I'm travelling India for a few weeks. We plan on doing a few overnight trips from New Delhi and do not want to carry all our luggage with us. We don't have anything really valuable but it would be very inconvenient if all our clothes went missing.
If you'll be traveling on train from New Delhi, then you can use the cloak rooms and safety lockers available at New Delhi railway station.
Most major stations have cloak rooms and lockers where you can leave your luggage, on payment of prescribed charges. This passenger amenity ensures safe custody of your luggage, giving you the freedom to spend a day or two as you desire. The process of depositing your luggage in the cloak room has been simplified for your convenience. All you have to do is to deposit the luggage duly locked, where upon a receipt will be given to you. This receipt, duly signed as an acknowledgement of having received your luggage, should be surrendered along with the prescribed charges at the time of delivery. Delivery of luggage will not be done without the surrender of your receipt. Pleaese ensure that all baggage/hold-alls/travel bags are locked securely. Otherwise, these may not be accepted by the railway personnel.
You will have to produce your train ticket, and Identity card (this is needed at many stations). There is a nominal hourly rate charge, which is calculated per piece of luggage. Your luggage must be locked.
The current rates for using Cloak rooms and Storage lockers:
Duration Cloak Room Storage Locker For first 24 hours or part thereof Rs 15 per package Rs 20 For each subsequent 24 hours or part thereof Rs 20 per package Rs 30
If you are using the Delhi Airport Metro Express (at the New Delhi station), there is a cloakroom just outside the barriers. To get here, you cross the from the mezzanine level (between the bottom arrivals and upper departures levels), across the catwalk towards the metro, and walk past the stairs/entrance to the station.
Bag does not need to be locked. I believe it's cash only. The photos show the hourly and flat-rate prices to store luggage (visited February 2019).
There is a service called bagdolo which offers cloakrooms all around Delhi, you can find the nearest one and drop your luggage there. They charge around Rs 80 ($1.2) per bag. They also provide safety seal to secure your luggage.
They also have service in several other major cities of India. It can be booked online through their website/app.
