Not to discourage you, but most likely, you'll get the stock answer, 'Ghat restrictions'. People have been complaining high and low about running new trains on Shiradi and Braganza ghats. Even after getting a legal notice from KA high court, SWR has not made any progress in running new trains on these routes. Makes one wonder, whats the point of doing a gauge conversion if they knew that they can't run as many passenger trains on these routes again.
