    Against my first impressions i have to say that after i drove the 218 on DRA, this felt way more "correct" to me and i understood why, compared to the like of the DB 642, i disliked it in the first place.

    I dont know if the suspension of the 218 has gotten an update, but it felt way more subtle especially over junctions. Not the "excessive jumps" but rather slow waving motions that made the impression of the loco being really heavy.

    The 642 in comparison felt like a tinned can over junctions and therefore gave the impression of being very light weight.

    Will test it on other Trains though, but for the 218, i actually really like it!

    In my case I hate this loco. The buzzing is unbearable and makes me hate this loco series. Yes I have heard the original sound and it is no way near this bad. I don't know why they create new variants of the loco and yet don't fix the broken sound

    I think it’s quite good on the öbb 4024, I can’t see it on the db 185 though or the BPO 47 for whatever reason

    It's actual physics.

    We programmed a dip in the joints at junctions, and the wheels are riding that dip because physics says they fall into the dip. Everything that happens after the dip is physics with springs and such.

    It does vary at different speeds because just like in reality, and because physics is being used, if you go faster over a gap, you notice it less. Go fast enough (and its not really that fast) and you won't really notice it much at all.

    What you will notice as you go faster though, is the way the suspension reacts to changes in the track direction etc, which will cause it to rock in response. Again, physics. No animation.

    Faking this with animation would be much harder than using the physics system.

    There is a programmed "roughness" effect that a route developer can tune per piece of track, some routes are more "bumpy" than others (it's not visually seen on the rails, but used to make the wheel-ride a bit bumpier as it travels along). Because the wheels are moving here, so the suspension is reacting to it as well, which means bumpier tracks will make it feel like the train is bouncing around more, where sleek modern tracks likely will have smoother roughness setting and bump around less.

    All physics, all dynamic.

    Matt.

    For the time being, until a menu option is available, what would I need to change in the GameUserSettings.ini to disable the suspension?

    Default value is "Improved" - what are other valid options? Edit: Had a quick look into the .exe, the only other option is "Standard". It doesn't seem to make a noticeable difference though after a quick check with the 801 at 125 mph.

    So in conclusion, dialling back the Camera Sway to 50% gives a good result for me personally, as it's very subjective in how you would counteract the motion with your body. (I remember my first time riding a horse, if you know what I mean...)

    By "bouncing" you mean up and down? Cause for now game is really lacks of swaying in horizontal directions.
    On many IRL videos you can see how swaing the train on the worn out switches. Sorry, I can't find this P42DC video, where the whole train flying trough the switch with massive deviation from left to right.

    For a real bouncy ride do a custom service on SOS or peak forest

    I enjoy bumpy sections of track. It’s realistic. Especially here in North America. Some locations will give an amusement park a run for its money. Like on SEHS running southbound between Hoo Junction and Higham. Trains bounce really good through there (even trains without suspension physics).
    - On BML, the fast lines through Streatham Common is the bumpiest location I know in TSW. Though the posted speed limit is 70MPH, I’ll sometimes come in a little faster for maximum effect. Haha Love it!

    Oh! The Amtrak Southwest Chief flying through Commerce station in California. I’ve seen that video. That thing was rocking and rolling!! Rare to see a modern day passenger train (superliners at that) flying on rough track like that.

    Don't know if this is related to the latest update, but I just ran the Royal Appointment scenario on Peak Forest and the double-headed Jubilees were like a pair of bucking broncos (very noticeable in both inside and outside views). The steamers were lively before but their behaviour now seems unnatural, as if they were running along a long-disused freight line.

    As an aside, this scenario, although enjoyable, has little credibility; what operations manager would send a deliberately dawdling light engine ahead of a royal train... heads would definitely roll!

    Well the Jubilees had exaggerated pitch and sway going back to SoS so anything further just makes it outlandish.

    And yes I definitely agree about the Royal Train. It was always required to be double blocked, even if that meant retiming other services or regulating a preceding slightly late service out of the way. Except in an outright emergency, or normal signalling (junction or terminus approach), the Royal Train should never see anything other than green signals.

    I tested all the rolling stock with suspension. Overall, I had very positive impressions! The only thing I noted in my preferences is that there is not enough bouncing and swinging on the DB BR 185.2 (it goes very smoothly) and the twitching at the turnout intersections on the 66 and 47. I really like the suspension on the 218.

    For me it doesn't work at all. When on the Class 66 I see the suspension working on the outside, but I don’t see it working on the inside, then on the 185 there is absolutely no movement either inside or outside. Restarting the game do nothing. Vorarlberg 185 doesn't have any suspension in my copy of TSW. Wagons wheels are bouncing, loco - nope.

    I thought it was just the Salzburg 185 that got it? To locate the Salzburg 185, I believe you have to select the railpool 185 in menu and then choose the Salzburg one… for some reason it’s under railpool 185

    I notice the trains jolt quite violently when going over points. Is this realistic?

    EDIT: ScotRail Class 380 & LNER Class 801 Azuma

    Aaahhh... My fault. For some reason I thought they added suspension to the Vorarlberg version. I don't have Salzburg, so can't test it.

    One aspect of the suspension i enjoy is that it provides a little feedback on passenger comfort, which is otherwise completely absent in TSW.

    Hitting a set of points too quickly now (even if not technically speeding), i'm like, "oof they definitely felt that one".

    It's a nice feature and looking forward to seeing it on more trainsets soon. Since USA didn't get any love in the first round, i'd love to see LIRR2, NYT, and Boston up next.

