Guide Riesa-dresden: Tips On Driving Freight Trains Realistically.

To be fair, I didn't expect the 187 to have the GPR-selector. It was introduced way too close to the 187's release for Skyhook to implement it. Still, as you say, OpenMinded, it would have been a nice addition and given you 2 options for proper freight trains on DRA.

 

I give you that. It is a most unfortunate timing then.

 

That is something, I can answer also add something additional here. If you drive an old locomotive like the Br 111 or 110 btw counts for the GDR Locomotives as well in R. It enables via mechanical parts and valves an additional brake pressure for the brake cyclinder to counteract the low performance of the iron block brakes by high speeds. It switches by 110 and 111 from "Niedriger Abbremsung" to "Hoher Abbremsung" by 70 km/h, which increase the brake cylinder pressure to 8.0 bar in case of failure of the dynamic brake. It goes back from "Hoher Abbremsung" to "Niedriger Abbremsung" by 55 km/h which is by Niedriger Abbremsung to 3.8 bar.

As long, the dynamic brake operates you will not see the 8.0 bar.. Except, the locomotive doesn't like you. A pretty similar function is working in the Br 143. If you have one of those dinosaurs, you have to set the Brake Mode to P if you run the locomotive cold(Switched Off) because even then in R, the hohe Abbremsung would work. Also, if you don't have a working Electric you set it to P.

The reason is simple, if you brake a couple of times with hohe Abbremsung, the thermal stress on the wheels is really high. Most of the old locomotives use tire wheels, and if they get hot the tire on the wheel could start move which increases then the chance to get derailed then.

Ye, some coaches had already R but that dependendet how fast it goes etc. We had many regional coaches and locomotives which used P for a long time before they got upgraded. Some coaches, kept the P/G setting which is also because of the tire wheels. Tire wheels were back then much in use, now we use monoblock wheels.

NBÜ/ep, is fun to drive. Normally, if you apply the brake without ep, it takes quite some time to apply the brakes by every coach. You have kind of to be careful a bit and not overshoot. But if you apply the brakes with ep, a signal will be send (only possible with compatible systems) and the brakes will apply simultaneously in every coach. You have in this case to be careful, because you will most likey try to stop
perfectly but will release the brake too early. Then have to reapply it again, it is almost like driving an MU then..which also uses ep..with the difference to able the control all the brakes on the own.

Edit: The sheet on page 1, I saw it back then by SBB Cargo around 2014...we had almost the same back then.

 

Nice info! Btw, (and maybe you meant this), but the BR143 in DRA has Hohe/Niedrige Abbremsung implemented in R-brake

 

Can someone explain me how to read this table? An example will be appreciated.

 

The table basically tells you how fast you can drive a certain gradient. First column gives you the gradient, second column lets you pick the brake mode you are driving your train in, the line on top gives you the max speed to the associated BrH in the lines below.

Hope this helps and was what you were looking for?

EDIT: sorry, forgot the example:
You drive a cargo train with 86 BrH on a route with a max gradient of 1:200 in brake mode P. You pick the right line with the gradient and brake mode and follow it until you hit the next value below 86. In this case you end up with a max speed of 110. Of course, your rolling stock has to be capable of this as well...

 

Great, thank you! Now, I have another question .
Does the maximum speed restriction apply while driving on that gradient or does it apply to the entire route?

 

Strictly speaking it would only apply on this section of the track. However, in real life there are limits to how often a speed limit may be changed, in order to keep work level to acceptable limits. Hence, you would follow it for quite some time…

 

Just a quick question cwf.green, do we only have this one 2700T train or are there several? If yes, which service is it?

 

Like Matt mentioned in the stream I was going to make a thread/document that detailed each service and what train formation is used. Unfortunately real life got in the way and I’ve been completely swamped with work the last week but I’m hoping to make the thread some time next week.

I can say that the 2700t train is used in 4 services though:

09:36
13:46
18:08
20:42

All services are northbound via the avoiding line.

 

Anyone knows the brake weight of the Uacns wagons?

 

Is it not written on the changeover device?

 

I'll check when I get home if I have it written down but based on some pictures I found it seems to have a KE-GP-A brake (automatic load sensing) with either max 58t or max 60t.

But the Uacns has not had the new features implemented and I have not had anything to do with the brake force values on that wagon so I have no idea if it actually brakes according to the real BrH/bremsgewichte (most likely it doesn't based on track record).

 

Okay, if they have automatic load sensing then there should be a marking (about halfway along the side) that looks like this, with the number in the green box specifying the maximum brake weight (in the example: 58.1 tons):
But since I can't see it in the pictures you posted, it might be missing on the model.

