Train ticket reservation on Internet

I guess Indian Railways is the biggest transport medium present in India. In last few years, Air travel and Road travel are also picking up but still railways is still on top. We also saw some modernization steps taken by Indian railways.
1. Train ticket reservation on Internet and getting ticket through courier(i-Ticket)2. Train ticket reservation on Internet and printout & Identity proof as Ticket(e-Ticket)3. Upgrade of Tickets from Lower classes to upper classes.4. Help lines with Voice recognition - you speak name of train or station and get details by machine 5. Many more ....
Other than the main ticket reservation website i.e. www.irctc.co.in, there are few more websites related to Indian railways.
1. http://www.indianrail.gov.in/ - Main website which was launched few years back. Almost every static (non-frequently changed) information can be found here like. train between stations, train schedules and also PNR status.
2. http://www.irctc.co.in - Website for railways ticket reservation.
3. http://www.indianrailways.gov.in/ - Official website of railways ministry. Most of the historical information can be found here. You can also go through the rail budget on this site.
4. http://www.erail.in/ - Another inquiry website which runs on Ajax technologies.
5. http://www.trainenquiry.com- This one is quite useful because it shows current running status of trains on internet.

You can provide train number and running information can be retrieved for train running for today,tomorrow and day-after-tomorrow.
I find it very useful because it really helps the passenger to plan according to latest running information. Earlier we used to use one inquiry phone number, generally 1330 or 1335, which announces all the trains status. Generally voice quality is not good on these help lines and if you are traveling in less popular train, this number may not be useful for you.

Other than this, Train arrivals, Train departures and Train time tables are also part of this website.
I find this useful because India qualify for the perfect use-case where trains generally get delayed and people waste their time waiting on station's platform.
Use internet and avoid waste of time and energy!
