Russ, your comments about the layout are all so very true. But I started this thread to discuss and may be to understand the causes of noise prevention other than the layout. Even with my for from ideal layout is the noise produced by different engines of different brands remarkable. We all know the two prominent sources in the engine are the motor and the gear. But I noticed there are some engines that hit the drum much less than others.
A good example are Atlas GP38 vs. Athearn RTR CF7 WITH a perfect running Kato motor.
Running on perfect track (rubber cushion) are both engines very quit. But on the layout runs the CF7 like on a drum while the GP38 runs like on rubber tires. You will fine in the posting from " by Sumpter250 on 09 Feb 2012, 19:59" a possible solution how the truck design make engines run different on the same kind of roadbed.
