Early tracks were constructed with wooden or cast iron rails, and wooden or stone sleepers; since the 1870s, rails have almost universally been made from steel.

(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.
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.
By 1850, more than 9,000 miles of railroad were in operation. In these early years, railroads provided a means for previously inaccessible areas to be developed; for mineral, timber and agricultural products to get to market; and for the developed and undeveloped areas of a growing nation to be bound together.
Because friction is the enemy of rail transportation, a key engineering principle is to keep grades low and curves to a minimum. As a result, the best routes across the continent often followed the natural courses of water.
First of all, steel rails are exposed to the air for many years. In the long days of wind and sun, there will inevitably be rusting, but during the use, the train will pass through rails, and rust will rub on the wheels.The part is worn off.
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.
Wood has the natural flexibility that is perfectly suited for the loads running on railroad tracks every day. Wood ties are engineered to perform under heavy load conditions. The durability of the wood tie means lower costs for railroads.
Walking on or beside railroad tracks is illegal. The only safe place to cross tracks is at designated public crossings with a crossbuck, flashing red lights or a gate. Crossing anywhere else is illegal.
A crossover is a pair of switches that connects two parallel rail tracks, allowing a train on one track to cross over to the other. Like the switches themselves, crossovers can be described as either facing or trailing.
When properly maintained by a Midwest railroad contractor, a modern running track has the potential to last for almost 30 years after its construction. It may be difficult to recognize the signs of deterioration in rails because they appear to last an entire lifetime.
Misguided railroad regulation was a major factor behind the rail industry's decline. For example, the ICC set maximum and minimum rates for rail shipments, with rates often unrelated to costs or demand.
