Afternoon Gang! Tinkering and tweaking continues and there are signs of improvement. While running a loco down the track, I found out that some extra noise is coming from little grains of ballast stuck in the frogs, the guard rails or adhering to the web of the rail. I am playing Sherlock Holmes to find out these spots and remove those grains. Noise is a general problem with the layout. I have not installed a cork roadbed for two reasons, number 1 being the fact, that narrow guage lines usually did not have high ballast beds, number 2 being the fact, that, with the glue we have available here, the cork gets hard and loses the sound deadenig properties. I have made that experience a number of times with previous layouts. I still want to battle the noise and this is my idea: If I mount two or three 1" thick pieces of MDF underneath the roadbed in each section (there are four to each segment), this should change the resonance frequency sufficient to dampen the noise a little. Will this work?
