Current versions of these codes and standards now agree that handrail is defined as either a circular cross section with an outside diameter of 1 + 1 ⁄ 4 inches (32 mm) minimum and 2 inches (51 mm) maximum or a non-circular cross section with a perimeter dimension of 4 inches (102 mm) minimum and 6 + 1 ⁄ 4 inches (159 mm) maximum and a ...
Composite lumber can be used if a support rail is used along with it. The support rail is used between the posts to lend strength to the system, both between the posts, and to the Top Rail. Cable to cable spacing: Spacing of the cables vertically is critical to minimize deflection of the cables. Most manufacturers recommended maximum vertical ...
These include simple rail adhesion, rack railways and cable inclines (including rail mounted water tanks to carry barges). To help with braking on the descent, a non-load-bearing "brake rail" located between the running rails can be used, similar to the rail used in the Fell system, e.g. by the Snaefell Mountain Railway on the Isle of Man.
For example, North America uses the reference rail as the line rail which is the east rail of tangent track running north and south, the north rail of tangent track running east and west, the outer rail (the rail that is further away from the center) on curves, or the outside rails in multiple track territory.

Measurement of track spacing from the rail head to rail head. By definition, the track spacing is given from centre to centre of a rail track. For an actual construction the distance is measured from the inside of a rail head to the matching one of the other track. As far as both tracks have the same gauge this is the same distance.
For a line with a maximum speed of 60 km/h (37 mph), buffer-and-chain couplers increase the minimum radius to around 150 m (164 yd; 492 ft). As narrow-gauge railways , tramways , and rapid transit systems normally do not interchange with mainline railways, instances of these types of railway in Europe often use bufferless central couplers and ...
Gooseneck: The vertical handrail that joins a sloped handrail to a higher handrail on the balcony or landing is a gooseneck. Rosette: Where the handrail ends in the wall and a half-newel is not used, it may be trimmed by a rosette. Easings: Wall handrails are mounted directly onto the wall with wall brackets. At the bottom of the stairs, such ...
373 km (232 mi) of track until closure of the national rail network in 1993. All lifted and scrapped. Nigeria: Nigerian Railway Corporation operates an isolated network of 3,505 kilometers (2,178 mi) 3 ft 6 in (1,067 mm) gauge single track lines. Norway: The gauge was first used by C A Pihl on the Hamar-Grundset Line, opened 23 June 1862. [24]
