Indian Railways (IR), with over 68,031 route kms, is the fourth largest network in the world. Hence, statement 1 is correct. The fast pace of infrastructure augmentation by IR has been a result of substantial increase in allocation of funds and various steps being taken by the government. The capital expenditure (Capex) on infrastructure in railways has received a tremendous boost since 2014. It has seen a continuous increase in the last four years with Capex of Rs. 2.5 lakh crore in FY23, up by around 29% compared to the previous year. Hence, statement 2 is not correct and 3 is correct.
