Check whether the train and route offer coupe allocation in the class you are booking
Book the ticket through the official railway website, app, or authorized booking counter
Select the required class and enter passenger details
Look for the special request option for coupe or cabin preference during booking
Submit the request if the booking system allows it
If booking at a counter, ask the clerk to note your coupe preference on the reservation
After booking, contact the railway helpline or station reservation office to request a coupe
Make the request well in advance, since coupe allotment is limited
Carry valid ID proof for all passengers during travel
Check the PNR status and reservation chart before departure
If allotted, confirm the coupe details from the coach attendant or chart
Be prepared that coupe allotment is not guaranteed and depends on availability and railway rules
