In the 1990s I worked in a wagon manufacturing factory. At that time, these ore wagons were manufactured for another railway company. The wagons had a rotating hydraulic pump on one wheel set. When the pressure accumulator was full, the pump runs freely. On the side there was a lever between the automatic and DB, which deactivated the automatic in the DB position. Then there was a second lever: open, closed, automatic. This meant that the doors of the wagon could be opened and closed manually. The levers were mechanically secured against accidental adjustment. In addition, the wagons had two big solenoid valves. If both solenoid valves received a strong magnetic field, the doors opened automatically. After a set time, the doors closed again. The control was completely hydraulic and required no electricity.
Well, we call them: "Schwerkraft Selbstentladewagen" [Gravity Selfunloading waggons] EDIT: Regarding to the topic, their Grain carrying version "Hopper Kkt" was also a Game changer for agricultural bulk cargo.
Here in Denmark we only employed them for a few decades for the power plant "Herining is Vestkraft" Pooling coal trains from Esbjerg harbor to the plant in Herning from 1981 to 2000 when the plant switched from burning coal to I believe it was biomass. The Saddle wagons were locally build by Skandia in Randers under license from Talbot, there were 18 of them, all painted blue with "Herning Vestkraft" written in white letters on the side. They were either pooled by a DSB My in one end and pushed by a DSB My at the other end, or pooled by a single DSB Mz.
The trouble with the term Selbstentladewagen is, that it's a very general term including also many other types of self-discharging wagons, while Sattelwagen on the other hand is specific to this one family.
You can see blocktrains with these family of hopper cars on a daily basis on the major freight routes from Amsterdam/Rotterdam ports into mostly Germany transporting Coal and iron ore. The brown ones are mostly used for coal and iron ore and other colored cars for other bulk cargo. f.e. the light grey version of these with tarps over the top are used for transporting chalk from Belgium and France to the blast furnaces / cement making industries in the Netherlands and Germany.
Interesting video. The famous Consett Steel Works - Tyne Dock line in UK used a similar design for bulk automatic unloading of Iron Ore. The Consett Ore Wagons were based on an LMS design that in turn was based on the German design.
Superb work again sir .... as an aside, similar wagons were used on the metre gauge system in Morwell Vic Australia of the State Electricity Commission SEC with electric locomotives built by Henschell until the system closed in 2007
Saddlewagons were introduced to Brazil in the mid 1970s when FEPASA ordered the first of 3 series from MAFERSA based on the german design. They were classified as GHD with G for Gondola, H for Hopper and D standing for 80 ton gross weight on 1000mm gauge. They carried a multitude of bulk cargos like sulfur, grain, coal, phosphatic rock and slag. They were rather common until the early-2010s when their number began to dwindle. You can find quite a few of them abandoned today.
I have a Piko DDR era Deutsch Reischbahn Zugpackung that has 3 of these hoppers, A V106 0-8-0 Diesel locomotive (not to be confused wiht the DB clas 106/260 0-6-0 diesel and unloading platform.
And I thought the ET165/166/167 Series S-bahn Units for Berlin where one of the Oldest Trains in Germany... I mean, few Modes where in service for almost 70 to 80 Years.
I mean, these wagons haven't been kept in service for almost 100 years, it's just the basic design which is that old. The wagons currently running were built much more recently, from the 80s I believe.
So why the hell they put Scharfenberg couplers on them? How was connection to locomotive handled? screw-scharfenberg connector has rather low durability and is susceptable to pushing. There is no buffer wagon on your renders.
All Scharfenberg couplers on these wagons were fitted with conventional links underneath them (not present on my model) and could therefore directly couple to a locomotive's hook without needing an adaptor.
As explained in the video itself, the welding technology improved enough for it to be used for the wagons. It eliminated the heavy riveting system saving enough weight for a set of bogies to be slotted in without maxing axle loads. With even better and more heavier railroads, the surprisingly heavy built wagons can carry even more load than before without much design change as high as the axle loading permits on the railroad.
A small number of wagons intended for transporting sand had an even steeper angel (55 degrees rather than 50), therefore I suspect the steep angel was indeed necessary to ensure a complete discharge.
@@steelbridgemodels It accounted the angle for any wet loads that are stubborn enough to cling on and hold together. With a lower angle, you would now need an agitator or vibrator/shaker to dislodge the stubborn load. A common issue on the US gondola with a wet coal load (it is needed to be wet to minimize risk of dust creation and prevents dust explosions). The railroads there permits far heavier axle loads and maximizing load is a must as the load requires to travel longer distances. With more load means more profit per trip. To unload the gondolas, they use a vibrator/shaker that is lowered on the unloading bay and clings to the gondola body and shakes the heck out of the gondola. Its a time consuming process as it is used individually compared to the now European standard where you can unload it on the move too without having any issues.
Knuckles sind auch nur bedingt besser, die haben meistens so viel Spielraum, da kriegste keine automatisch gekuppelte Luft mit. Ich glaub der Kanal „Der Silberling“ hat n paar Geschichten zur „UIC 69“ Kupplung (Europa Äquivalent zu den US Knuckles)

