One of the best places for railway reservation in India is irctc cleartrip website. The IRCTC Clear Trip allows all customers to book train tickets and makes search trains easy task. It also offers cheap air tickets, flight tickets, International Air tickets, domestic airline tickets in India, apart from railway tickets. It works in association with Indian Railway Catering and Tourism Corporation Ltd.
What I find of real interest is train calendar and hotel packages for hotels in India. Some very good deals are available. It is very much clear that it is one of the best travel website that is going around for frequent travelers in India.
To make website worthwhile Cleartrip is extending its business by making its presence on mobile phones as well. For this purpose they have developed a special API.
Other issue when it comes to dealing with large business like railway is to handle the complaints and to answer the user queries. For this purpose I would recommend people to follow the official irctc enquiry numbers. If you have any problems you can ask and clear your doubts so that you can proceed to login at irctc.co.in for reservation.
