And (I have tried on a single section of mainline, for testing) to assist with sound reduction, make use of the ballast to secure you track. Forego the use of screws
to secure your track sections. If placed properly, the ballast may be sufficient to
hold trackage in place. A minimum use of screws on curves should be sufficient on most layouts, none on straight sections, just using ballast to hold. Also, a bit more "prototypical" ?
Just a thought to try out and see whether it may suffice for your own purpose.
