I am placing my views here from what I have observed... I may be corrected if required :
There are already lots of traffic to be manageable on a single track... If SWR is complaining for just one service that KRCL blocked owing to lack of running path then question surely needs to be raised on SWR politics.
Vasco Da Gama...
more... is with SWR and How many outstation trains actually connect Vasco Da Gama, other than a few weeklies belonging and travelling to KA, in SWR, it just has a daily train to Delhi, one weekly to Patna that's it. Goans have long since been demanding many trains especially restoring those trains running in MG era, a daily intercity to Belgavi, Hubbali, a couple more passenger/DEMU services between Vasco and Kulem but each and every demand of Vascoites are being shot down by SWR citing operational constraints and guess what do they do with slots... Run more and more freights, use revenue from Mormugao Port in Goa and use these in Karnataka.
Why they have even declined offer to start Madgaon terminating running trains till Vasco Da Gama. For eg Extension of Mangaluru Madgaon Intercity till Vasco was declined by SWR. Just ask native Goans esp those who unfortunately fall in SWR stretch between Vasco and Kulem how desperately they need more services and how their demands are left unfulfilled and you will certainly feel that what KRCL has done is correct. Even with whole load of traffic in single line it's difficult to manage a new train add to it numerous festive specials.
Further we can also discuss how bus lobby rules SWR and how they do not permit running a daily Superfast over night train from Bangalore to Pune and Mumbai and that Over night slot is used by Bus lobbies. SWR is pro bus lobby and it's bus arm KSRTC has vested interest and that is reason you do not seen Superfast high speed trains between Mumbai Bengaluru.
To sum up: The same day this news came which proved SWR just wants to run freights :
"Due to increase in freight movement which causing congestion in Belagavi – Miraj Section and passengers trains are running late. To ease the movement and ensure punctual running of Mail/Express trains the following passenger trains will be cancelled as detailed below: -
1. Train No. 51405 Miraj - Castle Rock Passenger commencing journey from Miraj on 28.02.2020 & 29.02.2020 will be cancelled.
2. Train No. 51406 Castle Rock - Miraj Passenger commencing journey from Castle Rock on 29.02.2020 & 01.03.2020 will be cancelled.
3. Train No. 51431/ 51432 Miraj – Londa – Miraj Passenger commencing journey from both sides on 28.02.2020, 29.02.2020 & 01.03.2020 will be cancelled."
So unless one cannot change their own ways, one cannot point others...
