Atomic Systems

Remember, ideally cab sway is both track dependent and unit dependent. The blueprints are not yet optimised if it is not default content.

Take a look in the cab camera blueprints

Cheers Ben. So just cab model XYZ movement and no head movement? problem is I look out the windscreen and nothing moves except the window frame ( and obviously the rest of the cab ) - that's a very well compensated seat! Actually there might be a little roll, but it's not very evident. Is the guy modelled with his head on a stick, or just attached to the springs?

I think a lot of the violence of current cab sway is due to the track laying style of existing routes. Generally, there are no transitions, either for curves or for gradients. As a result, even a join from level to 1:200 is very noticeable, and entering even a 2km-radius curve at 125mph is very uncomfortable.

Some of the rest is due to simplistic physics in the train, eg. instant taking of power or brake settings, which would result in very high jerk rates. (Jerk is the rate of change of acceleration, which is the rate of change of speed.)

The sharp track geometry seems to have a highly negative impact on some of the couplings, too. I regularly seem to leave some of my train behind during "Autumn Leaves".

You're right about the track, but from vids I've seen it does seem a little too much. Except for a 142 where it's far too subtle

I'm sure we've got plenty of exploring to do on these new features

Cab sway on HC seemed quite reasonable but then I've only done the first two scenarios which have you stuck doing switching in the yard.

I have to say I love the feature.

I did wonder why the camera itself does not move though. After all, a human driver would need heroic control over their body to maintain a steady position while bouncing over rough track.
Mind you, I'm lucky enough to not suffer from motion sickness, adding more motion could make some users start having to reach for the sick bag. Not fun if your a sufferer.

Does anyone know if sway also exists on the "head out of the window" views? I tried and seemed to get mixed results, I got some movement in some locos but I wasn't sure if it was down to some other factor or not.

Hopefully we'll see patches start to come out that address the more excessive sway. In the mean time, I think I'll try a class 86 on WMCLN, it sounds like fun.

The camera does move, slightly; I think it might move in the same way the external body does. If you set up some really violent track you can see the horizon tilt a little. I'd like it to move a bit more, because it does take some effort to actually see it moving and the way the cab pitches around you'd expect the driver to get whiplash sometimes - but at least his head would move a bit more, but that could actually cause motion sickness if you're succeptable to it.

Hi people,

I think the cab sway is a bit nervous. When you turn the controller to the first step you will broke your seat becouse of unbelievable G-force. Trains starts very slowly, it's not realistic. And the same at braking. German stock with AFB is very funny. (it's a tempomat, which currently gives full throttle and full brake to keep the speed). Would be cab sway instead of cab bounce!
I didn't see any sway in outer views.

Hi all

It strikes me that this is one of those features that seems like a good idea but needs to be thought out a bit more.

Surely it would be realistic if the camera was to move rather than just the cab, at the moment although it give the impression of movement it does not seem 'right', everything outside the windscreen is static and the frame rocks from side to side.

Also the fore and aft movements seem to be way to aggresive. It maybe realistic for a sports car on a track but somehow I doubt that there are many trains that could generate this scale of g forces.

Just my thoughts

Randomly tried out "The Bristolian" scenario in Western Rails, with 6024 "King Edward 1", and the sway feels about right. Curves, points, acceleration, braking. None of it's overdone or too violent.

I like the fact that it's evident when "sitting in 1st Class" as well as when driving from the cab.

What i do not understand is why everybody is talking about 'cab sway' while it actually should be called 'head sway' aka ' head latency' . ( Ok, what's in a name, éh.. ? )

If only it *could* be called 'cab sway' !

With a correct 'cab sway' implemented we would see the scenery sway and jerk about a little bit. The immersiveness of being inside a hurtling along train cab would be upgraded 100% instantly compared to the current 'static' state of our beloved Railworks cabs. I can sure appreciate that RSC has been trying to do something about this 'static' state by giving us this 'head latency' feature but the cab, i.e. locomotive, is still stuck rock steady to the rails, still no virtual suspension, i.e. 'cab sway' to be aware of what so ever.

I know full well that you don't look a gift horse in the mouth ( i *did* buy the Horseshoe Curve and looked it in the mouth.. ) but i have been putting my hopes up for a *real* cab sway feature every since the first announcements about TS2012 appeared in the forums. I also know full well that such a feature ( the scenery swaying about and *not* the cab itself... ) would be very much more complex to implement than this 'head latency' feature. ( if possible at all without having to rebuild the Railworks scenery engine from the ground up ( if you pardon the pun.. ))

For the moment i'll just keep hauling my 66 wagons of hope from Here to Eternity and i'll be sure to always wear a helmet from now on.

Cheers,
Jan

Both the cab and the vehicle body physically sway. In the early videos, the cab sway was a little high and toned down a bit before release. Vehicle suspension is also simulated - this in fact managed to tone down the cab sway significantly by itself. Press shift + f2 and take a look back down your consist, particularly when going round corners or across points.

In my own opinion, it acts fairly realistically and believably. The let down is that default routes don't make use of easement or track unevenness (and it would be a tremendously large task to implement it on all default routes!), so the effect is somewhat limited until you hit a sudden turn or go across some points.

So we reached that point, when everybody post cabride videos to make their opinion stronger.
To avoid that, here is my suggestion: A switch which lowers (turns off) cabsway.

Imagine a 142...your head would be bleeding!
