The spelling word that refers to a framework built to carry railroad tracks is "viaduct." A viaduct is a long bridge-like structure that spans over obstacles, such as valleys or roads, allowing trains to travel smoothly along elevated tracks.

Railroad tracks that were built in the early 1900s were constructed from steel. The steel was used to replace rail tracks and railway cars that were built from iron prior to the early 1900s.
Inside mines. Long before railroads were built.
The tracks have a larger coefficient of linear expansion than the ground beneath.
That's a railroad
The Central Pacific Railroad (CPRR) was a transportation means built from California to Utah between 1863 and 1869. The CPRR was the western part of North America's First Transcontinental Railroad. The CPRR's tracks met with Union Pacific tracks in Promontory, northern Utah, on May 10, 1869.
Andrew Carnegie worked for the Pennsylvania Railroad. He continually created products they needed to solve those problems and made the companies to produce them. Eventually he owned a number of different companies producing a variety of products. He took a trip back to his home in Scotland. In England he saw the Bessemer Converter producing steel. He realized that steel railroad tracks would be far superior to iron tracks. He returned to the United States and sold all his companies and built a steel mill using the Bessemer Converter. He sold railroad tracks. Other companies in the United States had built Bessemer Converters before he did. He was the first to use the steel for railroad tracks. Since iron tracks wore out in few years, there was tremendous demand for Carnegie railroad tracks. He not only build the factory but also saw where its products were needed.
Railroad tracks were constructed by various groups throughout history, including laborers, engineers, and companies involved in the railroad industry. In the United States, significant contributions came from immigrant workers, particularly Irish and Chinese laborers, who built many of the transcontinental railroads in the 19th century. The tracks were designed and overseen by engineers and railroad companies, with major players like the Union Pacific and Central Pacific Railroad leading the construction efforts.
Since the 1870's railroad tracks have been built almost exactly the same. The tie is the wooden beam the keeps the rail (steel usually) off the ground, the rail is connected to the tie with two spikes on either side, and gravel as the base.
In New York, railroad tracks were primarily built in and around New York City, connecting various boroughs and facilitating transportation across the region. Key areas included Manhattan, where the elevated railroads and the underground subway system were developed, as well as the Bronx and Brooklyn. Additionally, major rail lines like the Erie Railroad and the New York Central Railroad extended into upstate New York, linking urban centers with rural areas. These tracks played a crucial role in shaping the state's economy and urban development.
