AWG Conversion Table

N Gauge Model Scale
| N Gauge Summary | |||
|---|---|---|---|
| Region | Scale Ratio | Track Gauge | mm per ft |
| British | 1:148 | 9 mm | 2.06 |
| European & USA | 1:160 | 9 mm | 1.9 |
| Japanese | 1:150 | 9 mm | 2.03 |
Model Weight
National Model Railroad Association Recommended Practice RP-20.1 - Car Weight 0.5 ounce weight plus .15 ounce per 1inch of truck
| Conversion Table |
|---|
| 1.0 oz = 28.3495 g |
| 0.5 oz = 14.175 g |
| 0.15 oz = 4.25 g |
Model Voltage
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)
Model Lengths
Approximate length of my trains I use to calculate block and station lengths.
| Train | Length |
|---|---|
| 1 coach | 16cm |
| 2 coaches | 32cm |
| 3 coaches | 48cm |
| 4 coaches | 64cm (about 25in) |
| 5 coaches | 80cm |
| 6 coaches | 96cm (about 38in) |
DCC Termination
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.