 

There isn't anything like that.

 

Textures are only sometimes realistic. Other times they are composites of similar types of wagons or the artist have used fictional/inferred values. You can see this on many wagons in TSW if you know what the real world values should be.

In any case, if the brake is of type KE-GP-A it has automatic load proportional brake (“A”). I found the value MAX 60t but this might vary if there are multiple variants.

In the case of KE-GP-A max 60t the (“raw”) BrH will stay 100 up to 60t and the it is 60t / gross weight. GP implies it has G-brake as well as P-brake. “KE” = manufactured by Knorr “mit Einheitswirkung” (with standard behaviour/design).

 

Sorry, just want to make sure I am not confusing things

Is tygerways' spreadsheet to calculate Vmax applied to the whole route, or just the steepest section? (the 160 km/h downwards part on the avoiding line I think).

 

IRL the driver would get a local restriction, which looks like in the post I have posted somewhere up, where the speed is restricted for passenger trains going up to 160kmh, however, with a certain brh are only allowed 150kmh where it goes down hill, which you are referring to.

sorry for the long and confusing sentence, it’s late over here…

EDIT: was meant to add something. There are rules to how often the speed limit may be changed like that, as it is distracting and sometimes confusing to the driver. There is a name to that rule as well, but I don’t have the details to that, yet.

 

You can specify a max gradient in the sheet and it will show you if an additional limit will result from the gradient:

For example, a max gradient of 0,6 % results for the LL-train in DRA in a V max of 110 km/h:



If you select a max gradient of 1,1 %, the sheet gives you a V max of 105 km/h:



I personally think that a max gradient of 0,6 % for the whole route (in Dresden) is enough. If you want to take the 1,1 % that the game gives you for a gradient on the avoiding route as relevant, than you can apply the reduced speed only for the track section in question (the northern part of the avoiding line).

 

Ok everything is much clearer now. Thank you, to be honest I should have taken an in-depth look at it before.

So, theoretically the speed limit should change for every different descending gradient, but as OpenMinded said obviously this doesn't happen in reality.

So in reality what happens? I'm guessing the second option (using 0.6% gradient Vmax for the whole route and the 1.1% Vmax on the relative downhill part of the track) would be the most realistic, right? Also I wonder if they simply do not consider the gradient Vmax for longer uphill sections? That would make a big difference on other routes like MSB and RRO.

 

I can't tell you from own experience, but as much as I understand it, those calculations end up in a Fahrplan (OpenMinded posted an example earlier in this thread) that specifies the applicable speed limits for every track section on the route.

For game purposes I should say this makes enough sense. IRL I think the relevant gradients would be actually even lower (as I tried to show in one of my posts before).

 

If anyone can get DTG to give us the track profile data (and the locations of the main signals) we could actually calculate the relevant gradients for the whole route quite easily, like Lamplight suggested, and draft our own Fahrpläne..

 

Couldn't we work it out from TSW itself?

Also I was thinking about doing a simplification, diving the route from Dresden to Riesa in 4 pieces

1. Near Dresden (small ups and downs)
2. Uphill section of the avoiding line
3. Downhill section on the avoiding line
4. Uphill just before rises

It won't be perfect but maybe better than nothing?

 

If you keep track of the gradient that the in-game HUD gives you let's say every 100 meters travelled, you should be able to recreate the track profile well enough, I think. But this seems to be a lot of bother..

Oh yeah, go ahead, looking forward to it!

 

Well, only using gradient data, and your spreedsheet, the speed limit for the a loaded Zacns consist (Bremsart G), going from Riesa to Dresden on the Avoiding line would be 90km/h everywhere apart from a descending grade (1.0%) on the avoiding line (between Km1.8 and 2.6) and at the end near Dresden Neustadt (Km115.0 to Km115.4 - 1.3%), where the speed would be reduced to 85km/h. Does this sound realistic?

If this method is more or less correct I could use it for other consists as well, and create some sort of fahrplan

However does the bigger distance between main signals on the avoiding line make any difference? The braking curve enforced by PZB is always the same.

 

where did you get that spreadsheet? looks handy,is it the one from the discors invite? cause that's expired

 

It's a spreadsheet he made himself, available here
https://discord.gg/Kpv7HNve

 

you're the best,thanks!

 

Sounds good for me!

It should not, cause the maximum braking distance is limited to 1,000 meters by federal law (if not running under LZB).

