BB 67439 tune up

From the cab, looking right.

Pierre Gauriat's diesel-electric BB 67400 loco, bb67400.zip (20-Mar-03, 3.65Mb), is available from ajtrainsim.free.fr. It includes a cabview and uses an early version of Belphegor's CC 72000 sound set. You'll find the ENGine file, bb67400.eng, in folder BB67400.

Florent Brisou's data sheet for the BB 67400 at Rail 21 was used for the specs amended below. Note this loco doesn't have dynamic brakes and Pierre forgot to incorporate an independent/loco brake.

CC 72000 tune up

CC 72000 on a test run away from Culoz towards Bellegarde (Rhone-Alpes route). Shame you can't hear Belphegor's sounds in action!

Bruno Terrien's diesel-electric CC 72000 loco, cc_72000.zip (1.7Mb, 21-Jan-02), is available from Simtrain-fr.org. The model includes a cab by Florian Barrallon and Estelle Pichodou.

web•TrainSim has used the updated Belphegor sound set, soundcc72000.zip (3.13Mb, 01-Aug-03), from Belphegor's site. Note you need to finish a little bit of cleaning up in the SMS files, cc72000CabGV.sms and cc72000EngGV.sms. Here and there you'll find a blabla preceding some WAV filenames so delete those characters. As well, there are some unnecessary "../../Gp38/Sound/ folder path names preceding the couple_auto WAV filenames.

   Comment ( **                   Use Belphegor's new CC 72000 sounds.  ** )
