Q. In how many Uttarakhand districts are railway tracks laid?
Answer: 4
Notes: Railway lines in Uttarakhand exist mainly in Dehradun, Haridwar, Udham Singh Nagar, and Nainital districts. Hill districts like Chamoli, Pauri Garhwal, and Uttarkashi lack operational railway lines. New railway projects, such as the Rishikesh–Karnaprayag line, are under construction but not yet functional in these areas. Thus, railway connectivity currently covers four districts in Uttarakhand.