 

That's great, because, I believe Ebula is "personalised" for every train (so it knows the trains max speed, brh, etc...) so it should be possible to create a sort of virtual Ebula based off already existing sources such as this one
https://rail-sim.de/forum/filebase/entry/7448-buchfahrplan-dresden-riesa/

 

Thank you so much for this! I've been trying to find a real Buchfahrplan with no success and this looks like a fantastic substitute

 

No problem, on Rail-sim.de "timetables" section there are plenty of other similar documents for TS and TSW routes, definitely recommend to check it out

 

You're absolutely right. I wasn't really familiar with the site as I'm on console, but there seems to be a wealth of useful resources available.

 

Would it be interesting something similar to this made for every different consist? if I can find out more details about how it's created IRL? for example I've only laid out the 90km/h, but I don't know if I should have drawn the speed limits as, for example:
90
(160)
or the other way around.
Still, it's just an idea at this point.

Mine is based on the document I linked above made by RailSim.de user andigladdi. And if I decided to go further I will try and reach out to him.

HERE the Google Sheets version and HERE the version with the all the speed limits in place

 

And I updated my sheet. It now contains more vehicles (escpecially the BR143 and the BR182). Moreover, I implemented the new intel that we found in this thread concerning the selection of the appropriate brake table (now follows the Fahrplan setting) and multiple car units in a long loco (LL) train.
Updated versions are available for download on my discord server.
Again, the link will be valid for one week.
Corrections and other feedback is very welcome!

These are lovely! I look forward to using them
If you don't mind, might I ask you a few questions about the abbreviations used (since I don't have a Rail-Sim.de account to ask andigladdi)?

• at km 71.4/71.6, what does El stand for? I assume it has something to do with the Schutzstrecke that is present in the TS version, but absent in the TSW version?
• at km 74.8 What does the (Hp) after Nünchritz mean?

Thanks, I figured it was about Haltepunkt vs Bahnhof but had never looked into the distinction between the two. I appreciate your work and hope your talks go well

 

In case you might be interested where the legal definitions for Bahnhof, Haltepunkt, Haltestelle etc. are set out:

Eisenbahn-Bau- und Betriebsordnung (EBO)

Good evening to all this subject is fascinating and I play more and more with freight trains just to have to calculate the BrH and see what percentage to apply and also know my maximum speed for the considered convoy on the chosen route.
But I just have a question: how in the game is it possible to set the loco to G braking mode as well as the first five wagons and leave the rest of the wagons on P mode; in other words is it possible to set the braking mode on the wagons; on the locos you just have to turn a switch but for the wagons I don't know if it's feasible

 

cwf.green showed what the switches look like on the cars here:

As the cars are set up correctly for P/P, G/P, and G/G, you'll only have to mess with the cars if you need to run LL. In this case, search the cars for a (usually) yellow lever called brake selector by TSW and switch it from P to G for the first five cars.

 

Thank you very much as I didn't even know that these switches existed on the wagons due to the lack of description manuals on the wagons. Very good to know.

 

I made my own kind of ebula (for each german route). I made it specially for the gradients, so I didn't take notes on speed limits.

EDIT:
In the example attached, I took the steepest gradient for section. In other parts of the routes of course there are gradients but are too short in distance, less than 1km.

The left side is going from Riesa to Dresden, and the right side is going from Dresden to Riesa (You gotta read it from bottom to top).

 

I do not know if someone told you that, but:
- The Train Weight does not neccesesarily seit the PZB-Mode and the Bremsstellung. you can run Trains far more Heavier than 1600t in P(G/P). The 1600t are only a Factor if your train Consists of Wagon-Units (Like the double-Container-Cars Sggmrss). In that case the Train has to run in G in order to avoid inadmissible loads on the articulated joints within the wagons.

- you don't have to deduct 25% of the braked weight for trains that run entirely in G. Those 25% are only deducted on Vehicles in G in Trains that run in P.

Despite that you´ve made a pretty good job with the Spreadsheet.

 

So you are saying that all the intermodal trains using the Sggmrss wagons should run in "G" mode with a max speed of 90km/h?

 

If the Weight of the Car-Train (Train-Weight excluding the Loco) is exceeding 1600t, then yes, you need to set up the Train to run in G. Since there is no Intermodal-Train that heavy (at least not that i am aware of) you won´t need to do that

 

Sorry I missed that detail, it's pretty late here, that makes a lot more sense thank you

 

That would imply that the table cwf.green posted for brake modes (depending on train length and weight) is only applicable for those types of cars. Is that what you‘re saying? If so, then how is the brake mode along the train determined for trains with only conventional cars?
