What types of trains operate between major stations?

Major stations in India are served by several types of trains including Rajdhani Express, Shatabdi Express, Duronto Express, Garib Rath, Superfast Express, Mail Express, and Vande Bharat trains. Rajdhani trains are fully air-conditioned long-distance trains with limited stops and meal service included in the fare. Shatabdi trains are day-travel trains connecting cities within a few hours. Duronto trains are non-stop trains that run without any commercial halts between origin and destination. Vande Bharat trains are modern semi-high-speed trains with reclining seats and faster travel times. Each category serves a different travel need and budget.
