This the book I was re-reading this weekend to brush up before starting in on the diamond crossing for Comstock Road. I have had this book for many years and actually did a search of my previous postings because it seemed strange that I had not already done a post on this book.
This classic is THE book for those intending to hand lay model railroad track in the North American tradition. It covers all kinds of details of the prototype and then gets down to practical advice for the modeller. Written long before DCC or the advent of the Fast Tracks CNC made jig empire, the methods described are what you need to build any kind of track using flat bottomed rail, spikes and a few simple tools. I needed to re-read parts of it because I haven’t built a turnout frog from scratch in more years than I care to count but the asymmetrical diamond on Comstock Road is just the sort of situation where these methods shine.
Even if you do everything with commercial jigs or castings, I highly recommend this book as a reference for prototype practice and other practical trackwork matters. Published by Carstens, it is currently out of print and not listed on the White River Productions site although several other Carstens books are. It looks like the book stand at train shows is your best bet if you want a copy although you might turn up a reasonably priced copy online. (unlike the unreasonably priced ones I found when I checked while writing this post.)
