For the last week or so I have been trying to determine what realistic loaded weights would be for the German freight wagons. Reading the print on the sides of the wagon gives you the empty weight and the load limit. However, even with this knowledge you do not know what a typical loaded weight would be, only the max weight. For this reason I have been trying to track down information on what loaded typical weights for each wagon would be, but it is quite tricky. I'll start with the "easier" wagons first: 1. Shimmns-t 708 and Shimmns-ttu 722 (Steel coil covered wagons). From my understanding these would typically have loaded weights that equal their max weights since the density of steel coils mean that you can never fill a wagon and still be below the axle load limit. So with this assumption in mind I think it is reasonable that these should always be around 90 tonnes when in loaded config. 2. Roos-t 645 timber transport wagon. With the help of the website dybas.de I found that this wagon has a load volume of 95 m^3. The print gives an empty weight of 25.2 tonnes and a structural load limit of 58.5 tonnes. Interestingly the real world wagons these were based on must've been used in Sweden because you can still see the D-axle load cargo weights for "GC" which is the freight company Green Cargo. From my understanding these were phased out in Sweden due to their low cargo capacity (virtually all Railroads in Sweden can handle 22.5 t in axle load and many are being upgraded for 25 t so the Roos-t max axle load of 20.9t is "wasteful" I guess). Anyways, I did some research on the density of raw/green pine wood and the most common number was 800 kg/m^3. With this density and a packing factor of about 80% (I calculated this with an assumed log diameter of 20 cm) the cargo weight would be 60.8 tonnes which means that the wagon is weight limited and thus a loaded weight can be assumed as the max weight of 83.7 tonnes. 3. The Falns 183 coal hoppers have a load volume of 85 m^3 and some googling gave me a density for lignite (aka braunkohle, the most common coal type in Germany) of around 1.3 x density of water (called specific gravity). This means again that the wagon is weight limited (85 m^3 * 1300 kg/m^3 = 110.5 tonnes) so a typical loaded gross weight will be the wagons max weight. 4. The Zacns tank wagon. This one is a bit interesting, and to me the most surprising. The UN-number on the side of the wagon (orange colored plate with one 4-digit number and a 2-digit number) is 1863 which I found out was the code for Jet fuel/Kerosene. The Jet fuel used in Europe is called Jet A-1 and has an average density at STP (standard temperature and pressure), according to Wikipedia, of 800 kg/m^3. Now the tank wagon in TSW2 is one of the smaller variants of this wagon with a load volume of 62100 liters. This means that a fully loaded (by volume) tank wagon has a cargo weight of 49.7 tonnes. Since the empty weight is 22.6 tonnes the gross weight is then 72.3 tonnes! This is nearly 18 tonnes lower than the in-game weight Now I'm done with the "easy" wagons. By easy I mean that information was available, I might still have made a mistake so I appreciate any input. 5. The Habbiins 344 covered van. This wagon is, according to dybas, able to carry 63 EUR-pallets. But what is the average weight of a loaded pallet? And how many loaded pallets does a loaded wagon carry on average? This is not easy to answer. I have found some conflicting answers to this question. I found a study for road freight carrying pallets that gave the average "Load factor" (average cargo load divided by cargo capacity in terms of weight) as 56-57%. The Habbiins 344 has a cargo capacity of 63 tonnes and an empty weight of 27 tonnes so if the data for road freight was applicable to rail freight the average loaded gross weight would be about 62-63 tonnes. However, I have heard from Swedish train drivers that these types of wagons usually are either fully empty or fully loaded and additionally that trains of these types of wagons are notorious for their crappy brake performance because the braked weight is quite low and the wagons are usually (again) fully loaded. Sweden is not Germany though, so I don't know how much this data point can be applied to German freight wagons of this type. It would be interesting to hear from any train drivers on this forum or maybe (if there are any lol) people working in logistics? 6. The last wagon I will mention is the Sggmrss 6-axle twin container wagon. It carries two 40-foot (I think) high-cube containers (which have tare weights of 3.9 tonnes and max gross weights of 30.8 tonnes). Here I'm completely in the dark. One approach to determine a reasonable typical loaded weight for wagons of this type and configuration is to determine the average weight of these types of containers, then multiply by two and add the empty weight. Here data from road freight should be enough since containers on container trains usually end up on trucks at some point during their journey. But I have not really found any good data for this either. A Swedish train driver I spoke with mentioned 75-80 tonnes for a loaded 6-axle unit but that was basically after I forced him to guess lol, so I'm not too satisfied with that answer. A gross weight of 75-80 tonnes is basically slightly less than the mid point between empty and loaded ( (29.5 + 134.5)/2). Anyone have any better ideas here?
