Railways:
- The railways played a crucial role in the economic development of the colonial countries. They were considered a strategic asset and were often owned and operated by the government.
- The colonial governments saw the railways as a means to facilitate trade and transportation, connect different regions, and promote industrialization.
- Governments invested significant resources in the construction and maintenance of railways, and they were often the largest employer in the country.
- Railways were also used for military purposes, enabling the transportation of troops and supplies across different regions.
- The government-owned railways were responsible for setting fares, schedules, and maintaining the infrastructure. They were seen as a public service and were expected to provide reliable and affordable transportation for the general public.

Other Industries:
- While railways were a prominent industry under the public sector during the colonial period, other industries such as animation and IT did not exist or were not significant during that time.
- Animation, as we know it today, emerged much later with the advent of computers and advanced technology.
- Similarly, the IT industry was not present during the colonial period as computers and advanced telecommunications were not yet developed.
