Why are train coaches being cut down?

As a regular passenger of the Dhaka-Chittagong route, I am disappointed with the Railways' decision to cut down the number of coaches in Turna and Mohanagar trains. 

It is very difficult to acquire train tickets as it is. I can't remember seeing a single empty seat in coaches in my past few years of travelling by train. Reducing the number of coaches will make it even more difficult for passengers to get tickets. 

As a taxpayer of this country, I have the right to ask whether there is any valid reason behind this decision. Railway is purchasing a number of new coaches, as far as I know. How is it that, instead of increasing the number of trains and coaches as expected, they are now reducing them? 

I request the concerned authorities to reconsider their decision and take the citizens' plights into account.
