This is a very popular train on Konkan Railway and very difficult to get a Sleeper class reservation. I would request the railway authorities to increase the no of sleeper coaches on this train. The Netravati and other Kerala bound trains run with 12 Sleeper coaches. Even the Konkan Kanya Exp should have 12 sleeper coaches. I'm sure the engine will not be affected with the extra load as the WDP-4 is capable of handling such loads.
