Track gauge conversion is the changing of one railway track gauge (the distance between the running rails) to another. In general, requirements depend on whether the conversion is from a wider gauge to a narrower gauge or vice versa, on how the rail vehicles can be modified to accommodate a track gauge conversion, and on whether the gauge conversion is manual or automated.
The San Francisco cable car system is the last manually-operated cable car system in the world.. A list of 3 ft 6 in (1,067 mm) gauge railways in the United States.Apart from historical railways, it is commonly used in underground coal mines.
This is a list of 3 ft (914 mm) narrow-gauge railways in the United States. Narrow-gauge railroads of various sizes existed across the US, especially during the late 1800s, with the most popular gauge being 3 ft gauge. [1] [2] Some of the more famous 3 ft gauge railroad networks in the US were based in California, Colorado, and Hawaii. These ...
A Talgo train with a locomotive can drive across a gauge change at 1 axle per second at a speed of about 10–15 km/h (6.2–9.3 mph). [35] [36] A train (or an individual car) can be pushed halfway across the gauge-changer, uncoupled, and then (once far enough across) coupled to the new locomotive and pulled the rest of the way.
The new gauge was close enough that standard gauge equipment could run on it without problem. By June 1886, all major railroads in North America, an estimated 11,500 miles (18,500 km), were using approximately the same gauge. To facilitate the change, the inside spikes had been hammered into place at the new gauge in advance of the change.
After considerable debate and planning, most of the southern rail network was converted from 5 ft (1,524 mm) gauge to 4 ft 9 in (1,448 mm) gauge, then the standard of the Pennsylvania Railroad, over two days beginning on May 31, 1886. Over a period of 36 hours, tens of thousands of workers pulled the spikes from the west rail of all the broad ...
Thus the scale and approximate prototype gauge are represented, with the model gauge used (9 mm for H0e gauge; 6.5 mm for H0f gauge) being implied. [2] The scales used include the general European modelling range of Z, N, TT, H0, 0 and also the large model engineering gauges of I to X, including 3 + 1 ⁄ 2, 5, 7 + 1 ⁄ 4 and 10 + 1 ⁄ 4-inch ...
Change of gauge or gauge change may also refer to: Change of gauge (aviation), change of aircraft without changing the flight number; Break-of-gauge a location where two railroad lines of different gauge meet; Bogie exchange, a system for operating railway wagons on two or more gauges by switching bogies; Variable gauge, a system using ...
