I have this issue in TSW2 and it caused 2 derailments and many strange sounds already. Yesterday i read here its still present in TSW3.
buffers are no longer correctly simulated and the hard hit between buffers pushes the train which can cause derailment.
Can you share a video of this? Some repro steps so I can get it in front of someone? This should have *improved* not gone backwards...
Hi Matt. At least it is still in TSW2 and yesterday someone here said the problem was also still in TSW3. There was much talk here in the Forum about the buffer issue after the SOS patch: https://forums.dovetailgames.com/threads/buffer-related-problems.55341/#post-493691 This issue is also on PC. The issue is: You can hear the buffers slapping hard together (something you could not here before the SOS patch) This seems to affect all locos on all routes. THis "slap" can cause sudden acceleration or even sudden derailment. Im sure the bug has already been reported to DTG. DTG JD said in this topic it has been flagged so i guess DTG has already the info they need about this bug.

Ok what I could use then is some clear examples and videos from the current builds of 2 and 3 - then I'll go back to the physics engineer that worked on the couplings. I know it sounds tiresome to ask for examples in the current build but it will make things go quicker particularly if they are unable to repro the issues in the debugger as the first feedback will be "probably fixed in latest build, please retest" - so let's short circuit that. I am aware of a derailment issue under braking which is much more pronounced in the wet but can happen otherwise - where for some reason the bogies are lifting a little off the track and this causes the engine to detect them as derailed - at which point, chaos ensues since a derailed train switches physics model. In reality, they aren't derailed of course, something else is going on - this specific issue is being worked on at the moment and may or may not be related to the derailments being seen here. E.g. the changes to couplings / buffers that seem to have extended gaps (judging by one of the posts you linked) may mean that as you now apply brakes the wagons bang together more and this may cause them to lift briefly enough to be considered derailed. If I can get some reliable repros then they can run them in the debugger and see exactly what's happening, which will make it much quicker to fix. Matt.
Is this the cause for the derails in SPG, when you're going smoothly down an incline and the cars jerk and derail out of the blue? https://forums.dovetailgames.com/threads/derail-bug-not-fixed-on-sand-patch-grade.57064/ If so, I'm very happy to hear it's being worked on, as there hasn't been a peep on this subject in quite a while.
Hi TrainSim-Matt, your forum is full of threads referring to this nasty bug (and the outcries for a fix!). I have a hard time to believe you didn´t notice them: https://forums.dovetailgames.com/search/28292039/?q=derailment&o=relevance https://forums.dovetailgames.com/search/28292103/?q=derail&o=relevance Earthquake in Paddington? https://forums.dovetailgames.com/threads/derailment-take-number-974158761443-or-so.58491/ Look what you did to the coupler distances:
Hi Matt, how much work would it be to have an option to disable derailments in the options? As a workaround until you guys figure out what's going out with the bogies? Because the only time I experience derailments is when this bug hits, as I try to drive within the speed limit. And I guess it's the same case for most of the people here. As of the issue, most of the time it tends to happen (atleast for me), when the loco is the main braking force and the train is bunch up. Maybe an incline change, where one car is level and the in front is inclined, coupled with heavy force comming through the coupler makes the total force enough to lift the level car little bit up? As the force might point little bit upwars, becaue of the front car tilted to follow the downhill incline?
There seem to be two derailment issues: One with the brakes on heavy freight and another one with the buffer/coupler distances. Below the famous 83127 Service on MSB. The fun part is that this worked already until the *damned* SoS Patch (1.86 if my memory doesn´t fail) In the screenshot you can see that this service has been completed successfully once upon a time. Now it does what the video shows.
I really feel DTG need to add some players to their testing team who would sign an NDA and just play the game before it’s released. No set testing schedule, just simply play the game as people play it. A mixture of people very knowledgable about the trains involved and people with an eye for detail would help things so much IMHO. So many things are so immediately obvious after every new release that you do have to wonder if the QA / Beta testers are doing things whilst sleeping. I often sit looking in complete disbelief at how these really obvious things seemingly slip the net. It even comes down to simple things like how on SEHS extended the majority of services in a Journey chapter about driving at night are set in the day time. I mean, come on! It seems that whatever they are doing at the minute is not working. Whilst asking players to take time to video gameplay and send in details of a bug that has existed for ages, I’d hope Matt will be going to his testers and asking how they seemingly collectively missed something so long standing and so obvious yet again.
