What if a loco carried its own power on board? It would enter
the realm of battery-powered model railroading. This article
is an exploration of battery power for HO scale modeling,
from relatively simple to more complex applications. Different
approaches are presented with successful results and prob-
lems encountered along the way.
Battery-powered scale models exhaust all their power.
Constantly replacing them can be both expensive and prone
to damage in small scales. One then considers rechargeable
