If the number of trains cannot be increased due to existence of single line in many patches of the route, then at least the existing trains should be operated with 24 coaches.
Surprisingly most of the 23/24 coach trains from CSTM are bound towards IGP/North/ East and those going towards Pune/South have shorter rakes. Ror example rake lengths of the following important trains are too short-

11027-CSTM-MAS-19 coaches-Daily

Above trains should be augmented with 23/24 coaches on priority to serve more paxs before the doubling is completed & more trains can be introduced on the route.
