The first version of Isambard Kingdom Brunel's 7 ft (2,134 mm) broad gauge system used rails laid on longitudinal sleepers whose rail gauge and elevation were pinned down by being tied to piles (conceptually akin to a pile bridge), but this arrangement was expensive and Brunel soon replaced it with what became the classic broad gauge track, in ...
A railway track (CwthE and UIC terminology) or railroad track (NAmE), also known as permanent way (CwthE) [1] or "P Way" (BrE [2] and Indian English), is the structure on a railway or railroad consisting of the rails, fasteners, sleepers (railroad ties in American English) and ballast (or slab track), plus the underlying subgrade.
When American railroad tracks extended to the point that they began to interconnect, it became clear that a single nationwide gauge would be beneficial. Where different gauges meet, there is a "break of gauge". To overcome that problem, special compromise cars were able to run 4 ft 10 in (1,473 mm) and standard gauge track. [18]
The first tracks in Austria and in the Netherlands had other gauges (1,000 mm or 3 ft 3 + 3 ⁄ 8 in in Austria for the Donau Moldau line and 1,945 mm or 6 ft 4 + 9 ⁄ 16 in in the Netherlands for the Hollandsche IJzeren Spoorweg-Maatschappij), but for interoperability reasons (the first rail service between Paris and Berlin began in 1849 ...
In 1886, the southern railroads agreed to coordinate changing gauge on all their tracks. 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 ...
Albany and Susquehanna Railroad, Erie Railroad until June 22, 1880, Delaware, Lackawanna and Western Railroad March–May 1876, Predominant gauge used by railroads along southern tier of New York State that connected to the pioneering Erie Railroad. Most lines converted to standard gauge 1876-1880, along with the Erie. 1,850 mm 6 ft 27 ⁄ 32 in
Steam locomotives of the Chicago and North Western Railway in the roundhouse at the Chicago, Illinois rail yards, 1942. The Timeline of U.S. Railway History depends upon the definition of a railway, as follows: A means of conveyance of passengers and goods on wheeled vehicles running on rails, also known as tracks.
Height of rail equaled width of foot for each ASCE tee-rail weight; and the profiles specified fixed proportion of weight in head, web and foot of 42%, 21% and 37%, respectively. ASCE 90 lb/yd (44.6 kg/m) profile was adequate; but heavier weights were less satisfactory.
