Kolkata - Navadvipa Trains Details Saturday, 16 February 2008 There are two classes of trains available. One is an express train, and the other is a local train. The express train, besides being faster, is more comfortable and better if you are carrying luggage. There is also a lower chance of theft on these trains. Howrah station and the local trains are quite notorious for pickpockets and luggage theft, so be very careful with your valuables!
