When is a locomotive said to be
out of tram
? What are the bad effects of a locomotive being out of tram? What is the purpose of a proof line on a shoe or wedge? What two methods can be used for squaring the frame? How can the permanent centers be found if the trams cannot be passed over the top rails of the frame? How can a proof line on the frame be transferred to the shoes at the main pedestal? What is the proper method of marking off the wedges at the main pedestal?
If you can answer all these questions, maybe you don’t need this book. But if you’re of the growing number of live steam enthusiasts looking for information to help you design and build an engine, then you will love this book. And be sure to look for our two dozen other reproduced books from this ICS series on steam railroading as taught and practiced in the 1930s and 1940s.
