One of the best advantages of north campus- You can book your railway tickets here. There isn't any rush here most of the times and the people are polite and good.
There happens to be two counter but now only one is available and others are closed, if you went there early in the morning chances are high for your confirmation of tatkal tickets otherwise for general reservation ticket it's good choice because few people are there. It's in the Delhi University campus but haven't seen they are checking identify card of person so I assume its open to everyone.it's on the first floor of University campus with other useful office for University students like Post office, SBI bank, ICICI bank, DTC counter for bus pass. It is based on North campus. I assume it may help you. Thanks for reading.
