|N Gauge Summary|
|Region||Scale Ratio||Track Gauge||mm per ft|
|European & USA||1:160||9 mm||1.9|
National Model Railroad Association Recommended Practice RP-20.1 - Car Weight 0.5 ounce weight plus .15 ounce per 1inch of truck
|1.0 oz = 28.3495 g|
|0.5 oz = 14.175 g|
|0.15 oz = 4.25 g|
Track Voltage - 12 volts typical - see Electrical S-9-1 Electrical Standards for Digital Command Control (PDF)
Lenz suggest 14 volts due to wire and electronics voltage drop. I will test on my Lenz LV101 LV102 and LV103 (to confirm actual settings)
Approximate length of my trains I use to calculate block and station lengths.
|4 coaches||64cm (about 25in)|
|6 coaches||96cm (about 38in)|
It has been suggested that DCC line should be terminated with a filter made of 150R resistor and a 0.1uF capacitor (or 1k and 0.01uF) in series across the ends. For scales HO and N, a half watt resistor is the minimum. The capacitor should be at least 50v DC.
I have not tried this and so can not comment on it's viability.
