The Complex & Climax Division of the Union Pacific RailroadBy Eric and Jan Haas, Lafayette, Co. p. 66"Track power and wiringWith only a few exceptions, the long-range plan we created backIn 1998 has guided virtually every other decision we have made And executed over the past six years. Knowing that we intended To run very long trains, with multiple lash-ups, on multiple mainlinesCreates problems unique to this scale of operation.For example, there are 96 pairs of multi-conductor wire running Throughout the railroad. Due to load requirements of operating fourTo six engines, with up to 80 to 100 cars on any given mainline,The vast majority is #12 and #14 gauge wire.The railroad is powered by three separate 20amp circuits driving Three pairs of 12v automobile battery chargers, each set wired in Series. Battery chargers are cheap, and instantly available for $25Bucks at any K-mart or Wal-mart. For non-electrically inclined, "series" means taking the black lead from one charger and hooking it to the red lead on the other. The result is either 18V or 24V output,with unlimited amps (50 plus). To these power sources  are hooked eight Aristo-craft Train Engineer radio control receivers, each governing a particular segment of the railroad." There RR5 mainlines, 2 branch, app. 1200'+, in Aug 2004 Ref: above magazine for total article.
