There seem to be some glitches. When i click on "Get Return Journey", for some trains it shows an entirely different train. I have been noticing this for quite sometime now but unfortunately havent been careful enough to note the train numbers. the two instances that i remember are
1. 2840 chennai howrah mail shows its return journey as 2841 coromandal express.
2. 2305 howrah rajdhani shows its return journey as 2304 poorva exp.
There...
more... are other trains as well but as i said i cant recall them now. sorry. is it that the string that you have used takes the next or the previous train number and doesnt match the train name. i guess matching the train name as well shud solve this glitch
