रेलवे स्टेशन कोड क्या होते हैं? कैसे दिए जाते हैं?

Station codes = unique alpha identifiers for railway stations.

Examples:

• NDLS — New Delhi
• BCT — Mumbai Central (Bombay Central historic)
• HWH — Howrah
• MAS — Madras (now Chennai Central)
• SBC — KSR Bengaluru City
• JP — Jaipur

Code structure:

• 2-5 letters
• Usually derived from station name (sometimes anglicized historic name)
• Major junctions get shorter codes
• Suburban stations get longer / suffixed codes

Usage:

• Printed on tickets
• Used in PNR system
• Timetables & enquiries
• Used for booking by code (faster than typing full name)

A full code-to-name list is available on Indian Railways' website. Major code changes (like MAS → MAS, but station name changing from Madras to Chennai) keep the historic code for system compatibility.
