DCForum Discussion Forum - Need advise on sounds and Marias Pass 3

I downloaded the TSlogodash9 into the Sim and when I used the Sim I lost the outside the locomotive brake sounds and also the train crossing bell sounds.
I had to re-install to get these back.
What is happening when I add this to the Sim and use it in this route?
It is also interesting that my activity starts on the west side of the viaduct in Whitefish and those sounds are in the Sim until I go under the viaduct and when I am on the depot side they do not work anymore.
That seems odd to me.
Can any help and shed some light on this?
Thanks.
