In the years before World War II, Lionel was the leader in the U.S. in manufacturing of model railroad equipment, specialising in “tinplate” models which were often unrealistic in scale, painted in garish colours, and appealing to young children and the mothers who bought them as gifts. During the war, the company turned to production of items for the U.S. Navy. After the war, the company returned to the model railroad market, remaking their product line with more realistic models. This coincided with the arrival of the baby boom generation, which, as the boys grew up, had an unlimited appetite for ever more complicated and realistic model railroads, which Lionel was eager to meet with simple, rugged, and affordable gear which set the standard for model railroading for a generation.
This book, published in 1951, just as Lionel was reaching the peak of its success, was written by Raymond F. Yates, author of earlier classics such as A Boy and a Battery and A Boy and a Motor, which were perennially wait-listed at the public library when I was a kid during the 1950s. The book starts with the basics of electricity, then moves on to a totally Lionel-based view of the model railroading hobby. There are numerous do-it-yourself projects, ranging from building simple scenery to complex remote-controlled projects with both mechanical and electrical actuation. There is even a section on replacing the unsightly centre third rail of Lionel O-gauge track with a subtle third rail located to the side of the track which the author notes “should be undertaken only if you are prepared to do a lot of work and if you know how to use a soldering iron.” Imagine what this requires for transmitting current across switches and crossovers! Although I read this book, back in the day, I’m glad I never went that deeply down the rabbit hole.
I learned a few things here I never stumbled across while running my Lionel oval layout during the Eisenhower administration or in engineering school many years later. For example: why did Lionel opt for AC power and a three rail system rather than the obvious approach of DC motors and two rails, which makes it easier, for example, to reverse trains and looks more like the real thing? The answer is that a three rail system with AC power is symmetrical, and allows all kinds of complicated geometries in layouts without worrying about cross-polarity connections on junctions. AC power allows using inexpensive transformers to run the layout from mains power without rectifiers which, in the 1950s, would have meant messy and inefficient selenium stacks prone to blowing up into toxic garlic-smelling fumes if mistreated. But many of the Lionel remote control gizmos, such as the knuckle couplers, switches, semaphore signals, and that eternal favourite, the giraffe car, used solenoids as actuators. How could that work with AC power? Well, think about it—if you have a soft iron plunger within the coil, but not at its centre, when current is applied to the coil, the induced magnetic field will pull it into the centre of the coil. This force is independent of the direction of the current. So an alternating current will create a varying magnetic field which, averaged over the mechanical inertia of the plunger, will still pull it in as long as the solenoid is energised. In practice, running a solenoid on AC may result in a hum, buzz, or chatter, which can be avoided by including a shading coil, in which an induced current creates a magnetic field 90° out of phase to the alternating current in the main coil and smooths the magnetic field actuating the plunger. I never knew that; did you?
This is a book for boys. There is only a hint of the fanaticism to which the hobby of model railroading can be taken. We catch a whiff of it in the chapter about running the railroad on a published schedule, with telegraph connections between dispatchers and clocks modified to keep “scale time”. All in all, it was great fun then, and great fun to recall now. To see how far off the deep end O-gauge model railroading has gone since 1951, check out the Lionel Trains 2019 Catalogue.
This book is out of print, but used copies are readily available at a reasonable price.