    I thought the opposite was true... going faster kept the wheels from going all the way into the "dip", making for a smoother ride at higher speeds. Now sway...that is where you have passenger discomfort because at higher speeds the carriage "rocks" more.

    Now imagine the old routes under steam that were even rougher and with no suspension....

    Guess i was thinking more about closer to stations, especially larger ones with lots of tracks crossing paths- like approaching Glasgow Central on Cathcart for example. At least that's where i've noticed the vertical suspension bumps the most.

    I mean.. that makes sense. There's a lot of switches which are the least smoothest parts of the track. I tend to avoid the heavily congested commuter routes, so it's far less noticeable in rural arears and with freight runs. Is it more "bouncing" or "swaying"?
    I don't have Cathcart.

    It should be a mix of both irl but in game there’s a lot more bouncing.

    I wonder if turning up the "headsway percentage" would increase the horizontal movement compared to the vertical movement. I've had mine set on 150% fwiw.

    Hopefully at some point DTG will allow more granular tuning of the suspension components.

    Cathcart/380 def seems more of a vertical bounce but that was at slow speed coming out of Glasgow
    So I need to see what it’s like on other parts of the branch

    It's much more subtle on the smoother bits of track. On the stretch from Newton to King's Park it's only barely noticable for me.

    Edit: to an earlier point in the thread- it kinda makes common sense that the effect would be more noticable on an EMU than a freight train, since they're WAY lighter vehicles, right?

    Mentioning physics, you might want to go and try driving a service out of Crewe on Spirit of Steam. I think the update has had an negative effect there, it's now rather nauseating to drive due the extreme shaking. I know the route had a track roughness factor before, but it seems to have gone extreme since the suspension update.

    Try "The Manxman" service with the Jubilee.

    I've seen others mention it has affected Peak Forest as well, though haven't tried that myself.

    I’ve got my headsway set to 80% and both the Class 47 and 142 are still pretty dynamic. I think this is something to do with either the way the trains have been set up or the track itself

    Yes we have identified a weird side effect where it seems steam engines are reacting to joints in strange ways that weren't intended.

    Testing a fix.

    Were steam engines even tested? Since the drivers are fixed in a rigid underframe, and only eventual bogies can swivel and bounce?

    I played an 8F service on Spirit of Steam after the update and the loco was moving around in a very unnatural way. I haven’t noticed that before so I think something in the core update may have affected things it shouldn’t have. And indeed as I was typing this Matt has replied saying it has, so there we go.

    They were always swaying around a bit more than you would think, albeit I noticed that with a Bossman Black Five on the S&C in TSC the other day, too. However good to hear the extra issue is identified and being fixed,

    I wouldn’t get your hopes up. Sounds like it’s purely to address the suspensions anomaly introduced with the latest update.

    Tried Cathcart again, did a full run this time. Horizontal movements seem to definitely be there, much more noticeable hitting a junction while on a curve.

    If you try service 2N28 in the 4 car set, you’ll see what I mean when you roll into Pollokshields East… you’ll hit the junction while rounding the curve at about 25

    Also got to try out the 185.2 on Salzburg-Rosenheim. The vertical effect is more subtle, but definitely there- i honestly couldn't notice the suspension effect on the Laaers autoracks i was pulling, but the running sounds for them seemed a little "richer", maybe? Like more rattles and squeaks? Are sound triggers tied to physics at all? Could definitely be my imagination though.

    Anyway, all in all i'm really enjoying this feature.

    Gonna try the Class 66 next i think.

    Hmm, there's a scenario. Nitroglycerine that's needed to blow out an oil well fire must be carried on an old train over old, uneven track.

    The 142 (and to some degree the class 47) would require major rework of the underframe/bogies to correctly animate the springs and axle boxes. I do not think however it will be a priority for JT/DTG, which is a shame but who knows, perhaps one day.

    Im getting a bit confused, yesterday I've celebrated the suspension on the 218, now im on a Service on HBL and it feels i have no suspension at all.

    Also: why is the ÖBB 4042 listed 3 times ? I though the suspension physics are linked to the Trains themselves?

    A clearer statement which Routes and Trains will get it would be good. I feel like players waiting for the Flying Scotsman to get her suspension (the wagons already got it) but afaik thats not hoing to happen.(?)


    I also have the feel that the feedback from us and how we feel about it is heavily related to where we live and which trains we regular tend to ride with.

    I live in Dresden, normally the Tracks here are on the smoother side, especially Mainline and S-Bahn Tracks, beside some particular places. So the jumping over junctions is something i normally not experience as a passenger here. (Exception is one Spot on Dresden-Altstadt coming from DD-Plauen, there is a junction where the trains really shatters over it)

    Given the feedback here, i have the impression that feedback from UK hints to general more bumpy rights there (not saying Germany has better rails but thats what i get from the this thread) but its hard to judge as someone who has never ride a train there.

    Though looking identical, they are different "versions" of a train, each bundled within their route. That's why you see only the 185.2 from Rosenheim gets updated, when others have not.

    I wonder what the difference is. outside is the same. no new functions. destinations are in the route file, and you can't even put a destination in because apparently that function is gone from most newer trains too for some reason. is there a different interior?

    Mainly code difference I guess. Like in the semmeringbahn 4024 you can no longer adjust cruise control speed with your controller. Or in certain cases they simply make a copy of it since certain platforms doesn't allow DLCs sharing files, as well as preventing "fix one bug on one loco, need test on every possible route" problems.

    ah fair enough. I cannot wait for my entire rolling stock library to become like the dosto's. all 7 individually broken or working on one route or another. some unplayable. but not to worry. in the next route you'll get a new one that will work for about 2 weeks after the patch and then something breaks it again.
