Ideally, you should not travel in train on waiting list tickets. In premium trains such as rajdhani, shatabdi, and duronto,
passengers with PRS waiting list tickets, if found, are fined and asked to deboard at the next halt.
In other trains, the TTE does not interfere but traveling with a waiting list e-ticket is not advisable
as it causes inconvenience to other passengers. Fully waitlisted e-tickets are automatically canceled on chart preparation.
