Forms of transportation in the system
In the New York Rapid Transit System there has been many different ways to get around, and as time went on, these ways progressively got better. The transport started in humble beginnings with a simple horse and buggy going up and down a road. Later, when electricity was big, the horses were replaced with electronic trolleys. More and more ways were added to the system, like bridges above the streets, which had trains going along them with cables that pulled them back and forth. Buses eventually became normal on the roads with the system, buses are common in cities all over the United States. The fist demonstration of thye underground subway was debut in 1869 by Alfred Ely Beach. The subway was finished in 1904 by the IRT, the railroad was added onto and built by both the BRT and the IRT. ways of building the subway in the early 1900s was by digging up the ground, putting in the tracks, and then rebuilding the ground above it with enough room to have a train go through, but as they had to dig deeper, mining shields were needed to dig. About 40% of the system runs above ground on elevated steal cast or iron elevated structures, concrete viaducts, embankments, open cuts, and surface routes. All of these methods are completely grade-separated from road and pedestrian crossings, and crossings of two subway strips are grade-separated with flying-junctions.
