I built a ceiling track for our living room in o scale. The problem is
-Its too loud! We can't even stay in the same room with it. No matter
what I try its too loud to stay on for more than a minute or so.
I was thinking about going over to a g scale battery operated train,
but use powered track in case I wanted to use a track powered one at a
later point. Would this work and will any battery powered train run on
any g scale track? Or should I just go over to plastic track entirely?
Or are the track powered trains quiet enough to leave running without
driving everyone crazy?
Is that Icelandic or K. Jones? Anyway, I presume you have built
you lay the track right on them? Try putting some sound-deadening
cork or Homasote or Celotex in between the track and shelves. That
Thanks for the memory jog! That sentence brought back a very old
and pleasant one.
In 1954, when I was about 8, we lived in Glen Ellyn, IL, just
outside of Chicago. One Saturday afternoon my dad took to to a
diner in nearby Wheaton, IL that had a wonderful (at least in my
opinion) way of delivering food. The counter was U-shaped, with
the ends against the wall to the kitchen. There was a O-guage
track along the back edge of the counter that emerged from/exited
to the kitchen through the wall. When an order was ready, it came
out via train, the plate riding on a flat-car. The train would
stop right in front of your seat.

Yes, but make sure it has insulated wheels, so the wheel sets don't
bridge the track electrically (causing a short.)
You've discovered why this style of layout isn't as popular as its
"practicality" would make you think.
Changing scale won't make much difference, since the shelving acts as
drumhead, amplifying the sound. To reduce the effect, you need both
sound dampening materials and additional mass in the substructure itself.
For sound dampening, isolate the track from the substructure as much as
possible. Do _not_ use nails, screws, or other track fastenings - these
transmit the sound to the shelving.
To increase mass, use 3/4" plywood, and a frame work of dimensional
lumber (1x2, 1x3, 04 1x4, depending on span between supports). It may
help to fasten the shelving rigidly to the wall, which will in effect
add the wall's mass. It may also have the effect of creating a structure
with several mutually interfering resonant frequencies, which also
dampens sound. Use latex glue such as Liquid Nails (tm), not nails and
screws (except as temporary fastenings until the glue dries.)
It also helps to use an open framework instead of a solid shelf, and to
fasten (use screws) the track to a track board cut to width and
curvature, and mounted on risers which in turn are screwed to the cross
members. This eliminates large flat areas of plywood (the drum head),
and creates a structure with that doesn't resonate. However, you still
need the sandwich described below. And you need some sort of "scenery"
to make it look OK.
Best method (sofar) is a sandwich of plywood + Celotex or other sound
deadening material such as insulating styrofoam board + cork ballast
strip + track. Use water based latex adhesive to glue the layers
together, and use the same stuff to glue the track to the cork. You may
use pins or nails until the glue dries, but pull them out afterwards. If
the three-layer sandwich doesn't work, try a layer a of foam rubber as a
fourth layer underneath it all. For the track itself, use plastic-tie
flex track. All metal track is itself rather noisy.
You should also, of course, service the loco and cars so that they run
as quietly as possible. If your train is an older one with metal wheels,
it may help to replace the metal wheel with plastic ones.
