The Micro/Small
Layouts 
for model railroads is home to the Small Layout
Scrapbook. It is full of pictures and ideas from small layouts
around the world. Another section at the same site has a set of
instructions
to build
your own
turntable from a CD, and has
a N
shelf
layout using a similar turntable.
For T-Trak information start with
the Official
T-Trak site and then continue on with
the Unofficial
TTrak Handbook . Finally
the Australian
T-Trak group has a good guidelines document.
The Northern Virginia
NTRAK club has
a T-Trak
division with a gallery of their modules. For more examples visit
the Roseville
Roundhouse MRR
Club and look at their
modules. These t-trak
modules have great examples of sky boards that are something
other than plain blue
The T-Trak Yahoo group has a collection of photo albums. I like the one by Rob from Australia with the two different stations.
These sites feature N scale trains and paper model kits from
scalescenes.com. The first is a
small show display
layout . The second
is Ardley
Bridge as seen in a gallery of photos featuring it and a variety
of other model railroad projects.
This
site, Papphausen , has a lot of interesting pictures and information
gathered from the author's many model railroad layouts. He also has
a great section
on scratch-building using paper and cardboard.
This waterfront
layout by Kaustav has some very interesting examples of scratch-building,
from oil storage tanks to cranes to ships.
Another spin on the T-Trak standard comes in the form of these amazing Japanese modules that use a single track instead of double. Also the Japan Rail Modelers of Washington DC have an article about building these mini-modules.
