SCALES



Each offers a size for your needs or space availability to develop the hobby, the most popular scales are "HO" and "N" because you can develop in a short space lying at a reasonable price.
In the photo at right shows an example of five scales, beginning from above we have:

I = 1:32 O = 1:43 HO = 1:87 TT = 1:120 N = 1:160

scales such as the "O" or the "1" are perfect to be able to develop Outdoor hobby, ie you can assemble cables in the garden of your home.

As you can see several scales from which you have:

WEIGHT OF ROLLING STOCK

Freight Cars
To calculate the freight cars using the following formula: a basic weight of 30 grams. and adds 15grs. for each 25mm long

LENGTH (feet) PROTOTYPE HO LENGTH (MM) WEIGHT Grs.
24 Miners 89 85
36 Tanks and Hoopers 127 106
40 Steam load time 140 114
50 Standard length 1950 178 136
60 Modern flats 216 160
85 Beaches 305 215



PASSENGER CARS
To calculate passenger cars using the following formula: a basic weight of 50 grams. and adds 15grs. for each 25mm long

LENGTH (feet) PROTOTYPE HO LENGTH (MM) WEIGHT Grs.
30 Short Service 105 115
36 First time 127 126
40 Early 1900 140 134
48 First Harriman (wood) 167 150
50 Standard since 1930 178 157
60 Standard since 1950 216 180
65 Metal with rivets 226 186
75 Straline 260 206
85 Supercine 295 230



For locomotives the calculation is made on the basis of 250grs. but the addition of 25 grams. per 25 mm. It is clear that the final weight can vary by model and time of construction.
The weight should be evenly distributed throughout the machine in the case of diesel or electric, in the case of steamers weight should be concentrated on the section containing the tractive (boiler or tender) in a ratio of 65% ( power) to 35% (Dumi) as.
