Can anyone tell why Krishna Express is getting delayed last two days. Starting from Tirupati, by the time it is reaching BZA, it is about 4 hours late. I am travelling from TPTY to VSKP, with TPTY to BZA by Krishna express and BZA to VSKP by Janmabhoomi on 1/5/2013. What do you think, will Krishna express reach BZA on time on May 1st?
