No experience captures India quite like a long train journey. Indian Railways operates one of the largest networks in the world, with more than a dozen thousand trains running every single day and over 7000 stations connecting megacities, temple towns and remote villages. For travellers, the railway is not just transport: it is a rolling cross-section of the entire country.
Understanding the carriage classes
The class system looks intimidating at first, but it follows a simple logic: the higher the class, the more privacy and cooling you get.
- 1A (First AC) - air-conditioned lockable compartments with two or four berths, bedding included. The most comfortable and most expensive option, often close to airfare prices.
- 2A and 3A (AC 2-tier and 3-tier) - air-conditioned open bays with curtains (2A) or without (3A), berths stacked in two or three levels. The sweet spot for most overnight journeys.
- SL (Sleeper) - the same berth layout as 3A but without air conditioning, windows open to the breeze. Authentic, sociable and very cheap; fine outside the hottest months.
- General (unreserved) - no seat guarantee and serious crowds. Avoid it on long routes; for a 30-minute hop it can be an adventure.
Booking tickets as a foreign traveller
The official portal IRCTC sells tickets online, and registration with a foreign email address is possible, though the verification steps take patience. If you prefer a simpler interface, agencies such as 12Go or Cleartrip resell the same trains for a small fee.
Popular routes fill up weeks ahead, so two mechanisms matter. The Foreign Tourist Quota reserves berths on many busy trains exclusively for foreign passport holders and can be booked online or at dedicated counters in major stations. The tatkal quota opens one day before departure for last-minute travellers - tickets cost a bit more and sell out in minutes, but they rescue many an unplanned trip.
Eating on the rails
Food is half the fun. The chaiwala walking the aisle with his kettle and the cry of chai chai garam is the true soundtrack of Indian railways - a cup of sweet milky tea costs a handful of rupees. Long-distance trains often carry a pantry car serving simple thalis, biryani and snacks directly to your berth. At longer stops, platform vendors sell regional specialities; experienced travellers know which station is famous for which dish.
Routes worth planning a trip around
- Delhi - Agra expresses - the Gatimaan Express reaches 160 km/h and makes the Taj Mahal an easy day trip.
- UNESCO toy trains - the Darjeeling Himalayan Railway, the Kalka - Shimla line and the Nilgiri Mountain Railway climb through tea gardens and forests on narrow-gauge tracks built in the colonial era.
- Konkan Railway - the Mumbai - Goa line hugs the western coast across hundreds of bridges and tunnels; in monsoon season the scenery of waterfalls and green cliffs is spectacular.
- Luxury trains - the Palace on Wheels and the Maharajas Express turn the journey itself into a five-star hotel, with fares starting at several thousand US dollars.
Practical tips for the journey
- Bring a light chain and padlock to secure your bag under the berth at night - every station stall sells them.
- The lower berth doubles as shared daytime seating, so do not plan to sleep there until evening.
- Major stations are enormous; arrive early and check the coach position boards on the platform.
- The app Where Is My Train shows live running status and your coach position better than any timetable.
- Toilets come in two styles, Indian squat and western; carry your own paper and hand sanitiser.
Give the railway at least one overnight journey. Somewhere between the chai rounds, the shared snacks and the sunrise over passing fields, you will understand why the train is called the essence of India.
