Fire accidents in indian trains

For last few month there is a high rise in no of accidents caused by fire in train compartments.  Why sudden rise in such accident ?. Are our reservation coaches safe ? . Is it due to design problem or is it due to overloaded usage of compartments without proper maintenance.  Why railway not coming up with solutions.  R we risking ourselves when we are booking a reservation ticket.

Main reason for the fire accident is lack of maintenance , over usage of the compartments . there is no sufficient time for the heat generated to cool off before next trip in most of the ac coaches . More over some of the new coaches are having highly combustible materials.  Railway should come up with fire retardant material compartments for a/c coaches . It is also time to shift from old school of design to modern school of design . Start designing coaches in line with  European style of coaches atleast for first, second a/c class .
