A misspelled name on your Indian Railways ticket is generally not an issue, provided you carry a valid government-issued ID, such as your passport or driver’s license, during your journey.
Additionally, if the last letter or letters of your surname are missing, it is not considered a problem. This is a common occurrence due to the character limit imposed by the Indian Railways ticketing system. Rest assured, your ticket will still be valid as long as the essential details match your ID.
