Greetings

I hope I’m at the right place. I’m looking for decent realistic track sounds to use in my MSTS US routes in OpenRails. I bought a sound pack from Railwaves.com some years ago which I use on my UK and European routes, but I’m not sure that using it on the US routes would be so authentic.
Besides, (and I know it will sound strange), I am blind, and having the ability to use different sounds on different routes would increase the variety of the content I can enjoy.
Having said that, the sounds that come with the original MSTS US routes are rather dull, especially the external ones.
I really hope someone would be able to give me useful pointers.
Thanks very much.
All the best
