UPSC CDS-1 – 2016
The correct answer is 180 days in advance ticket booking facility for passengers.
The Railway Budget 2015-16, presented by Suresh Prabhu, focused on several key areas including improved passenger amenities, technology adoption, safety, infrastructure development, and sustainability. Online booking of disposable bed rolls was indeed proposed. The development of a Defence Travel System to eliminate warrants was a stated priority. Bio-toilets were a major push for environmental sustainability and hygiene. However, the budget proposed increasing the advance ticket booking period from 60 days to 120 days, not 180 days. Therefore, 180 days advance booking was not a thrust area mentioned in that budget.
Other thrust areas in the Railway Budget 2015-16 included improving cleanliness, developing station amenities, focusing on high-speed corridors, attracting investment, and emphasizing safety and security. The increase in advance booking period was a measure aimed at passenger convenience and better planning.
