## What is the minimum radius for N scale trains?

around 11″

The current accepted minimum radius for N is now around 11″. 9 3/4″ radius track is still widely available and called for in many track plans but most modern equipment and long wheelbase steam will have trouble with it. For best appearance passenger and 89′ modern cars, 14″ minimum radius is reccomended.

**What is a good radius for N scale?**

N Scale locos (for the most part) are designed to operate on a 9 3/4″ radius, which will fit nicely on a 24″x48″ layout. While it is possible to use a smaller radius, it is not recommended without testing it first.

### What is the tightest N scale radius?

The tightest track curve Kato manufactures for their N scale Unitrack has an 8.5 inch radius. This means that it’s possible to fit an oval of Unitrack in a space as tight as 18 inches, or a double track in an area with a width of about 22 inches.

## How many 22 radius curves make a circle?

Each piece is 22.5 degrees, so you need 16 pieces of 22 inch radius to make a full circle.

**How do you find the radius of a train track?**

The radius of the curve is the square of the chord divided by 8 times the versine.

### How tight can a train turn?

List of selected minimum curve radii

Gauge | Radius | Location |
---|---|---|

1,435 mm ( 4 ft 81⁄2 in) | 125 m (410 ft 11⁄4 in) | North American rail network |

1,676 mm (5 ft 6 in) | 120 m (390 ft) | Bay Area Rapid Transit |

1,435 mm ( 4 ft 81⁄2 in) | 100 m (328 ft) | Batlow, New South Wales |

1,067 mm (3 ft 6 in) | 95 m (312 ft) | Newmarket, New Zealand |

**What is the minimum radius for OO gauge track?**

The general advice is that you don’t run engines on anything less than a second radius curve (438mm or 17.25 inches) in 00 gauge (double the measurement for 0 gauge and halve it for N gauge).

## What is the smallest radius for Ho track?

Length of Your Train

Modeling Scale | Minimum Radius |
---|---|

N Scale | 9 3/4 inches |

HO Scale | 15 to 22 inches |

HOn3 Scale | 15 inches (narrow gauge) |

S Scale | 20 to 30 inches |

**What is the width of O gauge track?**

Gauge refers to the distance between the inside edges of the load-bearing rails. Various sizes of track gauge exist around the world and the normal O gauge track represents the Standard gauge of 1,435 mm ( 4 ft 81⁄2 in). “O gauge” refers to tracks that are 1.25 in (31.75 mm) apart.
