    Unexplained? To Crash or Not to Crash!?

    Running Open Rails V1.5.1 stable.

    Created a simple activity for the North East Corridor V4 route running along the main tracks (not running along the secondary tracks to the west and north of these main tracks).

    From milepost 96, take a small consist to about milepost 66. Reverse consist into Aberdeen siding. Disconnect and leave consist at the siding. Drive locomotive back to siding at around milepost 76.

    Train consists of a DDA40X locomotive with seven coal cars. No other trains running in this activity.

    After dropping off the seven coal cars, and driving the DDA40X back along the main track, the activity crashes at about the same spot! Tried this activity twice and each time the crash occurred at around the same area of the route.

    Ran Route Riter three times in total for this NEC V4 route to check that this route was OK. Route Riter found a few sound source errors initially after installing NEC V4 route but subsequent scans by Route Riter didn't find any further issues with the route.

    Ran Route Riter again to check my activity for any errors, but no errors were found.

    On inspecting Open Rails error log report, I noticed that there was an external sound wave that was apparently missing (x_rftractionmotor.wav​) from the locomotive. I eventually found and installed this missing sound file within the appropriate place and re-ran my activity. This time there were no further crashes, and the activity was successfully completed!

    I'm aware that in many cases of Open Rails and MSTS crashing, this is often due to sound files not being found. So installing the file x_rftractionmotor.wav seems to have solved the crashing issue.

    However! What is a bit puzzling is that I have another activity for NEC V4 that runs from Washington to Philadelphia. This activity uses seven DDA40X locomotives in a 3-2-2 configuration hauling a total of 144 coal cars. Now this activity was created and run well before I created the small seven coal car activity to Aberdeen, and well before I found I had to add the sound x_rftractionmotor.wav to the DDA40X locomotive.

    The puzzling part is that this larger activity with seven DDA40X locomotives and WITHOUT the sound file x_rftractionmotor.wav added, was completed successfully without any crashes!??

    With seven DDA40X locomotives (minus the sound file x_rftractionmotor.wav), I thought this larger activity would be far more likely to crash owing to Open Rails inability to find the file x_rftractionmotor.wav for all of the seven locomotives!?

    So why crashing only with one DDA40X locomotive on a short/simple activity and not crashing with seven DDA40X locomotives on the larger activity?

    Hi,
    In my experience, neither Open Rails nor MSTS will crash because of a missing .wav file. MSTS will only report an error, and maybe crash, if a .sms file is missing. For a missing .wav file, OR will only report it in its log. I suspect that, probably inadvertently, while adding the missing.wav file, you fixed the original problem

    Cheers,
    Ged

      Thanks for the comments.

      Using your excellent sms file checker software, it reported some missing sound wav's as well as a couple of either issues for both the cab.sms file and also for the associated eng.sms file.

      The sounds used for aliasing to the DDA40X are from this file mlw645turbo.zip. But according to sms checker report, the cab sound file sil.wav is missing (but should have been included with the sound set). At the moment I can't seem to find this file anywhere.

      Anyone know where to get this file?

      If I can't get this missing sound file, then I'll have to delete the entry within the associated cab.sms file so the simulation won't try to find this missing sound file.

      Presently editing the sms files as far as possible to correct the errors reported by sms checker.
