nstalling a sound decoder in a brass locomotive is not espe-
cially difficult for an experienced modeler, but it requires
some careful planning, familiarity with an ohmmeter, some
basic soldering skills and the ability to drill, cut and finish brass.
This article will assume you possess these skills plus the usual
modeler's hand tools, a decent ohmmeter and a soldering iron.
We will cover soldering small wires and components. The meth-
ods shown in this article are not the only way of doing them, but
they work and have been proven to be safe and reliable.
