Agree on your point. Instead of just rake utilization, swr should think other way. That is why also suggested in another blog to utilize cancelled rakes of 56921/2 on the same timings morning 7 am departure from Dandeli and evening 6 pm departure from Ubl, this way it will be more useful. This particular train can run entirely like Sur-Ambevadi-Sur passenger. In this way two trains will be ensured.
