The Overseas Highway was built to connect the Florida Keys to the mainland of Florida, providing a vital transportation link between the islands and the rest of the state. It was constructed to replace the Overseas Railroad, which was destroyed in a hurricane in 1935. This new road allowed for easier access to the Keys for residents, tourists, and businesses.
The first such railroad tunnel, constructed for the Allegheny Portage Railroad in Pennsylvania, was completed in 1832

The Baltimore & Ohio Railroad (B&O).
They found tons of land to lay the railroad. If I remember my history, one railroad had been constructed through a wetern town named Rock Ridge, only because quicksand was found where the original track was to be laid.
They are called "railroad apartments."
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.
The first railroad charter was granted to John Stevens in North America in 1815. The first transcontinental railroad was a 1907 mile contiguous railroad line. It was constructed between 1863 and 1869.
The transcontinental railroad in the United States first started in the west at Sacramento, California. It was constructed by the Central Pacific Railroad, which began laying tracks eastward from Sacramento in 1863. The railroad was completed on May 10, 1869, when it joined with the Union Pacific Railroad at Promontory Summit, Utah. This monumental achievement connected the eastern and western parts of the country, facilitating commerce and travel.
The first transcontinental railroad in the United States was constructed by the Central Pacific Railroad and the Union Pacific Railroad. The Central Pacific started building eastward from Sacramento, California, while the Union Pacific built westward from Omaha, Nebraska. The two lines met at Promontory Summit, Utah, on May 10, 1869, marking a significant milestone in American transportation and expansion.
They could be built almost anywhere.
