Jim Weatherford, CTT’s former Q&A columnist, offers an extensive line of how-to repair articles for postwar Lionel trains. Available are a series of articles in four general categories: locomotives, tenders, accessories, and operating cars. Each article contains detailed instructions, close-up images, tool lists, and testing and re-assembly instructions. Articles are on a CD and are in an e-book format (reader software is included). Mac users need to use a PC emulation program. Prices vary by complexity: a repair article for the no. 736 Berkshire costs $14.75 and a repair article for the no. 3469 coal dump car costs $7.95. Shipping to the continental U.S. costs $2. For the complete list and more, go to jwtrains.com ."
