Assuming it runs at 130 kmph; then also RNC Raj left New Delhi first and both trains are non-stop upto CNB. In that case, why would the train backwards in the sequence(12560) OT the one in the front(RNC Raj); especially when the train in front is a Rajdhani class train. Also, would the controllers also have taken the same action had it been HWH Raj in place of the RNC one?
