train wheels on fire! And burnt paper has NO structural rigidity. And the fire would burn up the axle grease in the journal bearings. Super not good. It’s a good thing they were banned.
EMD was driven to distraction by railroads' own locomotive rebuilding programs. Santa Fe CF7s, ICG's Paducah rebuilds, Seaboard's GP16s. Hence the BL20-2 and the GP15.
Research the Montreal subway system. They use rubber tires and flanged wheels. VERY quiet and where they have to switch tracks the rail wheels come into play. Paper wheels did fail BUT they didn't fail as badly as described. They were constructed in such a manner that the outer disks that compressed the paper could also support the wheel if the paper wore out. My railroad had a snowplow we used up intot he 1980's that had a couple wheelsets that had paper wheels.
11:40 wait wait wait, lets not skip over that paper from straw, why are we not still doing that? it sounds like the perfect middle ground... we already harvest a massive amount of grain globally and not all of the straw goes to animals, so why not use it to make paper? less crop waste and less logging... seems like a perfect idea.
Use the tank wheels for trains. Steel - rubber sandwich - steel outer. Best of both worlds and they last. I think the Panther used them along with the Interleaved German tanks and some 30s European stuff used them. You also had Roadable tanks with removable tracks and steering front axles..
Those rubber insert also used in ICE old wheel. It indeed made the ride insanely smoother, quieter, kill hundred of people, and still quite stable on super high speed

Samstrains will be Amused and triggered and laughing
The transit systems in airports use tires too even though it's on rails. Probably for easier maintenance and smooth ride.
