Default Stock Physics Updates

The goal of a real world simulation is to have the most accurate physics possible, discuss both the way that things work and the way that they work in the simulator as members try to map the two together to refine the simulation.

Default Stock Physics Updates

Post by RSAdam »

Hi All,

I am coming to the end of all the planned collision box and coupling updates to the default and free download stock for Rail Simulator, and am opening the floor to any other data changes people would like to see included.

I have already included fixing the graduated release of brakes on the HST and 166. Is there anything else along similar lines with this or other stock that the community would like to see implemented?

Cheers

Adam,

Yes please:

1. Graduated release of the train air brake on the Class 47 and Deltic with air braked stock.
2. Notched / Stepped brakes on the Class 166 and HST.
3. Bogie brake gauges to respond to the loco brake on the Class 47 and Deltic.
4. No2 engine not to "magically" start at 30 mph on the Deltic but to be running when No1 engine is, assuming that separate stop/start of more than one engine is not possible.

Thanks for inviting requests.

I find that the acceleration of the Class 66, at least in simple mode, is frightening.
Perhaps this is how it should be but could you take a look at it?

Thanks

Hiya,

If you could provide some data to backup your request that would be great. Otherwise I can only assume this is a case of the performance not be as expected rather than being technically wrong.

Ah. Just a feeling based upon the response of other diesel and steam engines within the simulator. The lack of fine speed control makes it unwieldy unless heavily loaded, and unlikely to be driven much by me. It feels a bit like driving a car with the accelerator jammed open. I expect it's better in advanced driving mode, though I've not tried it.

You obviously feel there's no problem with the 66, and I don't recall other people mentioning it, so perhaps it's correct and it's just one engine that I can't get on with. Pity though because they look nice parked on the sidings.

:-?

Well Im happy to make changes if people can provide data for the changes. Otherwise I only have the data that was collected during development of RailSim, so Id rather not deviate from that based on users feelings, because there is no confirmation that such guessed changes are accurate or not.

I suppose what needs to be questioned is not the accuracy of the data but how the data is handled in Rail Simulator? I don't know much but are the physics in Rail Simulator pretty damn close to real life when using the real figures?

According to all the real drivers Kuju had testing RS before release last year, as well as feedback from drivers we have spoken to at shows, things are pretty accurate. We have had comments back about difference of oppinion between the community expectations of a trains performance and the real performance as fedback from real drivers.

Hence why I will really only act on proven technical inaccuracies in the data as it stands. To this end I can confirm we have had feedback on areas that are wrong, and I have since corrected these for inclusion in this physics update - Notched and graduated brake release on the HST and 166 being a prime example.

I've heard the HST's performance is very realistic so does that use bang on accurate data? If so, the simulator must be handling it fine.

Hi Adam

My gut feeling no data sorry :D
Is that friction element for steam loco's is too high... 30 wagons on a 1 in 50 grade would have even a 9F stuggling for grip on a wet track

as an experiment I halved the figures and got occassional slip... I did not try with varying loads etc or any scientific approach.

Hi Andy

The number 2 power unit is running, it is not used until the speed hits the magic 30 mph, then it matches the rpm of number one.

Hello Derek,

I already tried to discuss about braking setting in RailSimulator.com forum, but you never answered... One more time, and this will be the last, I will reinstall RS to see what can be done...

Glyn,

If No2 is running then surely the No2 Engine Stopped light should not be lit below 30 mph? Can't find my Deltic book right now but I believe that the unequal engine loading is due to ETH being supplied and the affected power unit would be the leading one, not always No2. Also the point at which they both ran at the same speed would surely depend on generator voltage or current, not loco speed. If no ETH is in use then I think both engines would be equally loaded.

Sorry,
You are right, they where working last time... :oops:
