What is “CC” in train?

In the context of Indian Railways, the code “CC” stands for AC Chair Car class of accommodation.

Key features:

• Seating (not sleeping berths) in an air-conditioned carriage.
• Layout typically 3×2 seats across the width per row.
• Typically used on short to medium-duration trains (day travel) rather than overnight journeys. So when you book a “CC” ticket you’re getting a comfy AC chair, not a sleeper berth.
