BB25185, BB25186, BB25236 sound

The BB25185, BB25186 and BB25236 locos that are required for activities on the Haute Savoie need a couple of small fixes so these locos' ENGine files can find their SMS sound files.

There are a couple of ways to keep MSTS happy: we can either edit each loco's ENGine file to correct the name of each SMS file in that loco's Sound folder, or we can simply use Windows Explorer to rename the SMS files to what the ENGine file expects to find. Let's do the latter.

Let's say we've installed each loco in its own folder so we'll have folders BB25185, BB25186 and BB25236.

If you do a quick check with Explorer, you'll see that the BB25236 folder doesn't have a Sound sub-folder, so the first job is to create it.

You may have noticed that the ENGine files for both BB25185 and BB25186 refer to sound files BB25236cab.sms and BB25236eng.sms in their Sound sub-folders. So now use Windows Explorer to copy both of these SMS files to BB25236's Sound sub-folder (note we've got the correct file names!).

Now all we need do is go into each Sound sub-folder of BB25185 and BB25186 to rename the SMS files according to the loco's name. That is, a check in Windows Explorer should leave us with:

  • BB25185 will have SMS files named BB25185cab.sms and BB25185eng.sms
  • BB25186 will have SMS files named BB25186cab.sms and BB25186eng.sms
  • BB25236 will have SMS files named BB25236cab.sms and BB25236eng.sms

Re 446 Tesa

Re 446 Tesa at Geneva station.

web•TrainSim chose the Re 446 Tesa-liveried electric loco from the SBB & Re 4/4 loco pack (SBB_Re440_&_SOB_446.zip, 18-Oct-03, 20.461Mb, from theTrain.de) for activities on Haute Savoie but expects similar fixes will be needed with the other locos in the pack.

It seems the author for these locos used an ENGine file from a diesel loco so the notches need removing from the throttle. There are a couple of other fixes to make the loco more prototypical and compatible with the Raildriver control. So fire up WordPad or your favourite Unicode text editor:

Corail carriages wheel radius

Corail carriages in the livery of TER for the Rhone-Alpes.

While checking something else, web•TrainSim opened the WAGon files for one of the Corail carriages and saw an incorrect (and difficult to imagine) value for WheelRadius - it was set at 0.89m which means a diameter of almost 1.8m!

You won't see any difference when fixed, but the carriage should perform more prototypically at braking.

So while listening to some music, open each WAGon file in the SNCF_Corail folder in WordPad or your favoutie Unicode text editor; these are the first few lines:

    ..............
Wagon ( corail+_A10tu_v200
   Type ( Carriage )
   Comment ( ** 07-Jan-04 : BMH : WheelRadius put down to 0.40 m.  ** )
   WagonShape ( corail+_A10tu_v200.s )
   Size ( 2.825m 4.05m 26.4m )
   CentreOfGravity ( 0m 2.025m 0m )
   Mass ( 42t )
   WheelRadius ( 0.40m )
   InertiaTensor ( Box (3m 4.5m 27m) )
    ..............

At this time web•TrainSim hasn't a prototypical value for WheelRadius but 0.40m is more reasonable than the original.


SBB IC 2000 trainset

IC2000 Bt steering car is on the left of BB36002 at Geneva-Cornavin station.
IC2000 Bt steering car is on the left of BB36002 at Geneva-Cornavin station.

There's a problem with the steering (driving) trailer IC2000Bt.Eng in the SBB IC2000 double-decker trainset, SBB_IC2000_V1_0.zip (24-May-03, 3.137Mb) from TheTrain.de and it shows up when the IC2000 trainset consist is loeaded into ConBuilder. By sheer luck, web•TrainSim found an update to the IC2000Bt.Eng in a download from www.hothost.ch/ts/home.html in IC2000V2.zip (29-Dec-03, 3kb).

To make the IC2000 driveable from the steering trailer, we need a cabview; web•TrainSim copied the cabview from SBB_ECre460 electric loco which you should already installed as part of the rolling stock required for activities on Haute Savoie.

When checking through IC2000Bt.Eng, web•TrainSim also noticed:

  • BrakesEngineControllers( "Independant(sic), Train, Dynamic" )

web•TrainSim changed this line to:

  • BrakesEngineControllers( "Independent, Train, Dynamic, Blended" )

which is the Re 460's - that means, too, that we can use Raildriver with the settings for the Acela HHP.

BB422217 electric loco sound & cabview

SNCF electric loco, BB42217, BB422217.zip (528kb, 22-Jun-03), is a required download for the Haute Savoie and is available from Henri Verpiot's rolling stock page. Henri's BB422217 is a repaint of Chris Longhurst's SNCF BB7200, (sncfbb72001.0Setup.exe, 1.36Mb, 30-Aug-03, from Christrains.com), and you only need the cabview folder containing bb7200.cvf which aliases the cab to the Acela HHP; sounds are aliased to the HHP, as you'll see below.

web•TrainSim installed the BB422217 into folder SNCFBB422217 and the Longhurst BB7200 was installed into the SNCFBB7200 folder.

Once you've copied the Longhurst BB7200 Cabview folder to the BB422217's folder, you can open BB422217.Eng in WordPad, or your favourite Uniocde text editor, and make the changes in red:
