Transport catering: railways, airlines, ships and space

Transport catering feeds people on the move in trains, aircraft, ships and spacecraft, where space, weight, time and food safety over long holding are the big challenges.

Railway catering

IRCTC (Indian Railway Catering and Tourism Corporation) manages catering on trains and at stations, mostly through licensed caterers.
Base kitchens near big stations cook and pack meals in bulk for trains.
Pantry cars on long-distance trains heat, store and serve meals on board.
Static units at stations: food plazas, refreshment rooms, food stalls and low-cost Jan Ahaar outlets.
E-catering lets passengers order on an app from listed restaurants and get food at their seat at a chosen station.
In premium trains such as Rajdhani, Shatabdi and Vande Bharat, meals are usually booked with the ticket.
Challenges: huge numbers, tight halts, hygiene in a moving coach, fair pricing and waste.

How an airline meal reaches the passenger

This is a commissary system with cook-chill. Special meals (vegetarian, Jain, diabetic, child, low-salt) are ordered at booking. Low-cost airlines often sell snacks on board instead.

Problems special to airline catering

Weight and space: every kilogram costs fuel; galleys are tiny.
Time: meals must be loaded before departure and served within a short flight.
Food safety: food is held for hours, so chilling and reheating must be strict.
Taste: dry, low-pressure cabin air dulls the sense of taste, so food is seasoned more.
No open flame on board: only electric ovens and boilers.

Ship catering and space catering

Ship cateringFood is cooked in the ship's galley. Cruise liners run many restaurants, buffets and room service; cargo and naval ships have a crew mess. Stores for the whole voyage are planned in advance, with large cold rooms and dry stores. Ranges have rails (fiddles) so pans do not slide when the ship rolls. Fresh water, fresh produce and waste disposal at sea are limited.

Space cateringFoods are prepared on Earth in single-serve packs. Main types: thermostabilised (heat-processed in pouches), rehydratable (dried; water added), intermediate-moisture (dried fruit), natural form (nuts, biscuits) and powdered beverages. In microgravity crumbs and drops float, so tortillas replace bread and salt and pepper are given as liquids. Food must be light, keep for months without a refrigerator and stay tasty. In India, DFRL, Mysuru develops ready-to-eat foods for the Gaganyaan human spaceflight programme.

All four are a restricted market: only passengers or crew can buy the food.

In a real kitchen

Every transport kitchen is really a cook-chill or commissary kitchen: food is made far from where it is eaten. So the manager's first job is temperature control from cooking to serving, plus special meals for diabetic, Jain or vegetarian travellers.

Exam angle

2 marks: “Name four types of space food.” Thermostabilised, rehydratable, intermediate-moisture and natural-form foods (plus powdered beverages).

5 marks: “Write a short note on airline catering.” Flight kitchens near airports cook, blast chill, tray and load meals; galleys reheat; special meals ordered at booking; problems of weight, space, time, food safety, taste.

10 marks: “What is transport catering? Explain railway, airline, ship and space catering.” Define; for each mode give how food is produced, how it is served and its special problems; draw the airline meal flow; end with the common need for temperature control.
