.
1) Auto: Legal fare: ~Rs 120 (Night Rs. 150). 12kms. 25-30-45 mins depending on traffic. Exit through PF#01 side of NZM.
2) DTC Buses: Exit from Pf#01 side of NZM. Walk to the main road (It’s a bit long so those having heavy luggage are recommended to take a cycle rickshaw). Bus#403,405 is frequently available from Bhogal Bus...

Similarly when starting from DLI, walk to the bus stop and hop over a 403 or 405 which'll drop you at Bhogal.
3) EMU: Priority 3 goes to the EMUs. Cheapest and fastest. Just a bit less frequent, if you can match the timings of one that goes to DLI, take it! Takes 25-35 mins.
4) Delhi Metro: Poorly connected points through DMRC. Take an auto till Jangpura Metro station, then Violet line till Central Secretariat then Yellow line to Chandni Chawk. Not recommended.
