Rockfort Express: திருச்சி அவனது கோட்டை, இரவில் சென்னை வரை வேட்டை, அவன் தான் மலைக்கோட்டை. - Vijay Baradwaj

Its a good concept. But it doesn't mean that all trains must be converted. Overnight long-distance trains are good in with Locos. This concept is good for short time travels maybe till 6 hours and day travel. It has better acceleration and consumes low power and saves time in changing locos or reversing.