This would not help because the buffer bug screws up the physics anyway. They need to fix the buffer bug. It was reported to them half a year ago!
The way I understood it, there are two separate defect. One is the buffer one, and they definitely need to fix that. The other one is what Matt described, that under heavy braking, especially in wet conditions, sometimes the train just derails. This bug has been in the game for a much longer time that Spirit of Steam (like initial TSW 2 release), I faintly remember it also occuring during one of the TGV streams, when Sams train just went flying during heavy braking.
This extends to other issues like the broken scenarios or runs in Journey mode - Chopper And Change the most memorable one that remains unresolved to this day. I can appreciate not having the manpower to run every train in the timetable but all scenarios and anything included within journey should be fully beta tested. For that matter the mystery SPAD's on SoS, which were occurring before the 1.86 patch and then carried forward to TSW3, too. I know it can be hard to test what you create but so far as the actual DTG employees are concerned, that is what you're being paid to do!
Hi Matt, This was during my livestream last night on Riesa Dresden. I was running 0815 service from Riesa - Dresden in a standard BR185. The Date was set at October 1st 2022. I did set it originally to foggy but it changed to clear as I pressed continue. I was 8.3 km from Dresden Mitte in a heavy thunderstorm and the train went NOPE!! See below. https://youtube.com/clip/UgkxRahxKhaMKy7sjQTWKjZunxrE8cs22Qhk I wasn't under braking although the split second before I derailed I started to accelerate from 75kmh to 76 kmh. I was also pretty erm shocked lol. Enjoy.
Have you tried it after the latest patch? I played it yesterday and it finally works again on XSX. The SoS patch should've been rolled back immediately. It ruined a lot of things and took away much of the fun I had with the game.
Would be nice, but no. The MSB Video was shot this morning with 1.91 installed. And I´ve just had a look at Diesel Legends and .......... *SIGH* ...... guess what. And I´ve checked the couplers on TVL ......... well. At least in TSW2 on PS4 the last patches did not address these issues.
Ok. So just to clarify a few things from my side. It's TSW3 on XSX. DB 83127 along with DB 83115 in TSW3 inherited the instant derailing from TSW2 introduced in June but became playable again with the latest patch.
OK, that´s what I thought. Let´s see if DTG fixes this in TSW2 as well. Sadly enough they transferred this over to the "new" game.
I agree with you, bugs have been improved, but the game experience has not, this has gone backwards since the glorious SOS patch. The SOS patch should be rolled back, rather a single route where the couplers don't work properly than a whole game that frustrates you during the startup process because you don't know if you're going to derail, when you're going to derail, where on which route with which train you're going to derail. Look at this, do you think this is cool? Authentic? Can you count this as fixed in good conscience? I have endless other examples, this is a botch, not a fix:
I honestly are curios how DTG could not know about these massive issues when they were reported to them right after the SOS patch by a ton of people and even acknowledged as "on the list" a few months ago.
There are only two possible answers: either they are tracking issues that they've acknowledged and have just decided they're not worth spending the resources to fix, or they simply don't have a good system in place for both tracking issues AND ensuring tracked issues are at least regularly checked, if not addressed.
I reported this in another place in the forums. I was under the impression this one was fixed. Alas! It seems not. Haven't even been near SPG as it's too disheartening.
And they seriously expect us to purchase more? I know all games have bugs, but this is getting ridiculous.
To be honest its the first time I have experienced that sort of "derailment". I've had the steam loco derailment under braking but not the sort derailment I showed above. Hentis
There's a new thread going to be started in Technical Reports shortly for collating feedback in one place, I would very much appreciate if you could put examples, screenshots, videos etc in there once it's started by Alex. I'm also interested in the couplings that aren't right in the screenshots above too - so more screenshots of couplers that look wrong along with an outline of what the stock involved is (ideally, the scenario/service used to recreate it to help people get to it quicker) - it's either a visual error that means little aside from lookign bad OR a sign of physics under pressure that could indicate the issue. We already have an engineer looking at derail issues, this will get added to the mix as there may be overlap / same underlying issue OR it may be entirely different, this way he can figure it out. As I say - hang fire and let's get it all in the new thread once it's up. Matt.
Hello everyone, as Matt has mentioned above here is a link to the new thread where we can compile responses about this issue: https://forums.dovetailgames.com/threads/derailment-buffer-block.60307/
