Single walo yesa kya problem hai ki Jo wo CR Rajdhani ki PushPull me Nahi Dekh PA rahe he
Didn't get your point... Need some elaboration.
If you mean to ask why some people are voting for single loco even though there is a latest technology like Push-Pull is available, then let me tell you that this poll is actually a battle in between Orthodox and Un-orthodox. That said, let's say you have grown up mostly seeing a train being hauled by a single loco at front. So single loco is the Orthodox method (Even used today for nearly 99% passenger trains). Now this poll aims to find out how people react to a change.