I can’t believe these bulk wagons from the 1920s look so contemporary!
Theres only so many ways to maximise a bulk load wagon with sliding doors within a certain loading gauge \_(._.)_/
Yeah, it's really just the rivets that give away the age of the original design.
The same principle is used in iron ore wagons with separable bulk containers (RockTainer Ore).
In the 1990s I worked in a wagon manufacturing factory. At that time, these ore wagons were manufactured for another railway company. The wagons had a rotating hydraulic pump on one wheel set.
When the pressure accumulator was full, the pump runs freely.

I thank the youtube algorithms for suggesting this to me. I didnt know i needed to learn about this, but I did!
I love your 3D models! Beautiful!
Thank you so much!
Fantastic video! I am modeling 1950-1953 German rail and now I know what Erz wagens I need to buy.
Thank you! I'm glad my video was helpful! The early 1950s are fascinating years for modelling with so many possibilities.
@@steelbridgemodels Also very forgiving because you can get a ton of rolling stock second hand for very cheap
The UK (LMS and BR) had a rake of these also.
Ouh klasse. Einer der schönsten Güterwagen überhaupt. Danke für das Video😊✌

There were some similar wagons used on ore trains at Consett in North East England

Ive never seen people calling these Saddlewagens, I'm more fimiliar with the term Selbstentladewagen

Super cool love to see more content
I think a Video About the Br151 and the Faals 150/151 with AK69 Coupling is needed now :D
Thanks especially for the Sharfenberg couplings gonna put some on my H0 waggons.
Is there literature as to why the early DB discontinued the Auto-couplers? Or conversly, why their production was continued through the war?
Perhaps a Video about Eanos?
Superb work again sir .... as an aside, similar wagons were used on the metre gauge system in Morwell Vic Australia of the State Electricity Commission SEC with electric locomotives built by Henschell until the system closed in 2007
Perhaps you could make a video about Pwg (Güterzugbegleitwagen), the equivalent to american caboose. One is already seen in this video.

A video about heavy weight wagons like marklin 4617 would be interesting.
The ever common FALNS and Fals hoppers
i love your channel

i would love to see a video about the DRG BR05 001 streamlined (the steam train that was the fastest steam train before mallard rode down a hill)
What is the function of the white painted square markings on the lower 1/3 of the rolling stock?
They were used to indicate what type of brake system a wagon is equipped with, in this case (two squares) a standard goods brake.
They look like still in date even tho its like 10 decades old
Would this type of wagon carry limestone also? A requirement for blast furnace made iron.
Yes, they do! There were and still are covered versions with lids or a pivoting roof over the top to protect the limestone from the weather.
I love your video's ❤
Europe really needs to shtcan screw couplers.
Ausgezeichnet!
Yo it would be a cool video about gards wagons
A video about guard wagons is coming sometime soon!
On a related topic, I would also like to see one on end-of-train markers.
And I thought the ET165/166/167 Series S-bahn Units for Berlin where one of the Oldest Trains in Germany...
I mean, few Modes where in service for almost 70 to 80 Years.

I've seen these wagon getting pulled a lot by ČD Cargo
can you do a video on German lokos 1910-1933.

All Scharfenberg couplers on these wagons were fitted with conventional links underneath them (not present on my model) and could therefore directly couple to a locomotive's hook without needing an adaptor.
did they ever solve the poor running or do they still max out at 50kmh today D:
Current day ones run at 100-120 kph, like all other modern wagons.
As explained in the video itself, the welding technology improved enough for it to be used for the wagons. It eliminated the heavy riveting system saving enough weight for a set of bogies to be slotted in without maxing axle loads. With even better and more heavier railroads, the surprisingly heavy built wagons can carry even more load than before without much design change as high as the axle loading permits on the railroad.
I'm just confused why the angle is so steep, leaving a lot of unused space in that peak.
couldn't it be much better if the slope was a spline curve?
Nope, it would lead to cargo left behind.
A small number of wagons intended for transporting sand had an even steeper angel (55 degrees rather than 50), therefore I suspect the steep angel was indeed necessary to ensure a complete discharge.
