If you are planning to book an entire train of 18 coaches for 7 days then the registration fee will be Rs. 9,00,000/- (Nine Lakh)
If you need more than 18 coaches in a train then extra coaches can be added but extra Rs. 50,000/- will add the registration fee. For example, if you need 19 coaches on a train then you will have to pay 9,00,000+50,000= 9,50,000 (Nine Lakh Fifty Thousand)
If your journey is of more than 7 days then an additional Rs. 10,000/- per day/per coach will add to the registration amount. For example, if you need 18 coaches to train for 10 days then the amount will be 9,00,000+30,000= 9,30,000/-
