Why did improved transportation the nation's economy?

Improved transportation helped the nation's economy by facilitating the movement of raw materials and finished goods from one place to another.

Explanation:

With the advent of industrialisation, the facilities of transportation also improved rapidly owing to new innovations in the locomotive industry. Improved transportation made it convenient to fetch raw materials from distant places and move finished goods to the market.

This allowed the goods to be evenly distributed in the market and thus the economic output multiplied.
