I mean both have an impact and are inter-related. There is considerable political influence at play and the zone is also reluctant to expand operations. I am just saying that the zone is not completely blameless and there has been a serious lack of efforts from the zone regarding this section.
Infrastructure usage is not at a peak. It is far from optimal. No one is asking for round the clock services. The section currently sees a maximum of 6 trains per day on Mondays, to a minimum of 3 trains on Fridays. All that is to be done is to at least make sure that the empty slots are utilized so that...
more... the maximum train (apparently 6) count is met on all the days. For trains from HWH/HYB/MAS the respective zones had agreed to provide the rakes and the loco links for the GTL-VSG stretch will be mostly provided by SCR, removing a burden from the zone in providing rakes and loco links.
While it is a very challenging ghat section ( the ruling gradient is the same as the Kasara ghats!), routine maintenance is never done by blocking the line. The capacity of the line is only determined by the slowest section, in this case the CLR-QLM section ( which again has 3 spots with sidings for enabling cross-overs). The same point (regarding the maximum capacity) has been mentioned by the zone in the HMRDA agreement on the Shiradi ghats also.
There are some infrastructural constraints and political limitations, but the zone is not entirely blameless in it's method of handling this section. Even with existing limitations, there is still quite some good services that can be provided to people.
