Book your own coach in Delhi Metro

Tourists, foreign travellers and government or private school children, NGOs running schools for differently able children can book coaches for metro tours for anything between Rs 30,000 and Rs 50,000.
Delhi Metro Rail Corporation, under its Policy on Reservation of Car(s)/Train, allows tour operators, any government or private agency, or an individual on behalf of a group or school to book cars or trains from any station of the metro network including the Airport Express line.
The booking tariff consists of fares for the number of passengers and facilitation charges toward offering special facilities to the group, consisting of not less than 45 passengers up to 150 passengers.

Only the coach of the longest train consisting of 8 coaches can be booked for a group.
DMRC does not charge facilitation charges from government schools and NGOs running special schools.
These facilitation charges, in addition to the applicable fares, consist of Rs 50,000 for one coach on Line 1, 2, 3/4, Rs 30,000 for Line 5 and Rs 40,000 for the Airport Express line.

These fares also get escalated at the rate of 10 per cent from April 1 of each financial year.
However, if the originating and terminating stations are on different lines the booking on multiple lines will be treated as multiple car booking.

Some special facilities offered by DMRC are viewing the Metro Museum, textiles, handicraft exhibition at nominal charges, free parking facilities at the station for the group, welcome message or special announcement for the group besides presenting mementos to travellers. One member of the DMRC will also be present with them to guide them through the journey.
