Ian Morton, well known for his modelling knowledge through his contributions to the popular Aspects of Modelling series, provides the definitive guide to digital command control, which is the most significant recent advance in model railway technology. The advent of DCC has allowed the enthusiast to control more than one train at a time via the use of computer chip technology. Whereas most modern rolling stock is now designed to be fully compatible with DCC, for modellers it may represent a challenge - particularly if they have collections of locomotives and rolling stock that pre-date its development. This informative volume includes step-by-step photographs showing how all model locomotives can be converted to DCC operation. Other areas covered include: * The history of DCC; * The process of converting an existing layout to DCC or installing DCC on a new layout; * The advantages and disadvantages of conventional control systems and DCC, from the perspective of British model railway practices; * Decoders and the choice of unit for specific locomotives, providing step-by-step instructions. * Fitting of DCC-controlled sound modules * Lighting coaching and multiple-unit stock This definitive guide contains instructive text aligned to a wealth of images, making it a must for rail and modelling enthusiasts worldwide.
