Rail weights up to 90# per yard and with standard old lengths of 33-39 feet can be bent simply by spiking one end and slowly working in the other end to gauge. This works on curves as sharp as 16-18 degrees with this weight rail.

Rail is not even very stiff in short lengths unless it is quite heavy. Rail weights up to 90# per yard and with standard old lengths of 33-39 feet can be bent simply by spiking one end and slowly working in the other end to gauge. This works on curves as sharp as 16-18 degrees with this weight rail.
(2) Your rail that had to be bent could be bent by using heat/fire and track jacks. (3) As is true today, most sharp curves were found off in the yards, backtracks or on narrow gauge allignments.
Generally laid perpendicular to the rails, ties transfer loads to the track ballast and subgrade, hold the rails upright and keep them spaced to the correct gauge. Wooden ties are used on many traditional railways.
If a railroad wants to design curves with the ability to take all kinds of cars and locomotives, you won't see curves much tighter than about 14 degrees. If the railroad is willing to restrict some types of cars, like autoracks, then 18 or 20 degrees will be the maximum.
Locomotives and tracks began to wear out. By 1863 a quarter of the South's locomotives needed repairs and the speed of train travel in the South had dropped to only 10 miles an hour (from 25 miles an hour in 1861). Fuel was a problem as well. Southern locomotives were fueled by wood--a great deal of it.
The author was just one of the thousands of people who flocked to the Transcontinental Railroad beginning in 1869. The railroad, which stretched nearly 2,000 miles between Iowa, Nebraska and California, reduced travel time across the West from about six months by wagon or 25 days by stagecoach to just four days.
A small gap is left between two subsequent rails while installing. The rails expand on account of thermal expansion due to increased temperature in summer. If no spacing is left, the rails can bend sideways due to expansion in summer, leading to train accidents.
The steepest adhesion railroad grade in the USA is found at the Cass Scenic Railroad in West Virginia. Shay geared steam locomotives haul tourist trains up a maximum grade of 11% on this former logging railroad.
The Madison Incline is the steepest line-haul, standard gauge railroad track in North America. Opened in 1841, the incline has been in existence for nearly 180 years. At 5.89%, this incredible feat of engineering proved to be a challenge for its operators and was last used in 1992.
