Everything the Britishers did in India had a military objective. Take the case of railways.Broad gauge lines connected the cantonments for large scale military movements. The princely states of India could have only narrow gauge lines to prevent them from large scale movements. Thus we have a narrow gauge line in Mayurbhanj. The mutiny centres were connected too.Sambalpur was not a cantonment town, but it was a centre of mutiny.Hence merited a branch line from the Calcutta-Bombay trunk route. When a broad gauge line had to pass through a native state, a British and later an Anglo Indian station master was appointed.
