Tips, techniques and commentary from Master Model Railroader Tom Piccirillo
Wiring and electronics of a model railroad layout require a few basic skills and tools.
In recent years, the most-exciting model railroad innovation has been in the field of electronic control. Micro-size components allow the installation of incredibly sophisticated circuits inside small-scale locomotives. These circuits not only allow individual control of trains on the same track, but also provide realistic sounds that emanate right from the locomotive itself. The resulting realism creates a whole new dimension to model railroading.
