Build a 7 ½ Gauge Railroad in your Backyard: T-Rail and Groovy Track by Laurence Johnson. Here is an interesting read of Mr. Johnson’s experiences building his 7 ½ gauge railroad setup in his back yard. He includes the how-to in collecting supplies and has diagrams and lots of information with detailed drawings of assembly and getting it all together. Building a backyard train takes time and can take on a life of its own, and Laurence calls his experience a “learning curve”. Lots of interesting commentary to enjoy while you’re improving your own ”learning curve.” Softbound. 116 pages.
