Downloaded - UKTS-15007 08604 'Phantom' BR Class 08 needed for a Great Eastern Activity

After testing I cannot find a way to get the engine to move!

I used a different cabview because FileID 10937 cannot be found.

If anyone could test the attached file it would be much appreciated, Thanks Graeme

Hello Graeme,
The old MSTS file has an impossible mixture of air brakes and vacuum brakes.
I have attached a new file for a vacuum braked class 08 - hopefully it will work for your activity.

Darwin

Thankyou Darwin, works a treat, I am sure this problem will arise again so I'll have to study your clever alterations.

I haven't had chance to test it on the activity just yet as there are about 60+ additional stock requirements to be checked before I can begin.

Much appreciate your time and skills, Thanks Graeme

edit: I noticed the usual smoke settings are not available, I generally use the ones below, how do I calm down the vast plume when the engine starts? Thanks

DieselSmokeEffectInitialMagnitude( 0.1 )
DieselSmokeEffectMaxMagnitude( 1.0 )
DieselSmokeEffectInitialSmokeRate( 0.1 )
DieselSmokeEffectMaxSmokeRate( 1.0 )

You could try reducing the size of the exhaust opening Exhaust1
(
0 3.96 2.95
0 1 0
0.25
)
Perhaps make the last line 0.20 or 0.15 see what looks right.
You might also try adjusting the following lines

IdleExhaust ( 5 )
MaxExhaust ( 50 )
ExhaustDynamics ( 10 )
ExhaustDynamicsDown (10) I have not experimented with these yet, so far concentrating on brakes and power.

Also if you have a suitable dieselsmoke.ace file you can adjust the exhaust colour with
ExhaustColor ( 11464650 )
ExhaustTransientColor ( 11141418 )

[X3D]

I changed the following settings:

(
0 3.96 2.95
0 1 0
0.30 - This setting tends to billow out the smoke which I prefer so I increased it from 0.25 to 0.30
)


IdleExhaust ( 5 )
MaxExhaust ( 50 )
ExhaustDynamics ( 1 ) These last 2 sorted out the large smoke cloud effects, changed from 10 to 1
ExhaustDynamicsDown (1)

Thanks Darwin for your insight.

Just found the same issue with a Class 40 D200, looks like I will need to figure out a template of some kind, if that is even possible?

Maybe a copy/paste of the existing Great Eastern MT_DD_CLASS_37 eng file, then edit the model names etc?

[darwins]

For any vacuum braked diesel I would suggest the following treatment:
(1) Delete all reference to any brakes in the original eng file.
(2) In the "wagon" section of the file put
BrakeEquipmentType ( Vacuum_brake, Auxilary_reservoir, Handbrake )
BrakeSystemType ( Vacuum_single_pipe )
MaxBrakeForce ( x )
MaxHandbrakeForce ( y )
BrakeCylinderPressureForMaxBrakeBrakeForce ( 21inHg )
MaxReleaseRate ( 4.0inHg/s )
MaxApplicationRate ( 3.4inHg/s )
**You will need to calculate suitable values of x and y for each loco. Y is easy just put approximately the loco mass in tons as a brake force in kN so a class 40 is 133t-uk so MaxHandbrakeForce ( 130kN ) is about right. For x you need to know the brake % or brake force. So if I look in the diagram book, it says brake force is 64% of weight in working order, so 64% of 133 tons is 85.12 tons, to get a brake force in kN for any loco with cast iron brake blocks mulitply this figure by 4.98 so that gives 4.98 * 85.12 = MaxBrakeForce ( 424kN )
(2) In the "engine" section of the file put
Comment (*** Braking systems ***)
BrakesTrainBrakeType( vacuum_single_pipe )
BrakesEngineControllers( Train )
ORTSBrakeServiceTimeFactor ( 1s )
ORTSBrakePipeTimeFactor ( 0.05 )
ORTSBrakeEmergencyTimeFactor ( 0.1s )
TrainPipeLeakRate ( 0.04 )

Comment (*** Exhausters ***)
ORTSBrakePipeChargingRate ( 1.80 ) Comment (* creating rate for RELEASE only theoretically should be 0.60 *)
Comment (* ORTSBrakePipeChargingRate = 0.12 for RUNNING - maintaining rate *)

Comment (*** Brake Valve Combined ***)
TrainBrakesControllerMaxReleaseRate ( 12inHg/s )
TrainBrakesControllerMaxApplicationRate( 4.0inHg/s )
TrainBrakesControllerEmergencyApplicationRate ( 25inHg/s )
TrainBrakesControllerMaxSystemPressure ( 21inHg )

( 3 ) And finally in the engine controllers put something like:
Brake_Train ( 0 1 0.1 0.3
NumNotches ( 5
Notch( 0 0 TrainBrakesControllerReleaseStart )
Notch( 0.2 0 TrainBrakesControllerRunningStart )
Notch( 0.3 0 TrainBrakesControllerSelfLapStart )
Notch( 0.4 1 TrainBrakesControllerApplyStart )
Notch( 0.9 0 TrainBrakesControllerEmergencyStart )))
Make sure any reference to independent brake or Brake_Engine is deleted as locomotive brakes do not function well on vacuum braked locos in OR and can cause problems.
I have uploaded some example replacement eng files for diesel hydraulic locos and first generation dmu to UKTS. I hope to soon add some for electric locomotives, after which I might consider doing the same for some early diesels.

Thanks for the information Darwin, I'll experiment with some of the .eng files later today.

I noticed you have a few uploads on UKTS, will be trying the LYR - Heartland - 1920 v2 route, didn't notice it on the main routes list?

Thanks again, Graeme

[darwins]

LYR Heartland is all Brian Bere-Streeter's work - I take no credit for the route, I simply uploaded it for him because he is finding it very difficult to upload large files to UKTS.

[X3D]

Hi Darwin, I followed your alteration guidelines and successfully brought the Class 40 D200 to life.

Thanks
