Shifting the blame onto others is one of the oldest and widely used methods of concealing one's own share of a fault or failure. Of late, Bangladesh Railway has hit the headlines by resorting to this outlandish subterfuge with the obvious objective of shirking its responsibilities towards maintaining the shabby railway track, the lifespan of most part of which has expired much earlier. While BR has high records of derailment of locomotives and rolling stocks and other accidents, bending of rails seems to be becoming more frequent recently.
Experts say there are several reasons behind buckling of railway tracks. One having preliminary knowledge of science knows very well that steel or iron bars expand whenever heated. It is for this simple reason that a minimum space is left between two consecutive rails to accommodate linear expansion of the tracks under excessive heat. But BR comes forward with a simple equation, one of blaming only heat without reference to other factors. Railway tracks' accumulation of heat under the sun and expansion is a natural phenomenon, the impact of which can be avoided with human intellect - by ensuring measured space between rails. Only heat cannot make tracks buckle whenever there is enough space. The responsibility of ensuring sufficient space rests directly upon the railway authorities.
Quality of the rails like compactness has also a lot to do with preventing risky bending of tracks. According to global standard, the weight of rail per meter should ideally be 60 kilograms, and in that case it is not supposed to be a problem if temperature rises even to 50 degrees Celsius. But Bangladesh has the record of track-bending when the temperature is much less than that, and even in winter. Use of low quality tracks can explain such a queer phenomenon.  
Rising temperature is not the only culprit for the buckling of tracks. According to experts, more than 70% of the century-old railway tracks have reached the end of their lifespan. However, Bangladesh Railway finishes its job simply by placing the blame squarely on temperature level. It is nothing but an attempt to hide their failure in properly monitoring and maintaining the tracks.
