The problem is that here you will find metro network because here so many lines and almost all of them are interconnected. To understand metro route you can do one one thing where ever you want to go search the route on Google I mean search location from staring point to end destination there you will get clear route and line understanding. In Delhi there are many destinations which you can cover. Akshar dham mandir, Lotus temple, Bangla saahib Gurudwara, Prachin Hanuman mandir, Sheeshganj gurudwara, Red fort, Chandni chowk market, Chhatarpur mandir, purana Qila, Vishnu stambh, India gate, war memorial, Iscon temple, Agrasen ki Bowling etc.
