Both Tilak Nagar and Delhi Cantt Metro Station are 4-5 Kilometres away from Delhi Cantt Railway Station.
Interchange at Rajiv Gandhi Metro Station for Blue Line is much more convenient than the long walk at interchange at Delhi Haat INA Metro for Pink Line. He's coming from New Delhi Railway Station NOT Hazrat Nizamuddin Railway Station.
Even People from Delhi Cantt themselves don't find Delhi Cantt Metro Station convenient when coming from Yellow Line. ЁЯШВ
