That's OK but new trains of other zones are waiting to GOA destination through this route instead of KR.. so As they going to depart from long distances so proper timings and slots are not getting to run them so a double line is very much needed one and also bottleneck braganza ghats gradients need bankers and takes 1.2 hours just between castle rock to Kulem which makes difficult to run and make crossings also in this stretch if Doubled and Electrified and can be good for some instance to run some more trains easily
