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.

While the US was a passenger train pioneer in the 19th century, after WWII, railways began to decline. The auto industry was booming, and Americans bought cars and houses in suburbs without rail connections. Highways (as well as aviation) became the focus of infrastructure spending, at the expense of rail.
The conversion from wood to coal began in Vermont around 1880 and was complete by 1892, with the bulk of the conversions taking place between 1884 and 1886. Coal was carried in a car behind the engine, and coal plants were constructed along rail lines. By 1890, passenger trains were equipped with steam heat.
Railroad ballast is a crucial component of the rail transportation system. It is a crushed stone or gravel material that is used to support and level the tracks in a railroad track bed. The primary purpose of ballast is to provide stability to the tracks, allowing trains to run smoothly and safely.
Do trains drop waste on the tracks? Not anymore. In the US until the 1960's, some toilets emptied directly onto the tracks. A sign was posted over the toilet reminding passengers not to flush while the train was on the station.
We paint certain parts of the rail white so they absorb less heat – and expand less. Typically, a rail painted white is 5°C to 10°C cooler than one left unpainted.
Property rights. One of the most expensive parts of building new rail lines these days is securing land along a relatively straight path (you can't run trains at high speeds along too sharp a curve). The U.S. has strong property rights which makes securing land exceedingly expensive.
CLIMATEWIRE | The first U.S.-made high-speed bullet trains will start running as early as 2024 between Boston, New York and Washington, with the promise of cutting transportation emissions by attracting new rail passengers who now drive or fly.
Railway tracks are laid on large sized wooden sleepers so , that the thrust due to the weight of train is spread over large area . This reduces the pressure on the ground.
Passenger cars have increased greatly in size from their earliest versions, with modern bi-level passenger cars capable of carrying over 100 passengers.
