Train 18 - तेरी प्यारी प्यारी Livery को किसी की नज़र न लगे

To be frank, almost all non-AC LHB with 130 run on the grand chord route. And it is not the inefficiency of speed but high congestion that holds back the performance of those trains. This is coupled with the fact that most of the other trains still run at 110 MPS. Once all are upgraded to LHBs and cleared for 130, average speeds will go up. And trains trains along Delhi-Kanpur are getting LHB one by one (which is more than other routes) which will make this thing real, in future.
