Some of the most important new technologies that contributed to late-nineteenth-century industrial growth were in the field

Important new technologies contributed to the nation' industrial growth in the field of transportation and rail roads, textile and manufacturing and invention of telegraph.

Explanation

Steam engines and its utilization in the filed of transportation of raw materials proved to be much faster and it paved way for speeding up the manufacturing process. steam engines were also used to drain out water from the oil and coal mines in America. Coal was used to power the engines and its availability was in plenty in North America.

Much parts of America were rich in exporting cotton and many textile shops were also set up in America. Sweatshops were also opened during industrialization. The invention of telegraph improved the speed of communicating from one place to another. It also became a status symbol in the american households.

the underground railroad (apocope of the metropolitan railroad) is a system of urban trains located within a city and its metropolitan area. it is characterized for being a massive transport of passengers in the big cities, uniting diverse zones and their environs, with high capacity and frequency and in segregated form to other systems of transport. metropolitan railroads are built underground or on the surface, although most systems use mixed models where sections are combined in both modalities.

1 - as a result, the metro tends to reduce car travel for two reasons: first, due to the greater transfer of users from the car and, second, due to the reduction in the acquisition of cars in homes located in sectors near the stations of the metro.

2 -the metro allows to contribute effectively to the achievement of all the objectives of an urban development policy: it improves the efficiency of the city's economy by reducing travel costs and also generates a higher level of activities in the city center, taking advantage of of the agglomeration economies.

3 -it is a clean means of transport, since it uses renewable energy (usually electricity), taking care of the environment and avoiding excessive pollution.
