As the wagon can move within the rail gauge one adds 100 mm (3.9 in) and with a possible displacement of tracks over time one adds some 250 mm (9.8 in) as a security margin. This leads to a minimum centre-to-centre spacing of 3,500 mm (11 ft 6 in).
Definition and Characteristics. Broad gauge tracks are defined by their wider distance between the rails, which is typically greater than the standard gauge of 4 feet 8.5 inches (1,435 millimeters). The exact width of broad gauge tracks can vary depending on the country and specific railway system.

In North America and the United Kingdom, rail is graded in pounds per yard (usually shown as pound or lb ), so 130-pound rail would weigh 130 lb/yd (64 kg/m). The usual range is 115 to 141 lb/yd (57 to 70 kg/m). In Europe, rail is graded in kilograms per metre and the usual range is 40 to 60 kg/m (81 to 121 lb/yd).
Mar 8, 2024 · Modern day train operations are largely controlled by train dispatchers or control operators. A dispatcher directly controls all movements on a given piece of track, while a control operator typically handles movement on a smaller piece of trackage — operating under the direction of a dispatcher. Control operators can typically be found at ...
Apr 20, 2014 · UK measure track distance between the rails near each other (right rail of left track to left rail of right track). The following are the basic numbers, translating from ft between tracks to metres between track centres: 6 ft = 3.4 m between running track pairs. 10 ft = 4.6 m minimum between sidings.
May 10, 2023 · Here’s how railroads design grades and curves. Grades: uphill and down. In North America, gradient is expressed in terms of the number of feet of rise per 100 feet of horizontal distance. Two examples: if a track rises 1 foot over a distance of 100 feet, the gradient is said to be “1%;” a rise of 2 and-a-half feet would be a grade of “2 ...
