Reading the news I see that so many innocent lives and then after that loss of 90crores to railways, moreover trouble faced by countless travelers. Why this all happened at first place ?

As per newspaper:

Railways suffered an estimated loss of over Rs 90 crore as a furious mob set ablaze 15 coaches, including an AC coach and locomotive of the Saharsa-Patna Rajyarani Express (12567) and five coaches and the locomotive of Samastipur-Saharsa passenger train at Dhamara Ghat on Saharsa-Mansi section under Samastipur division of East Central Railway (ECR) after 37 passengers were killed by the running train around 9am on Monday morning. Railways, however, put the death toll at 28.


Cause behind the incident, prima facie it appeared that the mishap took place while the victims were crossing the tracks when Rajyarani Express was coming from Saharsa end.

Now it is not clear how come so many people not noticing a train at once ? We see people crossing tracks lots of time , sometimes tragic incident happens but mostly due to negligence of people but its not clear how come so many people are making mistake at once ?

Definitely one should not cross railway tracks or if crossing then should take utmost care for upcoming trains ? Certainly a bad incident. RIP all those died in this tragic accident.
