Layouts
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.
Another modeler, also from Australia, has been building single track modules using the standard modules. He has a blog called Adventures in N Scale Model Railways.
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.
