Benefits for railways and officers having a single time zone in big country like India

Explanation:

• One of the benefits for railways and officer with India having a single time zone is that it prevents the risks of accidents. If there is more than one time zone for India, there is the risk of railway accidents as there would be a requirement  to reset times at each crossing from one time zone to another.  
• India has an immense population; it would be chaos at the border between the two regions the country was split in two time zones. That would mean the clocks will be reset for each time zone crossing.
• More serious confusion can be experienced. Rail signals in our nation are not fully automated and there are several routes on one track. Because of human errors trains can suffer major accidents. Just one such incident will negate any gain resulting from the country's different time zones.
