Stanier 8f Wheelies

Discussion in 'TSW General Discussion' started by dangerousdave, Jun 17, 2022.

  1. Are the front wheels of the stanier 8f ment to be leaving the rails? The bounce is a bit more aggressive than usual!

    The wheels of both trains leave the rails. It's bouncing up and down like crazy like there's no weight especially at speed
     
  3. Yea the both had a bit of bounce to them but today it's much worse. We'll it appears that way.

    I thought the train was gonna leave the rails at one point.

    Thanks.

    How fast are you going dangerousdave and are you able to record video?
     
  5. I wasn't going that fast. Around 40 mph. I'll do a vid later.

    The first few days it definitely wasn't doing it. It had some up and down movement, what you would expect, but now it's a lot worse.

    Interesting - any particular service where you would expect I'd see it and approximate time in - or is it anywhere?
     
  7. I first noticed it on the worst winter of all.

    Not far into the scenario. As soon as you reach around 40 mph.

    Yeah I see what you mean. This is absolute guess work but I suspect the wheel sets aren't modelled as sprung - when the pilots lift the driving wheels do too - at least the front ones. Looks like the entire locomotive is trying to stay within one vertical plane and as the track undulates its struggling to match it.

    On a real locomotive each wheelset is independently sprung so you would expect each of them to jog up and down as needed to match the track profile.

    I'll send in feedback about it. I had noticed it happening in the past but now you've made me look in detail its interesting.

  10. Yea I think you are right about the suspension on wheel sets being non existent. Correct me if I'm wrong but aren't the pilots ment to have quite a lot of suspension travel, so they stay on track to prevent derailments when bouncing like that?

    During the rescue scenario, as I was dropping the defective Jubilee into the shed near the end of the scenario, I noticed that its tender was rhythmically lifting up and down off the track while it was still coupled to the 8F and both were stationary. I’ve also posted elsewhere about the amount of shifting around of the external cameras and have come to the conclusion that there is a lot of artificial movement introduced to the trains to simulate how bouncy it would be in an old steam train but it has unwanted artefacts such as these issues.

    Genuine question, as I am not knowledgable at all on steam trains, but isn't the effect a bit exaggerated. At 50 or 60mph the 8F feels like a rollercoaster. Am I supposed to just go slower?

    It seems a bit overdone to me but I don’t know how bouncy the trains were back then.

  14. Yes I have noticed this. When stationary the loco and tender are moving about. But with tsc the trains are never stationary even though in games the player is usually stationary and its the terrain that's actually moving. So I guess I just expect it now.

  15. They do bounce. Especially when pulling a heavy load. As the weight of the wagons pulls on the coupling it does tend to lift the front of the loco a bit. That's why they have pilot wheels. But the pilot wheels are ment to stay on the track, not lift with the train.

  16. As for speed. I'm not familiar with track limits back in the 50s but today a lot of lines have 2 speed limits. One for passenger services and one for freight (depending on what type of freight) this is not implemented in tsw. There's been a few times I've past a speed board at line speed but with a 45mph freight limit and not been points penalised for it.

    On sos I never usually exceed 45mph when driving a freight train.

    I'm sure someone knows the answer to the above though.

    Another thing to look at for is the little gadget that shows acceleration or brake force on the hud. If it starts bouncing up and down your getting articulation and should reduce power.

    This is due to the fact that the rails are completely flat but the loco is behaving like the track is not flat. Hopefully more realistic track rendering in the future can make this look more realistic.
    If you play a game called Diesel Railcar Simulator there will be an update soon that will simulate uneven track quite accurately.

    DRS simulates all aspects of movement, far better than TSW or TSC.

    It sure does IKB and did so from the inception of the game.
