When purchasing a reserved ticket on any train operated by Indian Railways, one's required to enter the age and gender (male or female) of all passengers. However, for various reasons, I don't wish to disclose my* gender. For instance, my expressed gender may be different from the one in my identity document (explicitly written or implicitly pictured), or I may not identify with a particular gender.
The standard IRCTC website for purchasing tickets on Indian Railways won't let you through if you don't select a gender.
Is there a way to purchase a train ticket without disclosing your gender? Why does Indian Railways require passengers to disclose their gender at the time of booking?
* Question doesn't necessarily relate to me
