What scale is On30?
American O scale
On30 uses the American O scale of 1⁄4 inch to the foot, (ratio 1:48) to operate trains on HO gauge (16.5 mm / 0.65 in) track.
How do you convert HO scale to N scale?
Take all of the HO measurements and multiply them by 0.545 (this is the ratio between HO and N). An 18 inch radius in HO will become a 9.81 in N. Take all of the HO measurements and multiply them by 0.75. An 18 inch radius in HO will become a 12 in N.
What is the difference between On30 and On3?
On3 track gauge is three quarters of an inch (because American O scale is a quarter inch to the foot.) On30 is the same scale but runs on HO gauge track which is approximately 5/8 of an inch so the On3 is about 1/8th inch wider.
How do you convert HO scales to inches?
This is scale feet. To get inches from this start with the first number 20. Take 20 times 12 (which is how many inches there is in a foot) 20 X 12 = 240. Take the 240 and divide by 87 (for HO Scale) and you get 2.758.
What is the difference between On30 scale and HO scale?
On30 is 1:48 scale, the same as O scale. It’s a subset of O scale. HO scale is 1:87 scale, about half the size. It turns out that HO scale track is about 30 inches wide in O scale, making it convenient for modeling narrow gauge trains.
What is HOn3 scale?
HOn3 Scale (1:87), otherwise known as HO Narrow Gauge, is a subcategory of HO scale trains. HOn3 trains are the same scale and size as HO scale trains, but they operate on different track. HOn3 trains run on track whose rails are more narrowly distanced from each other than rails on HO scale, or standard gauge, track.
How do you calculate HO scale?
HO scale is 1:87.1 ratio. If you have 36 HO scale inches, just divide it by 87.1 giving you .
How long is a foot in HO scale?
In North America, the National Model Railroad Association (NMRA) standard “S-1.2 General Standard Scales” defines HO scale as 3.5 mm (0.1378 in) representing 1 real foot (304.8 mm) – a ratio of 1:87.0857142, usually rounded to 1:87.1.
Is On30 the same as HO?
How tall is On30 scale train?
On30, sometimes also named On2½, is a narrow gauge railway for O-Scale. The Scale is 1/48 (1/4” to 1′). The On30 gauge is . 649” (16,5 mm), same as HO.
How long is a mile in HO scale?
03937 inches (1 mm). 0.03937 X 3.5 = 0.137795 inches in one HO scale foot. 5280 X 0.137795 = 727.5576 inches in one HO scale mile. 727.5576 divided by 12 = 60.6298 feet in one HO scale mile.
Is HOn3 the same as N scale?
Is there a difference in rail size between HOn3 and N scale? Yes, they are different, true HOn3 is slightly wider than N, however HOn30 is compatible with N (the difference being HOn3 is Scale 36 inch [3 foot], as HOn30, is 30 inch).
