Dear friend a very unusual route has been chosen for the Mum-UBL train. The unfortunate part is that this train need a timeslot in the Londa-MAO section which is extremely difficult, as new trains had been denied on the section since several years due to non availability of path.
Even if we assume that the path has been created by suitable capacity augmentation measures, or the planned doubling project is completed, why not to extend the train to Bengaluru and ensure a good patronage to the proposed 24 coach daily train?
