Thank you to one and all - your comments ad ideas will be taken onboard. I would like to add specific comments to the various responders:
Brendan: Yes I have a heap of spare track and I will try ballasting a couple of sections to see what it looks like. Both sections of your track in the photos look amazing. Thank you.
Mike Wyatt: You have nailed it so succinctly!!!! Yes I am "TOY TRAIN" type of guy, but also like the more modern locos produced by MTH. I have just recently purchased a brand new BNSF Dash 9 diesel with all of the "railsounds" and love running it on my "Swiss" track using my Lionel RS-1 transformer.
Vistadomescott: I have included a photo of the "baby" that is parked in the wife's garage, just for you.
GFTIV: Adding extra ties (we call them "sleepers" here in Australia) is possible however the track is becoming a "collectors item" now, as the Buco company went bankrupt back in 1957. Original Buco stamped track is getting a little scarce, and I really don't want to alter its appearance if I can help it.
Moonson: You certainly posses "words of wisdom" that I value in relation to my kunundrum. The Buco track is becoming too expensive and too rare to damage or lose it, if a track re-design was ever contemplated. I might take your suggestion and just loose lay some ballast on one section of the main line and see how it performs. I have heard (on this forum) that "loose" ballast can get into the drive gears of the loco's and cause damage.......that is the last thing I would want to happen.
Arnold: The photos of your track also look great. The ballast I have is more like the "chick grit" described by others.
D500: The "Group A" engine has Chevy Corvette "brown" double valve springs as standard, and "Directional" alloy wheels based on the Corvette. I have included a photo of my "baby" with the directional wheels. I love your Dodge Challenger R/T - nearly got one in Miami, Florida 2yrs ago when we were driving across America, and our Alamo rental car (Kia Cerato) died on us. The wife said we couldn't afford the petrol (gas) to run it all the way back to Los Angles - I still think she was wrong!!!!
Mark: I also have a "bundle" of new GarGrave track I bought from the States some years ago when I couldn't get anymore Buco 3 rail track and intended using it on the back straights where it would not be as noticeable. As it turned out, I got onto an auction site in Switzerland (Ricardo) and was able to purchase enough spare track to complete my layout and to fill a couple of plastic storage containers as well. Thank you also for your comment on my layout and I will do a "test section" to see what it looks like.
William 1: I have attached a couple of photos of the layout with the sound insulating anti slip underlay in place and the track relayed. Hope you like them. PS. I ran a couple of my Buco locos around the layout last night to test it for electrical continuity and the reduction in noise was incredible....the loco's (both running at the same time chasing each other) were whisper quiet. I am stoked!!!!!
Thank you one and all.......Peter (Buco tragic) on the Gold Coast, Queensland, Australia
