** Since the construction cost of a suburban railways is very less as compared to an underground/ elevated Metro, IR keeping fares of AC suburban trains higher than the metro fare is totally unjustified.
** Suburban AC fare should actually be lesser than the metro fare
** IR always have a very strong tendency to recover the losses incurred in non ac class through the AC class, and in process make it very costly and lose its profitable traffic & market share to other modes of transport.
