Bhai, commute karne se matlab hai, ab wo chahe EMU mei karo ya DEMU mei ya DMU mei ya MEMU mei.
Jaake kisi bhi daily commuter se pucho ki do they know the meaning of HPDMU, DEMU, DHMU , MEMU , EMU ? No common people don't know anything about all this "hickory-dickory". They just want to travel daily or say commute properly to their working area with cheapest fare as compare to Buses.
Electrification jaruri nahi hai har chiz ke liye. Biggest problem for running a EMu train is minimal...
more... Platform hieght requirement. So instead of wasting money on raising platform height of ALL intermediate stations and electrifying the whole section, why don't railway provide DEMU and regular DMU for this section which is more accessible and people friendly.
