Two times in every year I travell by this route from Mumbai to kanpur via jhansi ,I hv experience the track between jhansi and kanpur are good ,only 20 to 30 train passes daily by this route hence it is maintained very well.the cause of accident I believe is 2 reason
1. improper maintenance and ignorance of coach by rail authority .every time the wheel should b checked while resting
2. Overcrowding of passengers especially in general coach which gives lot jerk on the the track
...
more... In the past there has been no accident in this route .
Capacity of general biggie is 90 to 100 but generally there 150 to 180 ppl .on an average almost 4500kg weight is extra.
The only way to curb such situation is railway shd start more jansadharan train on busy route and it Shud b at least tri-weekly.
