Commercial and Social Activities are totally different @Mridul. Mixing such things are not possible. Simply IR Management is responsible. There can be many reasons for such thing.
Signal didn't worked properly, LPs are overburdened in their work. Equipment fault, anything is possible. I am absolutely not in favour of the current BJP Cabinet. Rail Ministry should open more vacancies to balance the burden. And proper checks to be done of Equipments. (But this a true fact that LPs are overburdened and have to work overtime).
