Bus Wiring For Model Railroads
Model railroad track supports and supplies the power to electric trains. But tracks have joints and these gaps are barriers to the electric current. A single rail joint, securely anchored with a joiner, will not cause a noticeable voltage drop. Multiplied over an entire layout, the cumulative voltage drop can cause your train to slow down or stall as it gets further from the power supply. If gaps are larger or rail joiners loose, the problem increases....
