Thanks for those, but those aren't good. I think the MFSE old version was probably quietest...it had BALAST.Would you happen to know why the old version was replaced? Concrete ties are also LOUDER than wood ties. . . None of the examples I showed employed concrete ties. . . .and rails laid in concrete are loud, even with the rubber. In my experience the sound from the propulsion system and the HVAC make more noise then the noise coming from the wheels rolling on the rails. John in the sand box of Maryland's eastern shore. |
